I wish there was some news as to when the new one is coming out. I'm tempted to try to sell some music gear to pick this lens up, but I want to see what's up with the new one!!

A couple from the weekend.
1.4x tc.
This first one is pretty much a 100% crop.

This is unfair, Gabe. Your images with the TC look like mine with the bare lens.

Thank you guys.

Yes, they are with the Sigma 2x APO EX DG tc. I used to have the popular kenko Pro 300 DG, but I found a like-new sigma for a good price so I thought I'd give it a try. It is visibly sharper than my Kenko was. I thought I had very good IQ going with the Kenko but with the Sigma it's even better now. I'm really happy with it.
My 2x is also a Sigma (and I tried 3 different brands before it, including the new Canon 2x III).
But also keep in mind that I have a pretty good processing flow to add to the quality also.

Very nice Ian.
I wish I could photograph more owls. I only had a chance in the spring when a family of great horned owls grew up in a local park. Of course that's when my 120-300 was in the shop for OS replacement (for exactly 1 month), so not a single photo came from this lens.
Fortunately, I also own the 70-200 2.8 OS, so that lens with my 2x TC provided me with very nice photos, since we were able to get fairly close to the owls.

Here's an advice regarding heat and our lens.

I've noticed one thing about this lens and I have a theory.
In warmer, especially bright sunny days, the sharpness starts to deteriorate after a while when the lens barrel gets warmer. I had this phenomenon going with my old 150-500 OS too.
Since these lenses are black, they obviously soak up a lot of heat from the sun. I think this must cause some internal disturbance of the air in the barrel causing a slightly less sharp image. This makes sense I also own big telescopes and when I use my telescopes (very rarely these days), I always need to place it outside for a couple of hours to acclimate to the ambient temperature before I can get the sharpest images. This is not a problem with low magnifications, but at 250-400x it is a huge issue.

I see that my 2x setup is most affected by this, which makes sense; highest magnification.

So my advice, if you are shooting outside under a bright sun and warm temperatures with a tc, try to throw a lightweight, white cloth on the lens to keep it from warming up whenever possible. (there is logic behind Canon's big white lenses afterall)

My most recent pics were taken on a visit to the Hawk Conservancy Trust (www.hawk-conservancy.org (external link)) where I was able to get really close to the birds - so close I was able to use an 85mm lens as well.

The smooth bokeh the 120-300 produces is remarkable. It really can destroy a background.

Do you think something like this might help reflect the light/heat?

Gabe... I noticed this the other day trying to shoot the shuttle's final flight. Had the cam/lens setup in a hot, warm day and waited a good hour due to delay. Needless to say, the quality turned out worse than I anticipated.

Sure that could help. I've been eyeing those Lenscoats for some time, not particularly the white one but the camo ones. I'm just not sure how good quality they are for about $80-90, and also wondering if they would or could harm the finish of the lens under the lenscoat by continued slight rubbing resulting from handling. Maybe I'm just too paranoid... :confused:
