300 2.8 vs. 400 2.8.

I know this has been discussed several times. I searched and still have not decided on what exactly I want to do. Here is the situation. I currently own a mint 300 2.8 IS and I am extremely happy with it, but sometimes I really wish I had something with a bit more reach. I have a few options.

1. Sell the 300 and pick up a 400 either II (non IS)- no cost or IS - few grand on top of selling.

2. Pick up the 400 II (non IS) and keep the 300 as well.

3. Forget about it and live with what I have.

I am more interested in the people who own or have owned both. Thanks guys.

Why not add a 1.4X TC?

You can easily make up the 1 stop loss in ISO with negligible gain in noise.

I have used the 1.4.. I dunno. Even that sometimes is a bit short for some of the stuff I shoot. Baseball outfields are hard to reach lol.

2x = too much loss of light and IQ?

Unless it was during the day, then yes too much loss.

EDIT: apart of me likes the idea that for high schools I have the 300- typically pretty good length, but If I go to anything like college or pro stuff, the 300 is a bit short.

Then use a 2x tc on it. I used it that way no problems.

yeah... shooting night games at 5.6 is not gunna work.

I'm thinking the 400 f/2.8 + 1.4X TC is probably your best compromise then.

Im thinking if I can swing the cash for the MkII non IS after the new version comes out that may be the best bet. what do you think jay? maybe even the IS version.

I have the 400 2.8 II. It's an outstanding lens, you won't be disappointed with it.

get the 800 and be done with it.

Heres where I stand:

the 300 can sell anywhere from 3600-3900. I can easily pick up a used 400 2.8 II for less and have cash left over.

I can sell the 300 and put about an extra 2k into a 400 IS.

or I can swing the money for the 400 mk II and keep the 300.

Then he can't take pictures because he'd have to use f/5.6
