I am using my Tamron AF70-300mm F/4-5.6 Di LD to try and capture Birds in flight at great distances and I cant get focus on the Birds I am using AI Servo .

On the Lens there is a scale on the focus ring with what looks like a "L" and then the Infinity symbol but it stops at the "L" ????

if that's a crop you're asking too much of the lens...you'll need to get closer...a lot closer

Figured so , I just thought that at Infinity with that distance the Bird will be in Focus .

Also is that "L" Mark Infinity ?

How much did you crop it? I agree that you may be asking too much from this lens if that's a 100% crop.

yeah bird-in-flight shots are very demanding of gear.

I try shooting these damn vultures that fly around the new buildings under construction across the street. Every day around 3:30 - 6:00 they swoop around looking for scraps of food left by workers. Sometimes they fly so close to my balcony (less than 20ft away from it in fact) and I run out with my 40D+70-200mm f/4L IS. And the closest shot I've got thus far is about 50ft away. And its not good enough.

You're asking a LOT of your lens. Its not you, its the lens.

300mm is nowhere near enough for birds in flight at any sort of distance. You need to be much closer.

And getting birds in focus while in the air is a royal PITA that takes a lot of practice even with a larger lens.

I'm sure there are much much much vastly more skilled bird photographers than I out there, but I usually end up with a very small % of keepers when I try to take pictures of birds in flight. It takes a lot of practice and even then its tough.

I don't think you can ever have enough zoom for birds. I use my Sigma at 500mm and I'm constantly wishing for more zoom (and thats on an APS-C).

Birds are especially difficult because they have so much texture from their feathers. Anything short of incredibly sharp tends to look out of focus if you are pixel peeping.

Get closer to your birds.
Practice a lot (Sit at a park and take a few hundred pictures of pigeons flying around)
Don't pixel peep.

Your "L" is merely a shorthand symbol directing you to note that one infinity symbol is serving for both meters and feet. Once you are at 300mm, all camera shake is multiplied. The lens is not image stabilized. Therefore you have a shaky image. The way to avoid that with that particular lens is to be sure you are shooting at 1/500s minimum, which means you would need to up your ISO, perhaps.

You also must get much closer. Be sneaky or use a car as a blind--birds tend to tolerate a vehicle getting much closer than a person on foot.


Canons to the left, Canons to the right,
We hold our L glass toward the light,
Digitizing in a snap reflective glory
That will forever tell our imaged story.

Thank you advaitin so if that's what the "L" mark is I should be able to get past it ?

No... the shorter leg of the L indicates where ∞ is. What advaitin meant was that the L is only there as to avoid having two infinities stacked on over the other, since ∞ feet = ∞ meters.

If you go beyond the short part of the L (the part in line withe the marker), you're focusing past infinity.

I saw this in the manual and meant to ask... what does this mean?

For instance, if I'm shooting the moon MF, why can't I just twist the focus ring until I can't "focus" any father?
