naththo: Thats very interesting article there. Thats the good thing about less screws etc would have made repair a lot easy but there are some downside you said about hidden screws for grip but you found it near the end though. The top replacement would be harder to put back on as you said. So overall I would say in difficulty skill to be quite difficult, not as difficult as disassemble and re assemble main DSLR. Thanks for sharing with us. I am glad Sony stick to the way to make a bit easier than iphone for example.
"yeah right, you will repair this camera yourself, sure!"
Well, I doubt it would be covered by the warranty now!
Shame about the dust.
rfsIII: The only criticism I have is that you shouldn't test lens distortion by taking pictures in a city that's more than 2,000 years old.
So many of London's buildings are beyond ancient and the rest are built atop the unsteady debris of thousands of years of human occupation; I cannot imagine that there is a straight wall or level floor anywhere within that venerable metropolis.
What you see as evidence of "severe" barrel distortion is more likely just a medieval wall bowed outward by the relentless forces of gravity and time.
Too big, and too heavy!
