Introduction top Intro Specs Performance Recommendations This lens looks like my dog dug it up in the backyard, but before I threw it away, I tried it, and the Canon FD 35-70mm f/4 FD is an unusually good performer. The 35-70mm f/4 is unusually sharp right out to the corners, even wide-open, and has little or no distortion throughout most of the zoom range. The Canon FD 35-70/4 is also built tough; it's almost all-metal. It's a two-ring zoom. There are no weird macro settings; it focuses directly down to 1.6 feet (0.5 meters) at all focal lengths as part of the regular focus range. The 35-70/4 has one weirdness: for some unknown reason, the filter threads and front element move around inside the front outer lens barrel. To put on a cap or filter, you have to zoom to 35mm and focus to 0.5m to get the front part of the lens to come forward enough to reach the threads! When new, it shipped with a rubbery plastic Canon cap that fit fairly snugly over the outer lens barrel.

Distortion The Canon FD 35 70 4 has strong barrel distortion at 35mm, and has no visible distortion at 50mm and 70mm. For critical use, use these values in Photoshop's Lens Distortion FIlter:

Ergonomics It works great; jut turn the rings. I've already explained the weirdness with with the hooded filter ring above.
Filters, Use with As covered above, you have to dick with it to attach filters. The thread is not on the front of the lens; it's back inside the lens where it says "Canon Zoom Lens..." The inner part with the filter thread moves in and out as you zoom, and rotates as you focus. Good luck trying to use a polarizer!! Forget step-up rings; they won't fit inside the barrel.
Lateral Color Fringes As seen on 3,600 DPI scans of Fuji Velvia 50, there is some very, very faint lateral color in the corners wide open, which goes away a stop or two down.
Sharpness Here's the crazy part: the Canon 35-70mm f/4 FD is sharp at every setting! It's sharp even to the corners wide open. Few lenses are this good, so this simple but tough lens stands out.
Recommendations top Intro Specs Performance Recommendations Considering that these sell used for about $35, if you want one, go for it. I've always considered 35-70mm zooms as a product for the feeble minded; personally I prefer a smaller, faster, cheaper 50mm f/1.8 lens and I walk forward or back a few steps to zoom.

If you haven't helped yet, please do, and consider helping me with a gift of $5.00. The biggest help is to use these links to Adorama, Amazon, B&H and eBay when you get your goodies. It costs you nothing and is a huge help to me. eBay is always a gamble, but all the other places have the best prices and service, which is why I've used them since before this website existed. I recommend them all personally.
Thanks for reading!
