I shoot my son's football and baseball games and have really enjoyed the quality I get with the f4 (without IS). His games are duing daylight hours.

However....I would like a little more length so I am considering upgrading to the 2.8 (without IS) and using the 1.4TC. Also thinking I would have a fast enough lens to help when he starts playing under the lights.

2 Questions.....

1. If I am happy with the quality I am getting from the f4, will I also be happy with the 2.8 and 1.4TC?

2. Is it reasonable to think I can get $400 for my f4? It is very good condition. I would say like new. I think I would keep it for anything less.

I think you could get a few bucks more for your f/4. I got $450 for mine. For anything less than $400 you should keep the one you have. The 70-200 f/4 is way sharp. I had one and sold it for the 70-200 2.8 non-IS I have now. They are the same sharpness. But a 2.8 will go 2.8 and an f/4 wont. Youre gonna lose a whole stop with the TC (IIRC). The rest is up to you.

I can only answer #2, it's probably going for around $500-575 right now, so I would say yes, and canon prices are increasing also.

Try the TC on your f4 first because you may find you will want IS at a longer focal length.

Thanks. I may sell it on this site. They seem to go pretty quick.

Would love to hear feedback from anyone that has used the 2.8 with 1.4TC for sports during daylight hours.

Thanks. That's a great idea. But, the way I understand IS, it is useless when shooting moving objects anyway....right? I really only use the lens for sports.

the 70-200 f4 with 1.4x is still very very sharp!

I wonder if I can keep my shutter speed > 1/1000 to freeze the motion if I couple the TC with the f4.

I guess there is one way to find out. ;)

What ISO are you currently shooting at? You could always stick the 1.4x on the f/4 and bump your ISO up a stop.

Id get the 2.8, But you could always test the 1.4TC on the f/4 and see how things look.

I may go as high as 800 on overcast days. It gets really noisy (unusable) above that on my 450D and I usually need to crop the image since I have limited reach.

Under good conditions....I am usually at 200 ISO.

Thanks for the replies. I am going to get the TC and try it.. It's definitely worth a shot and something I had not considered. I just "assumed" I would need the 2.8 to keep my shutter speed up. I shall see.

Have you considered the 100-400 f/4.5-5.6L? It has IS, and the f stops will be almost the same as the 70-200 f/2.8 with a 1.4x TC (e.g., f/4). I've heard this lens needs a lot of light, though.

so thats why the lights dim when someone pulls it out...


Filters are like Condoms ... Protection at loss of some quality.

The 70-200mm f/2.8 with a 1.4x TC works out to be a 100-280mm f/4, the 100-400mm goes to f/5 at 130mm and f/5.6 at 250mm so actually works out to be a fair bit slower. The lens makes up for that by having IS, but unfortunately it's of no use in sports.
