PowerShot Cameras / Re: Canon Announces the PowerShot S100

One [undoubtedly stupid] question: what does HS stand for?
Hybrid Stabilisation.

It is the newest form of Canon's IS technology as introduced by the latest 100L macro lens. You're referring to Hybrid IS (H-IS) in the 100L Macro, which corrects for angular motion like traditional IS, and for translational shift. There is no system in PowerShots that corrects for translational shift.

HS = high-sensitivity, and refers to the combination of sensor technology and Digic image processing that allows for cleaner (relatively, at least) shots in low light conditions.

I think the S100's macro/hybrid IS mode is designed to correct for shift-type camera shake.

For some reason I just glommed on to the fps. Assuming they didn't make a major change to the internal bus, 3fps sound about right for 32mp. What seem really cool to me is that the 7 and 9fps number work out just about right for cropping to APS-H and APS-C equivilents. Obviously they could also be talking about the difference between a large, medium, and small raw output that doesn't crop, but stays full frame on a effectively smaller res sensor. In theory we could be looking at 9 options...large/med/small for each of full/aps-h/aps-c.  That would make it a first rate replacment for both the 1d and 1ds. The only problem is they would need some internal optics to magnify the image in the viewfinder so you would see the effective crop through the lens. Nothing about the design suggests this.

Sorry, I know I'm a bit new here to be speculating so wildly, but the info is just so suggestive.

I would hope that with new dual Digic V processors, a new 1D series DSLR could process shoot faster than 3 fps at full resolution. Heck, the current 7D does 18MP at 8 fps (144 MP/sec). 32 MP at 3 fps would only be 96 MP/sec. Processors have advanced in the years between models. I would expect significant performance improvements. 32 MP at 9 fps doesn't sound absurd to me.

Signed up to put in my two cents on the wish list.  In order of priority:

Video autofocusing.
Significantly better DR by least 1.5 stops.
Very clean images at high ISO's.  Perhaps 4 stops better than we have with the 5dII.
Better autofocus
>5 FPS
Slightly more resolution, but not at the expense of the previous high ISO performance or DR requirements.

I would pay much more than a paid for my II to get it, and I'm sure I'd have to.

Your wish list is similar to mine, RSBJ, but I don't think 4 stops better at high ISO is going to happen any time soon. It may not even be within the realm of physical possibility given the quantum nature of light. My rough estimates put the top DSLRs currently on the market within about 3 stops of an ideal sensor limited only by photon shot noise. (No, I don't have any references handy for my back-of-the-envelope calculations.) I'd love to be wrong though. High ISO performance is vital to my needs.

Oh god, the flickering lights. How I despise them.

I shoot gymnastics on occasion and need about 1/400 sec. exposures to freeze the movement (slower or faster depending on the event). With the lights cycling at 60 Hz the colors and exposures are all over the place. Flash is never allowed at competitions.

I tend to shoot wide open with a Canon 17-55mm f/2.8 on my 7D and the ISO is often over 3200. I plan to get the 5DIII if/when it arrives (and maybe shoot more often with fast primes) for optimal light gathering capability, but there is nothing I can do about the damned flickering unless I shoot slower than 1/60 sec. and deal with bad subject blurring instead.

I want a state of the art AF system, with 4 fps and 25-28 MP.

The 5D was originally meant for portrait/wedding photographers and the 5DII added better noise control, video, somewhat better AF and a few more MP. But it is still a portrait/wedding photographer's camera. I want it to remain as such and do not want to pay for weather-proofing, dual card slots or 6-7 fps. Leave these specs for higher end cameras and give us a state-of-the-art AF system.

No dual card slots? I would think those would be great for wedding photographers. If one card goes bad, you didn't just lose hundreds of irreplaceable photos.

Because i would find it wery usefull if they did. I myself have a 17-40 and would find this zoom range 50-150 very useful indeed . So the next thing would naturally be a 150-300 f.2,8 L is zoom.
If they could make suche lenses. Im sure these two lenses would be very compact.

How in the world can you get fast tele-zooms that are "very compact"? A 150-300mm f/2.8 L would be a big white monster.

They'll probably stick to compact flash like all the other pro-level DSLRs. I'm hoping they put in a second slot for SDHC cards, but I have no idea if they'll implement something like that or not.

Regardless, what the MacBook has built in is pretty much irrelevant. Decent card readers are relatively inexpensive.

Lenses / Re: Using EF-S lens on FF body???
« on: May 31, 2011, 12:23:03 AM »
To get around the mechanical issue, couldn't you just use a short extension tube designed to accommodate both EF and EF-S lenses? You'd lose infinity focus, but I would think it would work other than that.

I don't understand why the burst rate is so low. 7 or 8fps would be glorious.

pushing 32MP is a lot of data, so burst rates that high would be pretty tough.

A higher burst rate could be accomplishing using dual Digic V processors like the 7D uses dual Digic IV.  This is how the 8 fps burst rate is achieved in the 7D.  Even so, the 5D is primarily a landscape camera so burst rate is a much lower priority, whereas the 7D is a sports/widlife camera where burst rate is much more important.   

At 32 MP they could implement an 8 MP 2x2 pixel binning mode. Even if shooting in full resolution is only 4 fps, with pixel binning they could easily push it to 8 fps. That size and rate would be perfect for me when shooting sports.

Wow. If they do make the sensor 40 MP, I hope they incorporate a 2x2 pixel binning mode for nice 10 MP files when one doesn't want enormous images eating up card and disk space so quickly.

Is anyone else not happy about Canon packing more mega-pixels in?

Low light / high ISO performance is way more important to me than adding (what are in most cases) superfluous pixels.
