Hey guys, I could use a little help picking a lens. This will be used on a 1d mark ii n (occasionally a 6d, maybe on my gh2 down the road). Right now, I have a helios 44-2, and a pentax 200mm f3.5, but my mom has the 16-35 f2.8L II and the 70-200f2.8L which I can use (with the 6d) when I am home. This is why I am not considering a 70-200, as much as I love the range, with my current setup, I feel like the money could be spent better in other places. Anyways, my budget is roughly $500, maybe a little more (absolutely not over $700). I am fine buying used. It will be used mostly for taking pictures skiing (racing and freestyle), and then possibly some paid things on the side (I really like doing panoramas, and I may have some potential work doing portraits or action sports photography). Currently, i am looking at the canon 200mm f2.8 (I or II), the 85mm f1.8, maybe the 24-105 f4L or 300mm f4L if I can get a deal (I think the 300mm may be a little long and out of budget). Open to any reasonable suggestions.
Just the facts
APS-H (1.3x crop)
have 2 manual vintage lenses, access to 70-200 f2.8 and 16-35 f2.8
want it for ski photos, maybe some portraits, and I really like to do panoramas
$500-$600 budget, used is fine
