Takes Me Back
For the price, this is a great lens. It takes me back to my manual days. It give extremely precise crisp focusing and the bokah is unique. It's light weight and compact and a great addition to any lens collection.

Not s Good
Images simply were not sharp enough and the depth of field is too narrow for anything but long distance landscapes or objects of greater than 100 yrds. The adapter ring-lens mount can loosen while carrying or using after several focus attempts.

Great lens for the money.
I bought the lens in sep 2010 via internet from Adorama in Nyc. The lens was most propably wrongly assembled as you can't get a even close to sharp photo. When adjusting distance you see only a non focus preview and the final pic is useless. As I tested the lens and found it does not meet any of my need. I got angry and put it away. Today nearly 3 yers later I found it in my closet, got angry and checked the lens again. Total useless. Asd I am so far away from Nyc I didn't even think about a return. Don't buy if you can't test before purchase.
Not bad, for the money. Sure, a huge Canon zoom is much better. However, if you just want to have fun and get some crazy nature shots, this is the impulse purchase for you.
could not use it
I am pleased to use the Pro Optic as a long distance lens for wildlife shots. The pictures retain all the color and details I require.
Has worked well in the short time I have used it, so far no problems.
If your T-mount "breaks in two pieces" check the screws that hold the two parts together: they do come loose. If you loose one (or more...) of these you'll just have to get a new T-mount... Keep a jeweler's screwdriver of the appropriate size in your camera bag so you can tighten these screws as needed.
Excellent choice for long lens, somewhat soft but works well with A setting on Nikon. Some sharping needed but great quality for super long lens, suggest tripod or monopod. Suggest adjustable T mount adapter.
Back in the olden days when we we used analog capture, we used a trick for determining exposure on the fly called the sunny 16 rule. On a sunny day at F16 you would use the ASA/ISO index as the shutter speed. So if using 200 ASA/ISO then you would be shooting at 1/200 of a second. Open up 2 stops for the shadows. Of course you would need to shift your shutter speed accordingly if you wanted to use a different f stop. Hope this helps.
Tested this one against the Phoenix brand I had and this one was sharper, but not as sharp as a more expensive model. Works great with APO DSLR to get an effective range of 800MM to shoot the moon.
