If you’ve just bought a DSLR and can’t afford more lenses, I have a great solution for you. Hit eBay and look for a 24mm film-era lens from Canon, Sigma, Tamron or Nikon. You might also find Vivitar for Canon or Nikon mount. Make sure they are f/2.8, as most should be. Search for “24mm Canon FD” or “24mm Nikon AI.”
The reason I suggest 24mm is that it’s decently wide for video and f/2.8 is really the minimum aperture for less-grainy video. Of course, on a crop-sensor camera you’re at 38.4mm which is still decently wide.
Now you need an adapter. The EOS adapters have a glass element that lets you focus to infinity. The Nikon adapters do not. So some would argue that if you have a Canon it is preferred to get the Nikon to EOS adapter, as you aren’t adding an extra glass element to your camera that can degrade quality.
Here is the Photodiox adapter that I use, and Here is one for Nikon to EOS. Do some research though, you don’t want to go too cheap on these adapters. Expect to pay $60 to $70 for a good one, but a $25 one can be had.
Pictured here is my Sigma 24mm f/2.8. I really love it. It takes excellent photos and it’s wonderful for shooting video. Plus the macro lets you get very close to your subject.
Now, using these old lenses you will be focusing manually. And you will be dialing in the aperture manually. But hey, these lenses cost from $60 to $120 on eBay. And because they are prime lenses, they have a very low aperture that’s perfect for shooting video. And real pros manually focus video anyway.
Also, compared to new cheepie lenses, these old film lenses are build like tanks. Just MAKE SURE the seller says there is no fungus or fog in the lens. It’s even better when the seller takes a picture looking through the lens. Fungus CAN infect other lenses or your camera I’m told. So, yuckie to that!
Enjoy your repurposed glass! Upload some pics on this thread or in the forums!
