Using the 7DII, all conditions being equal which lens has the better qualities for BIF.

or: is the 100-400L IS Version II a better one to compare to the 70-300L IS ?

The 70-300L, which I owned since it was introduced, has very good IQ and guick focusing IMHO. The 100-400 v1, which I also once owned, has an early version of IS and reasonable IQ. The biggest difference is that the 70-300L has better and updated IS. However, there is no substitution for reach.

The 70-300L is a little lite regarding FL and it doesn't take Canon TC's that well. This lens does work fine with non-reporting tc's like those from Kenko.

I would lean slightly towards a later date code version of the 100-400 v1 because of reach and surprisingly, the push/pull design.

The 100-400 II is much better than those other two.

The 100-400 is better than the 70-300 with a TC. IMO

You feel the 100-400II is better all around than the70-300L IS without a TC?

I agree with Imagemaster. The 100-400 II is that good. When I bought my 100-400 II, I sold my 70-300L and 100-400 v1.

I'd go for either 100-400 over the 70-300L for BIF; or hell, one of the 150-600's if you need real reach on a budget.

The 70-300L's main endearing quality is the absolute quality of the lens IQ, AF, IS, and build in a compact package.

I guess I would keep the 70-300L IS for outdoor rodeos, horse jumping, etc. and buy the 100-400II for BIF.
The weight of the 70-300L is substantially lighter.

Judging from the copies I have the 70-300L IS has better IQ than the 100-400 Version 1 There is no difference in IQ between the 70-300L IS and 100-400 version II, if that is your question.
If we are talking about about reach and versatility that is another matter. Than the 100-400s is your choice.

That was my question.

I had a 70-300L and now have a 100-400L II and there is no doubt that the 100-400 II is superior at every shared focal length, and adds the ability to go from 300-400. However, this comes at a significant cost/weight/size tradeoff.

If I was going on a wildlife trip with a 500mm prime and wanted a second lens to pair it with, I would seriously consider the 70-300 as I love how maneuverable and effortless it is, and it really is good glass with excellent sharpness from 70-250 and good sharpness from 250-300.

To make a long story short... both are good lenses, but the 100-400 II is worth the money and weight if you plan to always shoot at 300mm and the ability to zoom further to 400 would help even more.

I didn't see this post. I would agree between 100mm and about 250mm, from 250mm onwards the 70-300 is at its weakest and the 100-400 does definitely better it. I found that a great deal of my photos from my 70-300 were at 300 and I find that the 100-400 takes better photos at 300 or 400 than my 70-300. Hope this helps!

The bottom line is that the 100-400 II equals the 70-300 plus you get the additional reach.
I guess I will have to replace my 100-400 I for the newer version. I think I will still keep my 70-300L

Thanks

I have both the 100 400 II and the 70 300L and have also held on to the 70 300L for sports shooting due to the weight when the 400mm is not needed. When shooting 2 or 3 consecutive FB games (daytime) that savings in weight is appreciated. For the same reason it's a first grab for casual outtings with the gkids when I'm going to have to pack it all day.

IMO the V1 of the 100 400 doesn't measure up to either of these lenses.

Your opinion appears to be the general consensus.
I will sell the V1 and get the V2.

Thanks,

I agree, the old original 100-400 is a killer lens for field sports (maybe for BIF)
