comment Why do small sensor cameras use proportionally larger mounts?
Checked not so much but it looks awfully small to me. The rear elements of the two Nikon 1 lenses I have here (10-30mm and 30-110mm) is there small. On the 30-110mm it measures 1cm diagonally.

Sorry but I do not think this makes much sense because the lenses are designed for the smaller imaging circle, so the only thing they can keep of the system is the size the the mount if they change the sensor size.

comment How can I maintain high resolution when converting RAW images to tiff or jpeg?
@Susan - Do not resample, just copy it into Illustrator as is. As I said, even the D3X does not reach the resolution, you would need a medium format camera cost about $10K plus lenses to get that. The requirement you state is artificial.

Now that I read the part about Illustrator, it makes even less sense what you are asking. You will start getting artifacts from multiple layers of resampling, do the sizing in Illustrator and render the final output to whichever DPI is asked of you.

Yes, that is resampling which makes software invent pixels. That is why you should avoid doing it. It would be much better to send the file as is and ask for an 11" high print. The printer will do its own resampling then to satisfy its internal requirements which is probably not 600 DPI anyway.

comment Why am I getting soft images with my Sigma 24-70 f2.8?
Check the aperture of the soft images. Just because you lens can do F/2.8, it does not mean it is usable. I found that with a number of Sigma lenses (did have that one though) and would only use them at F/4 or smaller, meaning I only ever could use A, M or TAv modes.

comment Are there any mobile applications that calculate sunrise/sunset based on location?
Sundroid is the one I use. All I can say it that it works and has a free version. I cannot tell you how good it is because that is the only one I tried.

comment How to shop for a lens filter?
B+W filters are not color-neutral. Particularly their polarizers cause a brownish shift. Their UV cuts too early in the violets. It is noticeable directly in the VF. So I sold my entire set of B+W filters which were top-of-the-line. I have the entire range of Hoya Polarizers and several UVs without any variance in color or space. Hoya HD filters are a level above ALL filters I tried with the polarizer showing +1 EV of transmission.
