Here's another question. Has anyone had experience with the SERIES 1 Vivitar 8mm F3.5 Fisheye?
I am not a great wide angle enthusiast but, have several ideas for using an extreme w/a or fish eye lens but, the price of most fish eyes are beyond what I desire to spend for a lens of this type. However, I have found this SERIES 1 Vivitar 8mm F3.5 Fisheye for only $150 USD with free shipping on Amazon.com. This lens is available under multiple rebranded names...
My last acquaintance with a Vivitar Series One lens was with the 90mm f/2.5 Series One Macro in a Pentax K mount. I was exceptionally satisfied with this lens so I am not really worried about buying Vivitar although I realize that Vivitar doesn't manufacture any of its products.
I also realize that on my Canon cameras, there is no electrical connection to stop down from viewing to shooting aperture, meaning that I will need to work at my shooting aperture. I also realize that this is totally a manual focus lens. No sweat with a lens of this focal length!
Perhaps, if I was considering this as more than "an occasional use lens" the above facets would bother me. However for my usage, and the lens price; I can live with these restrictions. If I cannot, or in the unlikely event that I absolutely fall in love with using the fish eye, I can always sell it and get another more sophisticated lens without incurring any great financial loss...
I know that I am bucking the trend, buy I expect to sell both my 5D2 (which I purchased used as an experiment) and one of my 7D cameras and use the proceeds to buy a refurbished 7D2. I am very happy with my 1.6x crop frame Canon DSLR cameras and plan to continue shooting the crop format...
