70-300 IS and 75-300 IS? Which one is better

Guys!!

I have not used these two lenses. So, I need your opinion in this regard, which one of them is better and how?

70-300 IS

70-300, no contest, stay away from the 75-300 series...!

I've been lucky with both versions of the lens.

From a 75-300mm f/4-5.6 III:

70-300 is much better.

I had a 75-300 IS once, complete garbage.

Just to confirm: 70-300 IS

No one with a 400 2.8 should own a 75-300!

agreed.
70-300IS

...besides, canon doesn't make a 75-300IS

I had the 70-300 IS....a great lens, sharp and a pretty fast focus. I gave it up because it was a little slow on the bird shots. Suckers jump too fast! I loved this lens, sorry I let it go!.

I've heard a lot of people refer to the 70-300 f/4-5.6 IS as a "Hidden L" when it comes to IQ (obviously not in build). I would say that the IQ is awesome.

I took this a few hours ago with my 70-300 and a Kenko 1.4 TC. I got the lens off Craigs list in the Spring for a real bargain.

70-300IS with a Kenko 1.4 TC? I asked on here several months ago about this combo and was told "Not possible with this lens." Have you any daylight shots with this setup. Nice pic BTW

Can't comment on the 70-300, but I have the 75-300 III and managed to take some half-decent snaps at Wimbledon with it this year:

When I was considering buying a TC I was going to buy the Canon since I have the 70-200mm f/2.8L IS but reconsidered when I was told in the thread for this lens that the Keno will work so I picked one up and sure enough it works and seems to work well.

I thought that I wouldn't have Auto Focus but I do all the way to about 280mm. It is really strange that it stops after that point but this is at low light (shooting the moon).

Unfortunately I am a night crawler (work graveyard shift) so I don't see a whole lot of daylight especially this time of year. I will try and shoot some shots with when I get up later today.

vote for 70-300 IS
