Anyone have the Canon SD300 camera? - 02/03/2005 19:04

I can't afford it yet, but this is the camera i want to buy when i can....i was mostly wondering how fast it was compared to other cameras....Especially how fast it is in low light situations since most other cameras take forever to focus....

I was going to get one this week, but noticed that Canon just announced the SD400, due out March 25th. Same camera, but 5 megapixels. I'm gonna wait a couple weeks and get that one. You can preorder them at Amazon and view the specs on DPReview.com.

The SD300 is VERY fast. Both in startup time and in focusing time, etc. the review on dpreview.com will give all those specs.

I HAD an SD300 until I read about the SD400 and SD500 which are coming out this month. I returned it to Dell within the 21 day return policy...

To me, the new features that is present in these 2 cameras are worth the wait. USB 2.0, better LCD screen, ability to zoom (digitally) when in movie mode, 5 megapixels in the SD400, some enhanced coloration toys, customized settings for remote picture mode, and a few others. Oh yeah, for the same retail price - although I doubt the street price for the SD400 will be as low as the SD300...

I loved the pictures that the SD300 took, although it is generally thought to have "soft edges"...

It's a great point and click kinda camera, and the form factor is amazing.

The SD500 is bigger, but I gotta see by how much before I decide between the SD400 and SD500...

I'm extremely interested in how well these cameras do in low light situations.

It looks like the form factor is the same as the other models in the ixus line, but if these new ones do better in low light, I might just have to get one. That's been the bane of my current ixus-line camera.

Not as good as a larger camera. It has a tiny lens (it's a tiny camera)... The indoor shots I took were pretty grainy. The more light, the better. The SD500 would be much improved, but is larger than the SD300/SD400...

Here are some samples of shots I took with it: http://www.flickr.com/photos/jonbauer/

I don't care much about grain, what I want is a camera that can take an indoor shot (standard indoor lighting, incandescent or fluorescent) without a flash... and not need a hold-your-breath-and-don't-move-the-camera exposure to do it.

I don't need to take pictures in candle light. I just want to be able to take indoor shots at office-lighting levels and not have them come out blurry because my heart was beating during the exposure.

My current camera (ixus 300) can't do that.

The camera takes pretty impressive pictures, but because it's so small, it IS subject to blur as holding it perfectly still in your hand is difficult. I've read that a lot of people use the multi shot mode to alleviate this issue as the 3rd of 4th shot is usually a lot less blurry than the first one...

I recommend that you go get a demo of the camera somewhere. The pictures it takes are pretty impressive, in my opinion.

I'm in the EXACT same situation. I was going to order one the DAY they announced the new ones. Now I'm holding off. I just have to decide it I want to wait so the SD300 comes down in price due to the new ones or if I want to go with the SD400. =]

Oh, and Tony, I'm not sure if you've seen one in person, but the form factor is actually smaller. The SD line is ridiculously small, even compared with the S series.

Can't get one in that form factor.

For me, the form factor is very important.

And Loren: Yeah, I noticed that as I was reading the review on DPReview. Pretty damn sweet. 3x zoom in something that small is amazing. Definitely drooling for one now.

Re: Anyone have the Canon SD300 camera? - 02/03/2005 22:35

You should run by a Best Buy or something and "fondle" one. I kept going back and forth between a Sony T1 and an SD300 for literally half an hour, just getting the feel of each one. The T1's speed is just phenomenal and it feels amazing, but the SD300 won me over. The SD20 is also pretty damn amazing... it's smaller than the SD300! It's getting to be the size that makes you scared you'll loose it it's so small. I just sold my S200 and am chomping at the bit for a new camera. It sucks that the SD400 isn't out until the end of the month... on the DAY i'll be headed to the desert for the annual kite event I attend. Argh. I guess I'll have to get an SD300 to hold me over... but I bet the prices won't drop until after then.

Don't be snowed by the zoom factor. I always look first at the widest wide-angle the lens can do. This is one of the places that the Canon S60/S70 line has traditionally beaten its rivals, although the brand-new Ricoh Caplio R2 looks nice as well. You can always get closer to your subject. You can't always get further away.

True. But in practice, in the situations I'm using my current camera, I've found that I lament the lack of a good zoom more than I lament the lack of a wider angle.

I'm on the waiting list for a new SD500 as soon as they are available. I currently have an S330 thanks to the recommendations I have gotten here. I was in the market for a bigger camera such as the Digital Rebel or the PowerShot Pro1 but the form factor is what got me sold on the smaller camera.

I had 10,000 pictures/videos taken with my S330 in the first year of ownership because it was always in my pocket. It's been dropped on rocks, cement, and asphalt. Landed in the mud. Lost in the snow during a snowmobile ride (a kind soul found it, turned it on and saw a picture of my CR-V and returned it to me (small town bonus!)) I had it in my pocket during another snowmobile ride that had a snow fall that turned into a rainstorm and the camera would only work in one mode until I took her apart and let her dry out for a couple days by the oil stove. I even have the waterproof case and I have taken it out on my WaveRunner and with me being towed on a tube behind the WaveRunner and behind a friends boat. I have also taken it with me during the birthday parties of my nephews and neices when they are at the pool. Nobody else has a camera so it really lights up the kids eyes to see the pictures and videos of them diving for the first time or finally swimming without anyone holding onto them.

My S330 has really proven to me the sturdiness of the Canon cameras. I only hope I have the same joy with the SD500. 7 megapixels, zoom in video mode, unlimited length (up to 1 gigabyte) of video clips. It was pretty much a nobrainer once I started reading about this camera. The price I have been given on it as of now is $629 Canadian. I hope to do a little better then that once it is released but I know the accessories are gonna bring my cost up a bit.

Re: Anyone have the Canon SD300 camera? - 06/03/2005 18:37

I was taking a bunch of pictures today around sunset (mmm... long shadows), which meant I didn't have full daylight to illuminate things. However, I foolishly insisted on using my long zoom lens (300mm on my camera == 450mm on a full-frame camera). In practice, I only got really sharp photos if I braced the camera against something (e.g., a light pole) or cranked up the sensor speed such that I could do a 1/1000 sec exposure. This is with my six megapixel Nikon D70.

Pseudo-moral of the story: unless (or perhaps, even if) you've got some kind of optical image stabilization, once you get to six megapixels or up, you're in a world where even minute jitters of your hands directly translate into not-quite-sharp photos. Left unchecked, this may create tendencies to blow money on over-built tripods or a wide variety of other senseless camera accessories.

Buyer beware.

Re: Anyone have the Canon SD300 camera? - 06/03/2005 20:51

Should have bought a Canon

Then you could have had an affordable 70-300mm image stabilised lens...

I'm surprised you had to go to 1/1000 to get sharp shots, I would have thought you would have got some at least at 1/500 or 1/750.
Posted by: DWallach

Re: Anyone have the Canon SD300 camera? - 07/03/2005 10:34

1/1000 seemed to do the job, regardless of my jittery hands. Below that, it seems like I needed to brace the camera against something like a light pole. Otherwise, I was nailing some and blurring other shots, even at 1/500.

In terms of "affordable" image stabilization, B&H wants $1150 for the Canon EF 70-300mm f/4.5-5.6 DO IS USM lens. That's pretty painful, compared to my $250 Nikon AF 70-300 f/4.0-5.6 ED lens. Of course, it doesn't have any of the whizzy features of the Canon lens, but that's reflected in the price. (The Tamron lens with the same specs costs $150, apparently rolls off the same assembly line as the Nikon lens, and is effectively identical, modulo cosmetic differences.)

Somebody needs to built a lens with specs comparable to Canon's IS lens for under $500. That will be a best seller!

Ah, that wasn't the affordable 300mm IS Canon lens I was referring to. I was talking about the Canon EF 75-300mm f/4.0-5.6 IS USM, which B&H have for only $390...

Canon do, it just doesn't match all the specs of the Canon IS lens you were talking about (optical quality, focusing speed and size are the big differences).

For the record, I have the EF 75-300mm f/4.0-5.6 IS and want the EF 70-300mm f/4.5-5.6 DO IS USM

With the IS I manage to get fairly reliable sharp shoots with 1/350 at 300mm, with some shots at 1/250 and below being sharp as well. I've just noticed that one of my favourite shots of Eryl my wife was 1/180 at 300mm and is sharp (for the bit of the shot that is in focus):

For the cost of the latter lens, I'd imagine you'd just want to go it a step further and get the 70-200mm f/2.8 ($1500, more or less, from both Canon and Nikon, with a similar feature set of bells and whistles) plus maybe a 1.4x teleconverter. Either lens would look quite pretty on your shelf when you leave it behind because it's too heavy to lug around.

In the UK the EF 70-300mm f/4.5-5.6 DO IS USM cost £849 and it weighs 720g.

The EF 70-200mm f2.8 L IS USM and EF 1.4x II Converter combined cost £1,608 and weigh 1790g.

So the combination weighs 2.5 times the weight of the single lens and costs twice the price.

The 1.4x converter loses you one stop, which turns it into and f/4.0 lens. That would make it the same at the short end as the single lens and only one stop faster at the long end.

The deal breaker of course though is that the lens and converter are white

No doubt the 70-200 has measurably better optical quality, but I'm never likely to own one because of the size, weight, price and whiteness.

Re: Anyone have the Canon SD300 camera? - 07/03/2005 19:51

I'm with you on the L-Series vs. DO. The lens length, color and extra 100mm are what put me into the 70-300 DO IS instead of the L series. The 70-300 DO is much less conspicuous when shooting city candids or local sports events than the L-series.

My other lenses are the 24-70 f2.8 L and the 16-37 f2.8 L. I don't feel the need to get anything else (except maybe a fisheye) for some time.

Wow, that's a good deal more money than we pay in the U.S. At that point, it's cheaper for you to book a flight to New York, buy your gear (even paying sales tax), and fly back home again.

In terms of mass, there's definitely a big difference between 720g and 1790g. Interestingly, your Canon 75-300 (with IS and USM, but without the fancy DO optics), weighs only 666g. The Nikon lens (similar optics, but no IS or USM) is 517g. I suppose it makes sense that adding the ultrasonic motors and image stability systems could cost 140g. I'm actually somewhat surprised that the DO version is heavier. I would have thought that with more expensive optics, they could get that weight down. Maybe they're putting in heavier AF motors or a more robust outer shell.

Indeed and those aren't list prices they are street prices. The list price for the DO is £1049.99

I bought both my 75-300 and 17-40 f/4.0 L in the States when on holiday. Thankfully Canon do an international waranty on the lenses, something that is sadly lacking on the bodies.

Mind you, you can only really save decent money if you "forget" to declare them coming through customs, otherwise you would get hit for at least 10% duty and 17.5% sales tax.

The DO version is much more solidly built than my 75-300 IS, which is almost entirely plastic. If it didn't go to 300mm, have IS and come in so "cheap" then I would never have bought it. It feels cheap and takes an age to focus (it frequently hunts through the entire range before settling). It also doesn't have full time auto focus, meaning you can't help it with its focus problems.

But it does do 300mm (480mm in 35mm terms) and I can take decent shots at 1/250, so I love it

Nearly as impressive in the "how did they do that" area, is my wife's new digicam. A 36mm-420mm stabilised lens on a camera that you can put in your pocket and weighs less than any one of my lenses...

If I buy an "import" lens from B&H Photo, generally that means that Nikon USA (or Canon USA, so far as I know) won't touch it. Instead, B&H offers you their own warranty for the same time period and whatnot.

Given how much cheaper it is to buy these things in the U.S., I'm surprised there isn't some sort of arbitrage going on. Is there not a U.K. version of B&H selling "import" gear for close to American prices? If they buy at wholesale (or even street) prices here and pay those duties, it looks like they still come out ahead of your street prices.

Re: Anyone have the Canon SD300 camera? - 08/03/2005 10:47

The DO lens has the "full version" of 3rd-generation IS; the others do not. This adds bulk and some weight, it seems. But the glass in the DO is just plain DENSE.. What DO saves, is length. But it feels very dense and solid (not bad, but a rather good feel).

Seems to work well enough too. But I find the pictures go soft when backlit, such as shooting birds in the sky, or dark objects against a bright background (exposed for the dark objects, that is).

Love it. Haven't touched my 70-200L-IS since I got the 70-300-DO.

I think it depends on your local Canon people honouring the warranty. My understanding is that Canon US will not honour claims on grey kit imported into the US, whereas Canon UK will honour claims in lenses bought elsewhere in the world (but not bodies).

I have never had a problem with the lenses I bought in the US (they were US stock, rather than greys) so I've never found out whether my understanding is correct or not

It is of course in B&H's benefit to sell added warranty whatever the situation is...

I don't know of any UK based companies doing this. Various European companies have won court cases in the past against people under cutting the official European importers of various stuff, which probably explains it.

There are lots of Hong Kong based people who specialise in selling new camera gear to the UK on ebay though. Many of them advertise the fact that they will attempt to package the goods to avoid duty and sales tax.

Well, if you only need to resolve 0.3 Megapixels (640x480), you can hide a lot of lens sins.

I do love the IS on the videocameras tho. I'd never buy one without.

Re: Anyone have the Canon SD300 camera? - 08/03/2005 12:39

Ah, did I mislead you with the word "digicam" ?

I'm not talking about a video camera, this is a digital stills camera with 3 Megapixels. The lens is also f/2.8 for the entire zoom range.

All for 326 g (11.5 oz) including batteries.

http://www.dpreview.com/reviews/panasonicfz3/

Of course compared to my 10D the Panasonic isn't really a f/2.8 lens, because of the fact that its 100 ASA mode has more noise that the Canon's 400 ASA mode. So it loses two stops if you want comparable noise levels, making it more like an f/5.6 or worse. But very neat none the less.

I agree with the noise issues, but the other place this gets interesting is when you compare depth of field. I've been playing with the online depth-of-field calculator. For a 300mm lens on my Nikon D-SLR at f/5.6 shooting a subject at 20ft, the depth of field will be about .7 feet. The calculator says that your Panasonic (55.2mm at the long end) gets about 2 feet of DOF at f/2.8 at the same distance. For a compact camera, that's pretty good compared to many smaller cameras that have huge DOF that you may not necessarily want.

(Random question: why should the depth of field change as a function of the sensor size? If I plug in a 55.2mm lens at f/2.8 on a 35mm film camera, I get 16 feet of DOF. Any idea what's going on here?)

Re: Anyone have the Canon SD300 camera? - 08/03/2005 14:30

I'm afraid the finer details of DOF, hyperfocal distances et al are a mystery to me. What you say matches my experience with the two cameras concerned though.

I suspect that the answer is "it is due to the different sizes of the circle of confusion for the two sensors", which doesn't help much...

Re: Anyone have the Canon SD300 camera? - 08/03/2005 19:51

Aah, I did indeed mistake your meaning! Cool then! I'm still running my trusty old Canon S30 for my wee-rig (when I don't have the energy to move the 10D, or underwater). That looks like a very capable little unit, the Cons in the conclusion page @dpreview all look like pretty minor points. My S30 suffers from a slow lens, and focus is crap in low light, but it's respectable otherwise. Moving from the full size camera is always somewhat frustrating, so I can sympathize.

Re: Anyone have the Canon SD300 camera? - 11/03/2005 15:57

DOF depends only on lens' focal lenght and apreture, not on the ratio of the focal length and size of your sensor. Smaller the sensor, 'shorte' the lens you use for the same purpose; hence, deeper DOF.
Posted by: Ezekiel

Re: Anyone have the Canon SD300 camera? - 11/03/2005 16:31

For the best article on Depth of Field I've come across go take a look at the DOF Article at Luminous Landscape. It explains things in a pretty straightforward way.

-Zeke
Posted by: DWallach

Re: Anyone have the Canon SD300 camera? - 12/03/2005 20:55

Semi-random guess: when that DOF calculator web site said that my D70 had *less* DOF than a 35mm camera with the exact same lens, the difference could be related to the higher resolution of the sensor, rather than to the smaller sensor, itself. According to that Luminous Landscape article, sharpness, for film, is typically definied to be resolving 30 lines/mm (i.e., 60 pixels/mm). But, for the six megapixel sensor on my camera, there are 125 pixels/mm. That means you need a smaller circle of confusion, and thus get less DOF out of the same lens with the same settings.

Of course, high-end high-resolution film can easily top 100 lines/mm, and, following this logic, would have even less DOF because you were, in effect, demanding a much smaller circle of confusion.

Or, at least, that's my understanding now...

Something's funny there.. your D70 ought to have MORE depth of field than any full-frame 35mm camera at the (EDIT:) equivalent focal length and aperature.

Basic geometry there.

Shouldn't DOF be exactly the same for the same actual (as opposed to 'equivalent') focal length and aperture (and 'circle of confusion' used, which is somewhat arbitrary)?

Ooops. Yes, of course it is!

so has anyone bought the SD500 yet? the 7.1 megapixel Canon....

I don't think it's supposed to be out for another week or so.

My SD300 came in today. I decided to go ahead and get it since my total budget was $400 and I wanted a 512 meg SD card and card reader also. That ruled out the SD400. The battery isn't charged yet, so I haven't turned it on. My first impression is that it's...tiny. Definitely smaller than I imagined. I like it. It's actually pocketable.

More to come.

As I read that Luminous Landscape article, it's all about the circle of confusion. For yee olde 35mm film camera, the assumed circle of confusion is pretty big, corresponding to resolving 30 lines/mm. So, the DOF marks tell you how much DOF you'll get with a 30 line/mm resolution. If you're into using one of the high-end high-resolution low-speed films, as I now (vaguely) understand it, you'll have to trade off DOF for extra sharpness. That is, you'll get perfect sharpness for objects that are exactly at the focal distance, but by the time those objects are at the DOF markers, they'll be too fuzzy for your sharpness requirements.

Along those same lines, the assumption of the DOF calculator (for what it's worth), seems to be that the higher resolution (in lines/mm) of a modern D-SLR necessitates less DOF. Or, another way of of saying it, is that the higher-resolution sensor on a D-SLR is like using higher-resolution film, and necessitates a smaller circle of confusion.

I almost think I'm understanding this now...

I think technically you're spot on about the higher resolution, but really when you print things out, most of the time you don't take advantage of all those extra pixels in the high resolution shots unless you print really really large prints, so the argument gets a bit, well, fuzzy!

Which, clearly, is why they call it the circle of confusion.

Yeah, it took me a while to realize it wasn't the circle that was confused!
