hi phinix
if you want to shoot bugs,i'd recommend a focal length of 90mm and over...to prevent scaring them as the working distance might be a little close with a 50mm lens.extension tubes only exacerbate the working distance between subject and lens.i realise the longer focal length macro lens are pretty expensive,but it might be worth saving a while longer to get what you require,rather than buy something you may regret getting sooner or later
Hi Stan,
thanks, see, thats the point - you're right and I forgot to mention what I want to shoot. I hate bugs
What I'm looking for is flowers macro, so other "dead" subjects
Also PC parts and stuff. Other thing I wanted to "suck" form this new lens is portraits. I have a little daughter and portraits from kit lens are not that beautiful as I want. Of course I'm not pro, just learning how to use dSLR. I bought my A300 year ago and after that year I feel like I need something else than just kit lens... I want to explore more and that is why looking for new, but not expensive lens.
I can see another problem here - not many people use Sony equipment, so I may not find any
second hand lens that quickly that I may need.
I could go for Sigma 17-70 and sell kit lens. That Sigma has macro option, 1:2.3 so that would be enough I think for flowers and pc parts. Portraits would be good as well I believe. However the long end has 4.5, so constant 2.8 would be better, cause I do a lot photos indoors as well... Then Sigma or Tamron comes on top - 18-50 or 17-50. Tamron however doesnt have macro option. Then there is another thing - I want really sharp lens, and to get that I believe I need to get prime lens....
So I decided (not for 100% yet
) to buy a prime 50 or 90mm for macros and portraits with constant 2.8 and have fun with it, later, next year or so try to sell kit lens and then get sth better, like Tamron 17-50. I don't think that I need a longer lens, but I believe 105 would be fine. But that is a longer story
