Default Keep 70-200F4 or swap to F2.8

Ok, so I am in need of some longer range (than my 85 F1.8) internal glass (kids in Gymnastics). From where I can be, I will be at 200mm 90% of the time. I will also be shooting my kids in Soccer (primary task) (under 8 league). I have a 70-200 F4 non IS. the two alternatives I have been kicking around is picking up a longer prime (135 F2 or 200 F2.8) for the gym or trading the F4 for a 70-200 F2.8. my issues with the trade is that the 2.8 is much heavier and I love the F4 for most things. Long term the F4 will end up getting traded or added to for something longer (120-300?). FYI the body is a T2i

Tough question. As the kids get bigger, they will grow out of the 70-200mm. But as the kids get bigger, they might grow into the 85mm. Is this your kid? or kids? For small kids in gymnasics, you should probably get something longer that the 85mm. The 100/2.0 isn't a big step (17%), and while the 135/2.0 is (58%), it also costs a lot more.

From what you say, the 70-200/4.0 probably doesn't have much future with you, and the 70-200/2.8 will do the gymnasics now, and the soccer now. But somewhere along the line, you'll probably need to get something longer for soccer.

The 50-150/2.8 that shoturtle mentioned might do as well for the gymnastics, but not for the soccer, so you'd have to keep the 70-200/4.0, so no trade-in.

You can add the 1.4 TC down the line for the soccer for shooting wide open with the 70-200 later down the road. And it should work for the sigma 50-150 also.

With the gymnastics you will probably find that f2.8 is still too limiting regarding shutter speed. Most gyms we have to shoot gymnastics in are not great at best, to get the shutter speeds I would like for tumbling (1/800s + you need f2 and ISO 6400. Yes you could double the ISO but noise is still not great at these numbers). So that means 135mm f2 if you really need such reach. It depends on your access. I only shoot gymnastics as a photographer not as a parent so can get closer which means the 85mm f1.8 on a 1DmkIII (1.3x crop) is long enough for speed work, then for longer shots I will use the 70-200mm f2.8 or 120-300mm f2.8 depending on requirements.

Now with soccer, as has been stated 200mm is OK for now but soon you will find the limits of that length. So basically there isn't a single solution, this is why most of us who shoot sports have heavy bags to carry our kit to cover the lenses we need. Go with what is most important first rather than trying to cover everything off as unless you have very big pockets it's not going to work. The one lens that might do it all if you can't get close in gym is the 200mm f2.... now put a 2x TC on there and you have a 400mm f4 and I want to be your best friend and borrow it lots!! You might need to sell a few limbs or something to get one, then hire someone strong to carry it for you too LOL.

Yes these are my Kids one 7 yrd old Daughter and A 3 yrd old son (started late as I am 51). Yeah I am figuring that the future holds the 120-300 F2.8 (at least)in a couple of years (save up the bonus money). The issue with F2.8 not being enough for the Gym is one that has been bothering me. I am thinking I will end up with a 135mm F2 for the short term. The 200 F2 is way out of my league!

For the age of the children currently then I think f2.8 will be enough in the gym as things are happening slower, but as they get older that will likely change. If you get the 135mm f2 you won't ever want to part with it, simply stunning lens, so many times I've almost added it to my kit but never quite been able to justify it. As for the 200 f2, it's out of most of our leagues, but boy wouldn't it be nice to own. If I had that I would change my signature to show my camera kit so I could show off LOL.

The 135L is a great lens. Well worth the money, but as you will be shooting a prime. There may be times you are to tight and can not back up far enough. Just something else to consider. I favor primes, but they do have some limitation as well.

Yeah I was shooting the 85 F1.8 on vacation last week (dark cave) and it was different. There was a guy with a D90 and a kit zoom taking in the same place (no flash allowed) and he must have had it on auto as the flash popped a couple of times. He looked over at me shooting without the flash and tried to figure it out. I showed him the lens and a couple of shots and he wants a fast prime now.

Yup, primes are bright, but to cover the ranges, you need a bunch of them. I have a 28 1.8, 50 1.4, 85 1.8, 100 2.8 macro. I would like to get the 135 2.0L, but it I can not justified the cost for it. To bad they do not have a no L version at say 2.5.
