comment Why are there no fast APS-C zooms beyond 55mm?
Hi anon, i believe sigma used the 70-200 body for the new 50-150, probably to save costs. One possible side effect of using the larger body is its very, very high performance.

comment What are some of your pre-shoot checklist tips?
Hi alan, the one thing i always take that is not on your great list is a lens cloth.

comment Will a dSLR and compact camera produce the same bokeh output at f/2.0?
Hi andrew, the depth of field is different when using the equivalent focal length and same fstop on a compact, compared to a full frame. The panasonic lx5 at 50mm equivalent field of view (actual 10.6mm focal length), focussing at 3m, at f2.8 has a depth of field of 3.5m. the leica m9, using a 50mm lens at 2.8, has a depth of field of just 0.6m. I have used the lx5 lens spec from dpreview, and the calculator at dofmaster.com I understand your point, but the comparison with equivalent field of view is more practical comparison in real world situations.

ps the linked question you gave gave an answer that explained part of the similarity in build. the front element is a fixed size for a given focal length / aperture, regardless of sensor size.

comment Why are there no fast APS-C zooms beyond 55mm?
Hi Imre, thats pretty much what i thought. But i dont understand where there are so many normal fast zooms of 24-70 equivalent, but not one fast zoom offering the 70-200 equivalent (apart from the discontinued sigma and tokina). the dx equivalent of a 70-200 would be much smaller / cheaper, but i guess seeing both tokina and sigma leave this niche, it is not very profitable at all. Cheers

comment How can I create a smart collection that checks for only *one* given keyword in Lightroom 3?
does this work now with lightroom 3.4? i have set up a smart collection using "starts with" and "ends with" "flickr", and it is returning only those photos with exactly "flickr", excluding a photo that i had with the dummy keyword "flickrzzz".

that makes sense as i haven't seen exposure compensation in manual mode before.
