comment How wide can a lens be before it begins to produce distortion?
Great answer. Only I would add something to address the 'fisheye' part of the question: Fisheye lenses are not simply very wide lenses, they use a different construction that turn straight lines into curves when not passing through the center of the frame. A perfect fisheye lens would still do that while a perfect rectilinear would not (although there is no such thing in any case).

comment A website that can help me in choice of new lens?
How important is minimum focus distance instead of magnification? And how about number of elements/groups? My site (Neocamera) offers other criteria and many more, as someone already mentioned, but I did not think those were important enough to crowd the interface.

comment Should I choose Hoya HD CP or Nikon CP II polarization filters?
Never seen a Marumi filter and I don't have the technology to scientifically measure one but I can vouch for the Hoya HD filter. I was already happy the their Super-Multi-Coated but the new HD one is even better. Both show no color-shift (unlike B+W which I got rid of) but the HD is crisper.

comment How do I find the right size of filters for a lens?
@Mattia - Here's my citation 'polarizers reduce light by between 2 and 2 1/2 stops'. I can put it my website to make it official ;) If the meter does not change, your images would come out quite dark. Perhaps if Auto ISO was on, then you did not notice the camera compensating.

comment Is there a way to search by aspect ratio in Lightroom?
Thanks! Guess it depends on priorities, I really do not mind searching for a specific lens (10756 of my images match 'Unknown lens'), but finding a photo that fits is very important to me! My images are cropped very tightly in-camera (can't work without a 100% coverage viewfinder anymore) so I can rarely simply crop an existing image to fit a requested format.

Just a note that instead of searching for cropped images, which you can't, you have to create a Collection which selects cropped images for you. That is pretty simple to do.

comment Scanners with large depth-of-field?
Have you tried the HP Scanjet 4670 See-Through scanner? It is supposed to let you take pictures of objects by simply placing the scanner on top and as such is not expected to be perfectly level... I can't confirm this though, only that I read it somewhere.

comment Do point and shoots exist which can get close to what DSLRs can produce? (And where could I find one?)
Canon G-series are only marginally better than most point-and-shoot cameras in terms of image quality, so recommend removing those from your answer. Same goes for the Nikon P7000 which you did not mention. There are a few similar models with have bright lenses (Olympus ZX-1, Canon S90/S95) that give then another incremental advantage. Still, large sensors of 4/3rds size or more are the only ones to compare with DSLRs.
