I don't have a good answer, though I don't think you will go wrong with either. Both sound great and I've had good results with the 300 f/2.8 + 1.4X for action (not so great with a 2X.) But I use the 300 f/2.8 for sports and often need the speed.Am looking to get either of these set ups in the future 300mm f2.8 + 1.4xlll extender or 500mm f4 for wildlife has anyone got any opinions on these to which might be the better option .

I have both and I would recommend the 500. There's little if any difference in the image quality of the bare lenses, but the 500 is better for two reasons and they are both related to the Extenders:Am looking to get either of these set ups in the future 300mm f2.8 + 1.4xlll extender or 500mm f4 for wildlife has anyone got any opinions on these to which might be the better option .

A word of caution: Canon has announced they are no longer repairing or supporting the 500mm f4. I don't know about the 300mm, but I think it may also be on their list. So this may factor into any decision you make. If you don't get a good one, you may have a hard time getting it fixed. Even third party repair shops may be unable to get parts.Sorry I should of said I am looking at mark 1 versions in both
Then used I guess? Then they're all in the same price range, from slightly below $3000 to around $3500 for the best condition ones. The 300 is arguably a bit cheaper.Sorry I should of said I am looking at mark 1 versions in both
Just seen your new post in which you clarify that you would be buying a Mark I. Obviously budget will play a part but personally I would be very wary of spending a four-figure sum on a lens which can't be repaired if something goes wrong.I have both and I would recommend the 500.

- AF performance is better with no Extender, and AF performance with the 1.4x is better than with the 2x. I get a much higher hit rate with the 500+1.4x than I used to get with the 300+2x, and the bare lens is better still. The biggest difference is with moving subjects, but even with static subjects I'm more likely to achieve perfect focus when working fast.
- If you want maximum reach in an extreme case and the atmospheric conditions allow it, you can get a maximum focal length of 1000 mm with the 500, but only 600 mm with the 300 (without stacking TCs).
The other point is that the 300+1.4x is only 420 mm so the 500 immediately gives you more reach.
The other side of the coin - when your subjects are big enough and/or close enough, it's an absolute joy to shoot at 300 mm f/2.8; and the 300 is a lot lighter to carry around! But as I said I have both and I use the 500 more than 90% of the time.
hmmm...then i have some news for ya:I'm assuming you mean the 500mm f4 II and my response is based on this assumption. If I were you I would buy the 500 because you get adequate reach with it for most wildlife and if you find you need more reach, you can always buy a 1.4X III later. If you start off with the 300 + 1.4x and it isn't long enough, you would be limited to getting a 2x. I don't think your image quality with the 300 + 2x III will be as good as a 500 + 1.4x III.

So where is your 500 + 1.4x comparison? One shot does not prove anything. I've been using Canon extenders for almost 25 years and have owned two generations each of the 1.4x and 2x. I have also been using Canon super telephoto lenses since the days of film with over 12,000 images in my files. So I hesitate to say that I do have a bit of personal experience. I never was as satisfied with the results with the 2x as I was with the 1.4x. You've proven that in at least one instance (and using the latest 300mm lens, not the first gen lens the OP is considering) you can get good results from a 300 + 2x. I am just expressing my opinion based on my experience that a 500 + 1.4x will give better results than a 300 + 2x under identical conditions.hmmm...then i have some news for ya:I'm assuming you mean the 500mm f4 II and my response is based on this assumption.

as it is, most of the comments on this forum is based on anecdotes and theories, not based on 1st hand personal experience, and in most cases, those anecdotes and theories pass as "facts", which will affect someone's decision making on purchasing that lens or camera!

I remember being in a similar contest when i got my super tele. In this case it is absolutely no contest to get the 500f/4. Not to make things more confusing for you but I'll go ahead anyways.Am looking to get either of these set ups in the future 300mm f2.8 + 1.4xlll extender or 500mm f4 for wildlife has anyone got any opinions on these to which might be the better option .

A lens without a teleconverter always performs better than one with a teleconverter.Am looking to get either of these set ups in the future 300mm f2.8 + 1.4xlll extender or 500mm f4 for wildlife has anyone got any opinions on these to which might be the better option . Thanks
