I have done lots of research and read thousand of posts and reviews which leads me to want to acquire the following lenses.
First tho I would like to explain that I want to experience all types of photography including but not limited to Architecture, Landscape, Macro, Portrait, Sports and Nature. My emphasis is probably more nature sports and architecture, although I love macro as well.
I have a t1i with the kit lens and have purchased a EF 100 F/2.8 Macro USM.
At the top of my list are the following;
1. EF 70-200mm F/2.8L USM, FM rating 9.8, priced new from $1220 and used @ $800ish. Pros-Low light fast focus and sharp. Cons-Bulky and no IS.
2. EF 50mm F/1.4 USM, FM rating 9.0, priced new from $360 and used @ 320ish. Pros-Sharp,lightweight, compact, value and Bokeh. Cons-Build,motor issues and Wide open focusing.
3. Tamron AF 28-75MM F/2.8 XR Di LD Aspherical (IF), FM rating 8.7, priced new from $460 and used @ $350ish. Pros-Sharpness, contrast and value. Cons-Build AF-issues.
4. SIGMA 12-24mm F/4.5-5.6 Ex DG Aspherical HSM, FM rating 8.7, priced new from $750 and used @ $500ish. Pros-Sharpness and build. Cons-Slow focus and heavy.
OTHER HQ LENSES:
EF 70-200mm F/4.0L USM - may be the best value but I wanted more speed.
EF-S 10-22mm F/3.5-4.5 USM - highly rated but price and build are a concern.
EF 24-70mm F/2.8L USM - highly rated but heavy and pricey.
EF 100-400mm F/4.5-5.6L IS USM - highly rated, this lens covers a lot of ground and is lightweight but @$1600+ I am concerned that it may not get used. It is also not a low light lens.
EF 28-300mm F/3.5-5.6L IS USM - highly rated but very expensive $2400+ has great IQ and range but is not a walk around lens.
Since I am trying to get back in to photography after 25+ years away, I wanted to get some experience with many different lenses rather than focus on a few. Also, although price is somewhat of an issue, quality and value were more important. The way I figure it, I can always sell and upgrade if I need to.
Finally, should I be more concerned about the body? What do you FF guys think? In deference to Nikon, Pentax and Olympus, I have already gone down the slippery Canon slope.
Please comment and critique my thinking.
