anyone use this lens? if so, how do you like it? i'm thinking of getting one since it's way less $$$ than the IS f2.8 version and i'm thinking, for the price, i can live without 2.8 and IS.

If you can live without the 2.8 and the IS then its still an excellent lens especially for the cost. Its the 2nd best lens I've owned for sharpness and speed only to be surpased by the 70-200 2.8/IS. Oh yeah and its still a white lens so that means it HAS to be good [img]/ubbthreads/images/graemlins/grin.gif[/img]

I have the 2.8 IS and I like it, you can probably live without 2.8 IS since I'm assuming you have lenses that would fill that hole. I know it doesn't answer your question since it is the more expensive lens but they are cousins in the same family so how different can they be. It focuses quickly on the EOS 1ds, I don’t know if the camera would make a difference on focus speed. Here is one of my most recent shots. 1/80 @ f2.8 153mm off camera flash, hand held. Now if I can only learn to see the light as masterfully as you do.

70-200mm f4 L is a great lens. All you need is bit more light if used with strobes. I have both of these babies and sometimes I don't even realize which one was I using after the shoot.
Go for it.

I got the 70-200 f4 for the same reasons you mention. It was a toss up
between this or the Sigma 2.8. I choose name brand, one-stop and $200 difference.
The one-stop loss didn't make that big of a difference for me. I was just looking for a good zoom beyond 70mm. My Tokina 28-70 2.8 is fine below that.
I think my short comings are entirely on me from here on out.
Sorry I don't have any decent examples to show but here is a good site for reviews

Hope this helps Jimmy.

One more thing Jimmy, if buying this new you more than likely wont get the collar mount.
Kind of pricey but well worth it due to the weight of this lens, balances everything well.

the collar mount is for working from a tripod, yes? cuz i rarely go on sticks... or does it connect back to the camera? i confess i've never owned a lens that might require a collar mount. i'm usually shooting in the 35mm to 135mm focal length ranges, and i've done so for just about the entire time i've been shooting SLRs, which is since i was about 12.

It is for mounting on a tripod or monopod, if you shoot in studio with strobes
you shouldn't need it. $100 savings [img]/ubbthreads/images/graemlins/smile.gif[/img]

70-200 f2.8L, (145mm f3.5, 1/500 sec., ISO 200)


One other consideration depending on the camera you are using, you will need a lens with a maximum aperture of f2.8 or faster in order for the high precision focus points to work. On the 10D, D60, D30 and the Digital Rebel models there are no high precision focus points, but the higher end Canons have high precision focus points which only operate in high precision mode with lenses which have a maximum aperture of f2.8 or faster. High precision focus means the auto focus locks within 1/3 of the depth of field, normal precision focus points lock the focus within the depth of field.

Another consideration is that some autofocus points (other than the center point) are less effective with apertures slower than 4.0. While the 70-200 f4.0L is within this range, if you add the 1.4 extender the maximum f stop jumps to f5.6 (you lose one stop with the extender). Personally I use the 70-200 2.8L (no IS) and have found this lens to be a terrific value. With the 1.4 extender, you wind up with 100-300 f4.0 as well as a 70-200 f2.8, one very useful lens.

IS is a big deal, but often not mentioned is that the amazing low noise characteristics of the newer Canon EOS digital SLR's means that you can buy back shutter speed by increasing the ISO in lower light situations rather than worrying about lenses with IS (which by the way, only helps with camera shake, not subject movement, something often overlooked). The 70-200 f4.0L zoom is a great lens, but for a few hundred bucks more you can get the 70-200 2.8L without IS, and depending on your shooting style this lens may ultimately be the better value. (It also ships with the tripod collar at no additional charge).

For more information on the Canon high precision auto focus system, there is a detailed discussion by Chuck Westfall (Canon USA) on this website: http://www.bobatkins.com/photography...q/eos3af.html. While it was written about the auto focus system in the EOS 3 film camera, the specifics are applicable to all higher end Canon cameras. Note the table relating to lenses, extenders, and high precision auto focus.

I am a bit of a grinch concerning Canon zooms, for a lot of reasons (mostly involving the speed and accuracy of the auto focus system) I think you are better with the Canon zooms rather than other brands.

You're kidding, right?

What are you going to do with a 1.6 format camera and a f4 lens?

You've seen the photos of mine, of Andy M's of Allen P's... there is no such thing as "nearly as good as".. when it comes to lens selection..

As a matter of fact,... you could try to pick up a non-IS version on ebay in excelent condition for about the same price as a new f4 version lens..which doesn't even come with a tripod mount, which you will need, believe me, in low light shooting with that lens design..

Better yet, look at the 135mm f2.0 L lens.. it's one of my favorite lenses in my bag.. I use it all the time,...and it smokes the 70-200 f2.8 lens at f2.8 any day.. and is really nice and distinct at f2.0, even on a 1.6 format camera..

with the extra bucks you save, pick up a 100mm f2.0 as well! [img]/ubbthreads/images/graemlins/smile.gif[/img]
