comment Disadvantages of electronic viewfinders?
Re "The remaining problem though for MF is lag. Just like the EVF lags action, it lags behind the focus-ring too and on some cameras I find it rather hard to get focus exactly right without back-and-forth movement." -> NB FYI only: On my Sony A77 with EVF I have never noticed manual focusing being a problem. I have high level focus peaking set "as of right". I can disable it but would probably never choose to. | Just had a play in low light conditions - focus ability not noticeably affected by EVF delay.

comment What are the disadvantages of SLT-cameras and are they THAT bad?
The pellicle loss is actually ~= 1/3 of the light but ~= 1/2 of an f stop loss due to logarithmic nature of the calculation. eg 2/3 x 2/3 = 4/9 = 0.444 of original = > 1 stop so 1/3 loss is > 1/2 stop. 1/2 a stop is (1-1/sqrt2) loss = 1-0.7071 =~ 29.3% loss. The difference between 1/2 and 1/3 of a stop is almost indistinguishable to mere mortals. Even a full 1/2 stop loss is relatively minimal as it reflects not in exposure, which is the same with an equal metering in both cases, but in aperture and/or shutter speed used. eg 1/100th of a second would become 1/70th, all else being equal.

comment How do I get over my shyness when taking photos of strangers?
as at August 29 2014 the 100Strangers site has been taken over by an AdServer and the waybackmachine / internet archive declines to provide past coverage. I've changed the link to a site which appears to relate - you may wish to check. Also added a Flickr photostream link for the project.

comment How do I handle international copyright violations?
... I I've got that wrong, my apologies, and you can of course restore the image. [Replace the x by 1 in the above link.] Even leaving the image on Imgur MAY have the sane effect but I'll leave that to you to sort out. This site has your image on it, AND they state that they got it from The NYC department of records

comment Low light photography with lens limitation
Why did you use f/22? Are you aware that that allows an extremely small amount of light into the camera compared to apertures with smaller f numbers = larger apertures?
