   10.5, Adapter
 
 

After a couple weeks shooting the Nikon 10.5 on the Fuji I'd say the combination works well, so well I might even take it on my next trip. But I'm not saying using any adapted lens is a cakewalk. It just so happens that this particular lens' strengths hide the adapter's weaknesses, which are the lack of auto focus and a poorly marked aperture control.

So why is this lens so well suited for this application? Even if you don't have the lens and the body you can go to dofmaster.com to run the numbers, and they show that this lens is going to be easy to use.

Let's try it out. Choose an APS-C body such as Fujifilm x100, x-pro1, select the 10.5mm focal length, a f/2.8 aperture, and then enter a subject distance of 2m. The results show something interesting: everything between 0.99m and infinity should be in focus.

Now change the subject distance to 2000m, which would be infinity on the lens. Dofmaster shows depth of field is 1.95m to infinity. In other words, if you just leave the lens on infinity and don't touch the aperture ring you'll get everything in focus from 6 feet to infinity. As a touristy landscape lens this pretty much covers most of my needs for a fisheye.

Mind you, If I didn't have the Nikon I'd buy the Fuji-mount Rokinon 8mm. Like the Nikon it's a fish eye and strictly manual focus, but unlike the adapter it offers a marked aperture ring. Even though you can shoot all day at 2.8 it seems a little odd to me not to step down a bit on a sunny day.

Not a shot I'd typically post but it shows that the adapted lens works quite well on the Fuji.

The fisheye is useful if you want to get a really expansive shot, like this one from a deck at Harbourside co-housing. I think this was a little underexposed, which is something I am seeing with this lens. Easily correctable of course, just dial in a little exposure comp.
