Hi guys, first time poster here, but i wanted some advice.
a few years ago a bought a 30D kit from B&H that came with a 17-85 HSM lens. Wasn't the best lens, but serviceable. Also bought a 70/200F4.L at the time, because i liked taking airplane pictures. A few years later i sold the 70-200 and got a 100-400L, needing the better reach for my airplane hobby.
Last year i bought a new 7D, and i have loved it so far, especially with my 100-400, but the 17-85 is probably seeing the end of its useful life, and i'd like to find something else.
I was thinking it would be time to get some L glass for my everyday use lens, but i don't really have a spare $1500 sitting around. What i do have is this 100-400 lens that is still worth quite a bit (at least until the new one comes out)
considering selling that, buying an 24-70 F2.8L (version 1) or a 24-105 F4, or maybe the new tamron 24-70. and perhaps a lesser quality long reach lens for airplanes. I'm always shooting in good light, but focus speed and accuracy is a big deal.
Was wondering if anyone has had any success with sigma/tamron/canon non-L lenses up about the 300mm mark? Would i regret not having the L for my occasional plane spotting?
