Well as I have mention in my last thread the 70-300 IS goes and the 80-400 stays (70-300 at 200 with 1.4 TC beats 80-400 at 400 on sharpness and contrast. At 400 the Toki has similar resolution to that I saw on the Canon 90-300 USM (sort of painterly)). So I lose a stop, but gain 3 stops IS, better IQ and weight and USM!

What do you mean fully stowed? Is the focusing on the 300 NOT internal? I thought both lenses were like 8-10 inches in length (I guess that is not zoomed out and focused though or something?)

When I extend the hood it gains a few inches.. that's what I mean by racked all the way out.

I believe! I believe!!


Neil.... good call on that. If apertures are equal, IS wins hands down. In my personal opinion, it takes at least 1.5 stops of aperture to beat a 3 stops of IS. But if it's equal....there's no contest. And comparing the Toki to a 90-300.. ouch.... I can never live with that kind of IQ again.

Heh, even with the hood fully extended I would think it's about a foot, right?

9.5" without hood with caps on. Hood adds two inches (11.5").

100-400 add 4 inches (15.5" total). Now that is the Beast indeed.

out of your top three picks, my personal pick is hte 100-400 and the main reason is because of IS.

Is the 15.5 inches fully zoomed out?

Anyway I think it's obvious the 300mm F/4 is my lens for its size .

Yes, correct. Wanna buy a 300/4 IS? Mint condition, two owners, first one was a hobbyist who knows how to take care of good glass ("Cuz I'm replacing this one with a 500/4 IS"), second one just upgraded to 100-400 and never took the glass into difficult situations.

Ok, after following this thread for a few days, I have been convinced to trade in my 200-500 for the 100-400L. It's only money . . .

Thanks, Lightstream. I had been following that one, too.

That thread helped me make up my mind as well, but as this one specificly delt with the 100-400L and 200-500 lenses, so I decided to post here.

No worries..glad we could be of help

I made the journey myself and I am glad to have arrived.... I shot the Tamron, never liked the plastic or the DC focus drive. Bought the Bigma, too heavy. Bought the 300/4 IS - very nice but not a zoom. Geez....what a long journey it has been

Yep. IS, full time manual focus and construction are the difference makers for me. I'm willing to pay for them.

Focal length was the other deciding factor for me. I was not willing to trade focal length for IS because I try to use a tripod for telephoto shots. I think construction is about dead even because I do not like the push pull action of the 100-400 compared to the zoom ring of the 50-500.
