Canon EF300mm F/4 Is

Fri Dec 30, 2005 3:29 am

Well, easy question.. anyone got this lens?

How is it - let's say compared to the 100-400 or 70-200mm?

Hi Thomas....

The optics is better than a zoom lens. I couldn't compare images from them but some members during the last years have written about the superior image quality of the 300mm.
Of course you have other problems related to the fixed lens against the zoom ones.. The 100-400 is much more versatile and the 70-200 (2.8 or 4?) gets a bit short in terms of distance....

Worth every penny

I guess in terms of usage hardly compareable to the 70-200 or 100-400.

It's a prime, so your photos have to be planned a lot better. No way to zoom in or out, only that one focal length. If you want to find out if you can handle that, why not try to shoot one day only at one focal length, for example at 300mm and not zooming with your lens?
You have to be at the right distance of a subject for getting the shot you want. Not that easy.

All in all, optics are better, but it's a lot less flexible.

I had the opportunity to use a 300 f/4 at an airshow in 2004 and I was quite impressed. I shot with this lens over a couple of days, and as Florian said above a disadvantage is the fixed length. The advantage is that it produced some impressive tac sharp images. But again I was limited to 300mm, which did require a bit of planning and timing. In the end, I decided to go with a zoom lens as it is more flexible, but if the zoom isn't a problem for you, I'd highly recommend the 300 f/4.

I use this lens and think it's a cracker. Pin sharp and with any of the TC's is still an excellent lens. Although with the x2 TC it is MF with most bodies, except with the 1Ds I think. Someone will clarify that, but you will have AF on the 1.4 TC and still tack sharp.
I also have the 70-200 f2.8 L'IS and love that one too. I recently did some photography in a game park in South Africa and found the 300 + 1.4 TC set up just what I needed. But if you want versitility then the 100-400 is the answer. Never used it but a lot of photographers here find it a great lens to use.

Take care

I used to own a 100-400 but decided to go for a prime lens as the long end I found to soft and I hated the push pull zoom. Don't get me wrong, this is a very good lens and as described above it's versatile with one lens covering a wide focal range. Great at 100-300, soft at the longer range so you need to stop down with the aperture.

I replaced mine with a 300 f/4 L IS and a 70-200 f2.8 L IS. The 300 is now my main lens, it is light, fast and sharp. I also use it a lot with the 1.4x extender with great results too. Not so sharp with a 2x though. Fergul was right in that you need the EOS 1 range to get AF with a 2x extender on an f/4.

The 70-200 is a great lens but with a 2x extender doesn't compare to the 100-400. Close but not good enough to go for that option, I'd recommend the 1.4x for aviation work.

If you want one lens go for the 100-400, but if your budget allows I have been delighted with the 300, 70-200 and 1.4x extender. Maybe also consider the 70-200 f/4 L. Had one of those too, great little lens.
