'Twas my birthday a few weeks ago, and yesterday I saw my brother for the 1st time in nearly a month. His birthday was last week, so we exchanged presents. His gift to me was the "infamous" Phoenix/Opteka/Samyang 650-1300mm zoom lens, complete with 2x TC for total range of 2600mm. He knew it wouldn't be what one would refer to as a "quality lens", but he was dazzled by the zoom range. The lens "features" a push-pull type zoom, fixed aperture/focal length (F8 @ 650mm, F16 @ 1300mm), and manual focus.

Sunday was too overcast to do more than horse around with it a bit, however today is sunny and I endeavored to make some more earnest shots.

Interstingly, the minimum focus distance is closer @ 1300mm than @ 650mm. The resolving power is brutal - 1000 lpi? - contrast is severely lacking, and PF makes my Tammy 70-300mm look tame.

So, here's a shot of a robin about 25-30ft away, ISO 1600, 1/1000s, 1300mm, lots of post-processing:

For comparison's sake, here's a quick snap with the Tammy at 300mm. The robin had just fled (figures), but I circled his location in red.

Good times. :lol:

Blow that section of the Tamron image up to the size if the 1,300 and see if you gain anything by using the long zoom or if cropping would get you the same image.

Great idea, Tom. I was certain that the blown-up Tamron shot would be worse, and indeed it is.

I cropped the empty branch shot so it refelcted the same scene as the Phoenix shot (sans bird, of course), and then blew up to 800 pixels wide - same as the 1st shot.

Here's a "glory shot" of the Phoenix lens attached to the K100D. It would make quite the effective cudgel, methinks.

Not bad, really. Sounds like way too much work to me, and I'm another one who doesn't even own a tripod. Somehow I don't think that lens would fit into my lifestyle at all. Impressive looking, though. How heavy is it?

Harriet,

In the trunk of my car right now are two tripods and a monopod, They hardly every get taken out. But I still wouldnt have enough to support that lens.
