While the world is talking about shutter shake in some mirrorless cameras, some manufacturers even releasing firmware hacks to make it less of an issue. Guess what, cheap shutters and low mass don't work so well.
Who knows what else will happen?
Well, shutter shock affecting the image is a little more complicated than that. IIRC, objects have a "resonant or natural frequency" that relate to size and mass. If the object is above or below that mass/size sweet spot, than the effect on the object is less.
I remember a report that Falk L. did on the K7 showing it was subject to shutter shock somewhere close to 1/100s shutter, but that is just a guess since it was a few years ago. Then recently i read that the D800 had shutter shock and the D810 was designed to reduce that problem. Then i read about another camera that might have the problem, so i've come to the opinion that it is more prevalent than we might suspect. But it only affects a specific shutter value area. And it can be minimized by reducing the shock transferred to the object back in the design stage.
Originally posted by mecrox Good points. My next camera will highly likely be a DSLR because of the lens support on Pentax, Nikon and Canon, the three brands which make them. But one looks at the market - Asia + Japan dwarf other regional markets, MILC sales climbing in Asia and Japan and now in Europe, DSLR sales turning down somewhat and anyway dominated by a hegemony, etc. - and it's not hard to think the camera-makers will want to direct their portfolios to what sells and where in the world. So I guess there may be less attention paid to what we want over here in the West which is still more focused on DSLRs than the East. (According to the figures; the reality could be different of course when we come to look back on 2013/14.) Even the USA, which is an economic superpower, takes only about a quarter of the DSLR output and half that of the MILC output worldwide.
The fact that Canikon and Pentax have the good lenses, but are not so interested in MILC frustrates me. But hey, its not a perfect world, and thats the way it is. I suspect that both types of cameras might coexist for some time to come - each with its pros and cons.
Originally posted by Big Dave I haven't tested the DA 55-300 yet, so I don't know how it dies in the corners on FF. It dose cover the FF at 55 mm and as you zoom out the image circle will increase, masking any flaws at 55m, if any exist. You will need an adapter with aperturs adjustment on the Sony.

My Pentax DSLR's are given to my adult children. Everybody has one now and they are all going strong for many years. I use my K5 II and Sony A7 and I haven't had any issues. I guess I am just lucky. By the way Sony parts and accessories aren't cheap.
So where do you use the A7 in preference over the K5 II? And what is your most frequently used lens with the A7? I'm still thinking about the A7, but am not sure i would use it that much if i had it. :-(
