Hey all,
Looking to add a 70-200 to my Canon kit again, had one in the past, as the kids are getting older and we do more outdoor sports. But, I'm curious what I should really lean on. This is just family and friends outdoor youth sports, like track, soccer, softball, etc. The camera it'll be bolted to is my Canon 1D Mark III. I was at a youth track meet with my daughter and I have a 300 F4L and Tamron 150-600 but those were way too long for youth track, so I had my 50mm F1.8 on my 1D. Yea. It was funny looking, but it's the only non-long-lens I have for Canon anymore. So, maybe it's time to add a 70-200 back so I have an option. I generally like primes, but this is likely where a zoom truly will be needed. I know I will want that 70mm side sometimes.
So that has me thinking.
I went through a lot of flickr pools, looked at sample threads, etc. But ultimately I wasn't able to find much examples of what I'm curious about. So I'm hoping to maybe find a few friendly souls who can share something specific.
I'm debating between F2.8 and F4. Part of me wants to get the F2.8. Part of me wants the F4 to reduce size, cost, weight, etc. I'm also debating... Canon or Tamron for this. Mostly though, I'm looking to add a used lens only, nothing new, so I'm also looking at the older lenses. This has me of course comparing the older non-IS F2.8 versions to the IS versions and the older F4 to the F4L IS versions. And then where the older Tamron F2.8 with VC fits into things.
I've seen plenty of samples of outdoor sports, etc, on the 200mm end of these lenses at F2.8 and F4 and they're pleasing either way, 200mm at F4 is fine, enough DOF to get good focus and still enough isolation to soften otherwise potentially crude backgrounds of gawking people with their cellphones, etc. I'm sure you all know that too well. So I feel that on the long end of things, I don't quite care about the difference of F2.8 and F4 in terms of the DOF and it's more about the light. I'm not without light in Florida, so I think I would be ok at F4 anyways. I'm also not at all afraid of high ISO usage. None of this will be used for anything other than sharing with family & friends anyways in smaller formats.
What I'm having a hard time finding are good examples of sports, etc, at the 70mm side of the lens, at F4 and F2.8 to see the difference there. I feel that it could be the deciding factor on which direction to go. Then again, maybe I need F4 for the DOF so I don't miss focus as they get closer and closer with my aged 1D Mark III. Though, these are kids, so not like it would be truly stressing the system.
Would love to see any 70mm F4 and F2.8 comparisons of sports.
Would love some advice or comments with some experience on this.
Currently considering Canon's 70-200 F4L IS (size, weight reduction, decent IS) and Canon's 70-200 F2.8L non-IS (just for the sharper F2.8 as I'm reading a lot that the version with IS is less sharp wide open) as options, used, and gently looking at Tamonr's 70-200 F2.8 VC but not the newest versions as they're expensive even used. Not considering $1k lenses. Looking at those $600 used options mostly (USA).
Very best,
