Reviews

Disappointed2.0/5

Disappointed I am just getting used to this lens. So far I have found it very hard to get a good focus, even using a tripod and remote shutter release. We are under a permacloud this winter, so I may get better results when there is lots of sunlight. But, I should have spent more for a better lens.

Lens5.0/5

Lens I love my new lens. Wish it had autofocus but I knew it when I bought it. Am having fun getting used to it and playing around. Taking some phenomenal pictures with it

Sharp enough!4.0/5

Sharp enough! This lens for the price has proven to be a good value. The reach allows me to shoot images that I would not be able to capture. Some the images are soft but acceptable. I mount it on a flash bracket for two flashes and tie it down to minimize shake.
