You only know the transfer function of the image itself. But the sensor noise gets added after the lens, so it gets boosted by the de-convolution. In other words, the lens damages the dynamic...

A blurry lens causes irretrievable damage to the information that was gathered. This loss manifests itself as a bunch of noise in the corrected image. All this software does is let me trade off...

You need a step-up ring.  I'm using a 40.5 to 52mm step up adapter which I leave on all the time.  It's a nice size for a polarizer because it roughly matches the barrel diameter of that lens.  I...

I have the 250 and I would recommend it.  It'll let you get alien-world like magnification at 210mm and more conventional magnification in the 55-100 range.  It also allows the 16-50 to get great...

It is, but I think Sony is more-or-less using that brand properly which is to say their Zeiss lenses are well-specified, perform well on lens tests, and even perform well in areas that aren't...

Because it's the standard by which some people judge the approximate FOV of a lens. I personally find it not useful for APS-C since that's what I'm most fluent in.  But for cameras whose sensor...

Sony is making actual DSLR cameras (or at least they were until recently.) I suppose the salient difference with the A3000 is the price point.

We were talking about camera bodies. The difference in lens sizes between m43 and APS-C is negligible as far as material cost or tolerances are concerned (APS-C is slightly more material, m43...

How do you know this? Making things small is difficult and expensive--this is a disadvantage of the smaller form factor. Certainly Panasonic and Olympus' reported profits don't suggest they're...

m4/3 is safe as long as Panasonic and Olympus can make money doing it. So far they aren't making money and neither is Sony. But Sony is doing something to try to change that.

PeterTom, there is no "mirrorless" market segment. There is a low-end-DSLR-body-style market which is what the A3000 appears to be targeting. By the way, making the camera bigger and deeper is a...

Seems like a different market. I have a hard time believing the Rebel/A3000 market is interested in the OMD (any more than those same people were interested in the NEX-6/7). Those people are...

qwertyasdf, people want what they want. Can't fault Sony for trying to give them what they want. Besides, I think it's an excellent strategic move. Assuming it performs, it'll serve as a gateway...

Oh that lens will be fine.  My Pentax 12-24/4 + adaptor weighs more and all of the weight is at the end and it feels fine on my NEX-6. Fitting in my bag is another story--the 18-105 has a 72mm...

It's comparable in quality to the Sony--nice tight fit. The 52 is a new design for Metz--much nicer IMO than the previous gen 58 (I reckon Metz will have a new gen replacement for the 58 soon.)...

The Metz flashes all support the full wireless system according to the manuals. I got the Metz 52 for my NEX-6.  It has the servo mode so you can even wirelessly trigger it (manual flash) from the...

This would be the best feature addition IMO--use the pop-up flash as master or controller. Along with that, if they added a manual setting for the popup flash, that'd be nifty too (and this should...

I also owned the 17-70 and I agree that it's a good lens, but not great.  Plus it was large.  So an NEX lens that is both smaller and sharper is certainly worth more money.  If it came out at...

I'd love it if this were true--then those low cost Sigma primes and Alpha telephoto lenses with adaptors suddenly start to interest me.  Although they also need a dramatically improved auto-focus...
