For those of you who shoot birds regularly, what's the minimum focal length you would recommend, and what would be ideal. I'm using a 20D with the 1.6 crop factor and I have a 2x extender.
Ron

Edit to add I'm mostly interested in larger birds - raptors and "fishers" like herons.

-> a 120mm would do it too (if you're discreet): :lol: :-) :G

Forget the crop factor and forget the 2xTC unless you plan to shoot with expensive super-teles and even then I wouldn't recommend using 2xTC all the time.

You need min of 400mm unless you in florida.

If you're into outdoor 'portrait' it's also a 300mm f/2.8 here in Maryland: :cool:

I poke around with a 120-300 F2.8 and 1.4x & 2x matched teleconverters.
Gives me an 300 F2.8, a 420 F4 and 600 F5.6.

The 120-300 f2.8 makes a great portrait lens once you get used to it, and I can't justify spending the cash on a dedicated 400mm/500mm/600mm f4 for personal hobby use.

Me too, the 120-300 f/2.8 EX with a 2x extender @ 1/750s: :cool:

That's not my only issue - I can't handhold any them !!! ;)
I need to workout at the gym first, and then I need to get a sturdy tripod... or may be some gymbal/ball head to track theses flying babies... It sounds more like work to me than a hobby! :?

... I believe some other folk will agree with you as well: http://photo.net/photo/nikon/300-2.8.html

-> The DOF on a 300mm f/2.8 is shallower than my 85mm f/1.2L still! :shock:

Thanx all for the responses. The reason I asked this question is that I'm planning on getting a long lens this spring. I'm looking at the Sigma 80-400, the "bigma", (50-500), and maybe the Canon 100-400L. The extra $400 may be a big problem with the Canon though. With the crop factor and the 2x converter, it looks like a lot of mm. :shock::G:?:blah:
I didn't mention the lenses I'm considering as they have all been discussed before, although I wouldn't mind comments now taking into consideration how I plan to use it.

Thanx,
Ron

PS: I wouldn't use the 2x all the time, but it could make some otherwise impossible shots possible.

Edit to add: great photos guys -I should have said so earlier, but thinking more about the topic. :roll:

PeterP Mar 2, 2006 11:59 PM

With a 20D and all of those lens choices you would be giving up autofocus with a 2x TC. The 20D firmware ends AF at F5.6.

The Bigma is a good lens, lot of people used it to get started in birding. :!:

Given the choice of Canon 100-400L IS and Sigma 80-400 OS I'd pick the Canon because the Sigma does not have the fast ultrasonic focus motor. IMHO Big mistake on Sigmas part on an otherwise very good lens.

NHL Mar 3, 2006 5:40 AM

I probably get a Bigma if I don't already have the 120-300 f/2.8 EX which get me to 600mm with a 2x TC and sitll maintains focus: http://www.stevesforums.com/forums/v...mp;forum_id=11

1. You always want more reach ;)
2. Your lens is never long enough... :-)
3. f/6.3 is only 1/3 stop off from f/5.6 - I bet you can't tell the difference (the camera can't) :G
4. The Bigma is light as compared to the alternative for this kind of reach :roll:
5. People 'want' IS/OS more than they really need <- It comes for free on my 100-400L but I seldom rely on it :idea:

How about a Sigmonster anyone up for it??? :ak47:
