Deciding on a Fisheye Lens Purchase
Toward the end of last year I decided that I needed to purchase a fisheye lens. The question was, which one? No, I don’t mean that I had to decide whether to purchase a Nikon lens or something else. I started buying only Nikon glass a few years back and have not regretted it at all. The question that I faced was whether to buy the DX fisheye or not.
The DX lenses from Nikon are intended to be used with their digital cameras. In a nutshell it means that the lens is designed for the smaller focal area found in most current digital camera bodies. Until now I have always decided to get the full-featured “film” lens because they work just fine on my film cameras. The will also work on the digiital cameras but the focal length is effectively increased due to the smaller sensor. This is great for longer lenses (a 300mm becomes a 450mm on a digital camera with the smaller sensor) and stinks for wide angle lenses. 
So why would I even consider it for the fisheye? It’s because the fisheye lens geometry is so precise that it will only work properly on one type of camera or the other. Decisions, decisions… what to do?
I’ve Got Something to Say
This site was one of the very first sites that I ever set up. It started out hosted on the free member pages that America Online offered. Eventually I decided that I wanted to get a domain name and set up a site where I had more control over how things were done. I still have the original code that I used on AOL though.
