Hello,
Newbie here who needs advice as I bunked off my photography course far too often as a teenager and cant remember a thing, except that the darkroom smelled divine and that the teacher gave me a long lecture in why digital photography would never take off. Anyhow I have a Sony a300 and need a wide angle lens to take good quality photos of rooms specifically (Im an estate agent) Im quite happy with the camera and dont want to spend too much money and Im hoping as it is an old model there should be a good deal somewhere on a 2nd hand lens but Im a bit stumped as to which size/model I should get. Any ideas?
Thanks!
 
sigma 10-20 4.5 - 5.6 is what i have, its decent :)
tamron 10 to something and tokina 11 to something are other options
 
two :) a77 and a55, and a dynax 5
www.dyxum.com has a bunch of reviews. id suggest a tripod thats robust aswell, so you can use iso 100 + f11 indoors to get really good depth of field :)

It depends what you want acceptably sharp, what focal length you're using and at what distance from the camera your first object is but if your first object is, lets say... 4 ft or more from the camera and you are shooting at the wider end of the zoom range you could use f4 and still get DoF from just over 3ft to infinity. At the longer end of the range, maybe 20mm, at f11 you'd get DoF from just over 3ft to infinity but if your first thing is 5 or 6ft away (that's possible) you could maybe shoot at f5.6 to 8 and still get adequate DoF to infinity.

But for indoor shooting why would you need DoF to infinity? You could probably shoot at f8 or even f5.6 and get DoF from a few feet to way beyond the size of a room or even a whole floor.

At f11 you'll get deep DoF but you'll possibly suffer more nasties associated with smaller apertures. That may or may not matter in the final image but personally I try to use apertures that are merely adequate rather than overkill. Just a thought.
