I've already ask some opinions regard to the lens choice but I've still some dubts... excuse me!
I'm evaluating to buy a "entry-level" zoom lens (and not expensive.
Reading in the forums I understood that:
- a 70-300 (generally f4-5.6) give good performance but tripod is often necessary and because lightness it's more indicated for day outdoor shots;
- 70-200 f4 more expensive but excellent for portraits and fixed focus improve its capacity.

My dubts:
- the max f.l. 200mm it's really shorter than 300mm when subjects are far or difference is acceptable? what about conveter lens?
- which of them can be considerate a multi-purpose lens: portraits, macro, zoom quality,.. and whatever you think it can do!

Obviously all opinions and experience on this kind of lens are welcome.

Thanks a lot for help and patience

I am facing a similar dilemma as I have realised that "fat" glass is where I need to be - i.e. consistent aperture of f/2.8 or thereabouts. To this end I am looking to move away from my 18-200mm plus 50mm prime set-up to something along the lines of 12-24 (~f/4), 24-70 (f/2.8), 70-200 (f/2.8).

With this set-up I can extend the 70-200 using a 1.4x (98-280mm, aperture = ~f/4) or a 2x (150-400mm, aperture = ~f/5.6) tele-converter. Not optimal but I figure this is reasonable.

So I would always go for the fastest glass and then think tele-converter.

But there are other ways, too.

I would say get the 70-200 f/4L lens. It should be a great multi purpose lens, you may not be able to go birding with it, but you are also not going to do that with the 70-300 f/4-5.6. If you are using a crop body (seems you are), then the 70-200 lens is actually longer, multiply 70 and 200 with 1.6 (the crop factor). If you want an even greater focal length, then you just get an extender (1.4x (recommended) or 2.0x).

One thing about buying either of those lenses is that if you buy a L lens then you are getting the guaranty of a sturdy build and great optics. You should check out what kind of pictures people here have been taking with the 70-200 f/4

The price for the 70-200 f/4L and the 70-300 f/4-5.6 is simular (at around $550 at BHphoto) so you would just have to choose what you prefer.

I would definitely recommend the 70-200 over the 70-300, because of the build and also the red ring (L), you know you are buying quality and no BS.Both lenses are multipurpose but I think you would be much happier with the 70-200 rather than the other one.

Hope this helps.. ;)

I would go with the Canon EF 70-200mm f/4.0L USM if I was looking at only those two lenses (the ~$500 ones). Personally I would wait and buy a better longer lens and one with IS.
