I am working with a budget of $2000. I currently have a 40D with an UWA lens (bought for a trip) and a 28-70 f/2.8 lens on it. Recently I have been working on doing candid street portraits and posed street portraits with limited lighting (one or two off camera flashes). I am really excited about this project and am working on composing a way to display all of this work. This is mostly a hobby and the only time I sell is per request. Anyway... I have been looking at web galleries of this sort of work and I see that most pros use a full frame camera and a prime 50 or 85 for this sort of thing. The biggest thing I have trouble with is controlling the depth of field. I usually zoom out to 75 and shoot close to wide open. However, I'm not getting the bokeh effect or depth of field I am looking for. My goal in shooting is to capture what intrigues me about each subject... Could be face, full body, partial face... There are some zany people out there that are so incredibly interesting to photograph it is impossible not to... I usually only get one or two shots per composition is to focus on an interesting aspect of my subject Two part question: Should I keep my 40D invest in a 30 f1.4 prime, which would be similar to the focal field of a 50 f1.4 on a full frame and call it good? I rarely ever use the 6.5fps the camera is capable of (as a side note)... I think I will be shooting street portraits and candid scenes for quite awhile so I am strongly considering my other option: Sell the 40D, UWA, 28-75 and start over with a full frame and a prime 50 1.4 and 85 1.8? If I go that route, for what I am doing, what are some good suggestions for hardware: 1ds mark I 5d mark I Nikons, or other? Again, $2000 budget, high quality lens older full frame camera? Or... Not to muddy the water too much... Bite the bullet and buy the 50mm 1.2... Hope my convoluted questions can be answered on this forum! One of the best communities on the net!
