Most FD->E adapters have an open/close ring that makes them function as presets: you set the desired aperture on the lens aperture ring, and then twisting between open and close on the adapter's...

The EOS-M does produce "Canon colors" in JPEGs, which are technically no better/worse than Sony, but are different. Canon also has been very consistent over many years of camera models, whereas...

Well, I'm not crazy about zooms nor AF, but I'll play along here.... I have a beercan, and it works very well on the LA-EA2 (the SLT adapter). So does my Sigma 28-200mm, etc. The beercan is just...

The potential issue is masking/clipping of the exit pupil. The Sony LA-EA1 and LA-EA2 both contain internal masking that is probably a problem. It should go without saying that focal reducers and...

I don't have a 3n, but the NEX-5 is the first Sony mirrorless and this is Canon's. Seems fair to me either way. Don't have many to compare, but my two copies of the old Sony kit zoom are very...

I'm disappointed there are just 3 entries, but they're all good -- and good examples of why wifi remote capture is useful.

Maybe not yet. You're forgetting development cost. However, mirrorless wins on cost in the longer term. The A3000 pricing demonstrates how sharply mirrorless cost drops when you get to use...

Never say never.  ;-)  I said it would be a very bold move. It also is worth noting that Canon actually has been making lenses in somebody else's native mount.  As DPReview reported, Canon...

You know, when I first saw the EOS-M that was my impression too. However, the sensor in the EOS-M is not much worse than the best 1.6X crop sensors Canon makes... it's just that isn't very good...

Some ultra-high-resolution wide-angle surveillance camera sensors are round (or stitched from a roughly round collection of smaller rectangular sensors), and some were round even using film. The...

I don't have the 22mm, but I can see where that might be quite endearing. I have happily shot with various manual lenses on the EOS-M using Magic Lantern (and ML is great and there is nothing like...

You know, I've just about given up on SAR. I don't think it's their fault -- I think SAR is getting jerked around as Sony feels out the market and deals with shifting production schedules -- but...

Well, I'm not sure I dare post this in the Canon forum, but I've been playing with an EOS-M under Magic Lantern for a while now, and figured it might be worthwhile to say a little, given the fire...

Why would they move the EVF?  Well, the sensor is bigger... but the best reason I can think of would be to make room for the IBIS sensor mount, which is significantly wider than the sensor in Alpha...

Yes, gain is applied after the integration period ends (with or without a shutter); I wasn't referring to something like adjusting the quantum efficiency, which is impractical if not impossible....

I had not.  Great site!

ISO film speed is a bit of a judgement call for sensors used in digital cameras. Basically, the notion of ISO change is implemented by two things: Change of the exposure settings (aperture and...

9 microns? In a word, no. The emulsion itself of many films is thicker than that. Of course, most 135-format films people used didn't deliver come close to the resolution of my 24MP APS-C NEX-7. As...

Fundamentally it is that deconvolution, although computationally cheap, isn't quite the right algorithm.

Three major issues. (1) Rays coming in through different portions of the lens are actually...

No, the tiny sensor crops. A micro4/3 sensor is about 2X crop, so field of view of a 50mm lens is like that of a 100mm lens on a full frame camera.  APS-C sensors (e.g., Sony NEX) are 1.5X crop.
