I will remember the sigma, it looks good. In your opinion, how big a difference is there between f/3.5 and f/2.8? Is this something very noticeable?
Sorry for getting back to you all so late, have been very busy and then also some sad news, we had a miscarriage, but we know that it is something common so we are trying not be too sad about it.
We went through this 4x, but we do have one child, now 25, and in her last year of graduate school, still a child, but approaching adulthood. Persevere my young friend.
I think your question about f/3.5 and f/2.8 depends on the lens. If you are looking for a prime lens generally wider is better. At f/2.8 you can shoot indoors and it will be rather tan. I suggest an aperture below 2.0 for indoor shooting. If you are looking at prime lenses with these and have any desire to take indoor shots invest in a flash. I bought a Yongnuo Speedlite YN585EX, it is amazing how well it meshes with the Pentax equipment and in auto-mode helps give me such good indoor photos. The pop-up flash on the K-5 will blind everyone and overexpose everything.
