Ok, here are the first set of shots. Now, don't forget, it was windy, I had the grip ballhead and QR plate mounted so I could see shake through the lens, and I was in a huge hurry because the sun was going down. I already took all that stuff off for the moon shots later tonight, so now it's mounted directly to my tripod. I did use mirror lockup for all of these shots, and ISO 800. The test tree was roughly 150-200 yards away.
Here is the scene at 50mm with the Tamron (red circle is the area I aimed for with the Opteka):
The rest are captioned, but I should mention the exact USM settings I used. The 2nd to last shot is the only one that is completely unprocessed from the RAW.
Here is the Opteka at 650mm. It was a little soft looking out of the camera, so I cranked up the USM in Noise Ninja before resizing, to 200% at a radius of 1.9.
Here it is at 1300mm. Same USM, but I increased the radius to 2.4:
And here is the 100% crop from the 650mm shot, completely untouched out of the camera. Ok, it's not so great, but remember, under $300.
And with some USM. I couldn't do too much USM here because of the ISO 800 noise:
My first impressions are, for web sized shots it's very usable. I'm not sure where they got the weight from, but this lens feels much lighter than my Sigma 500/4.5.
It comes with a cheapo carrying case that doesn't really fit once you attach the t-adapter, cheapo snap on lens cover that's more like a telescope cover, and no EF rear cap. It only has a threaded rear cap that you can't use with the t-adapter attached.
I took some shots of the setup with my P&S which I'll post in a little while, but now I am chomping at the bit waiting for the moon to rise. I'm going to let it get a little high in the sky before I do those shots so I'm not shooting through too much atmosphere.
What do you think? Should I order like 50 for us and see if I can get them for like $100-150 a piece? I'm thinking this would make a great starter wildlife lens.
