I searched on the net for a lens hood that fits my old Canon FD 20mm f/2.8 S.S.C. wide Lens of which I bought used when I was a kid. Still love this lens on my EOS R7 with the Fotasy FD-RF adapter. I couldn't find a new lens hood for this lens, but even the used one in somewhat of a good shape was really expensive at like $50 + $29 for shipping from Japan. One that looked beat-up located in the U.S. was still expensive! I really didnt want that one for sure. Then, I came across this lens hood made by Fotasy, the same brand FD to RF mount adapter for my R7. This hood is very inexpensive compared to the used Canon hood. When I got it, it looks just the one from Canon, and it fit the FD lens perfectly even with the UV filter. I tested this lens with the Fotasy hood and the Fotasy FD-RF adapter on, and it came out pretty good. I compared th 20mm f/2.8 with 3 other RF lenses with the wide angle capability, and with either identical f/2.8 aperture, and one with the f/1.8. These RF lenses have the tulip type hood, meant for the wide-angle lenses to avoid vignetting, which is a common factor using a round lens hood. 1st photo of the RF 16mm f/2.8 STM lens was taken with the aforementioned FD 20mm f/2.8 with the aperture set on Auto in low-light (just the window screen covering the window with the sun going down on the other side of the house) with the Fotasy hood on. I don't notice any vignetting either. Not bad for a super old vintage lens (mid '70s mfg. & bought it used Like New in the mid '90s) with the round hood? 2nd photo is the Canon FD 20mm /f2.8 S.S.C lens under the same condition with the same Auto aperture taken with the RF 16mm f/2.8 STM. It looks wider with the 16mm, and sometimes this is very useful with the EOS R7s 1.6x crop APS-C sensor (photo is 1.6x bigger than a full frame sensor). 3rd photo of the FD 20mm f/2.8 was taken with the RF 24mm f/1.8 STM lens. Its more zoomed in with the 24mm, but a little brighter with the f/1.8 capability. 4th photo of the FD 20mm f/2.8 was taken with the RF 24-70mm f/2.8L USM lens which costs $400 ~ $500 more than the EOS R7. It has a fast silent motor, and a fast aperture capable from the 24mm wide-angle to a 70mm focal zoom. However, when I zoomed-in on the photo taken with the RF 16mm f/2.8, it looked very similar at the same close range. However, the RF 24mm f/1.8 STM lens came out much better with a little more light-intake performance at close range. 5th photo was taken with my trusty Nokia 8.3 5G (007 Camera) with an 64MP APS-C sensor camera where lots of times, shown me better results over a DSLR. The line-up of the lenses I used, showing the actual darkness of the room; and the 6th photo taken of the line-up using the Night Mode RF lenses tend to come out better in sharpness and color in low-light performance over the old FD lenses. The actual room is quite darker than the photo, but it came out pretty good I think. Fotasys round hood for my ancient wide-angle lens even worked flawlessly than I expected. I guess the hood is built to Canon specs with the shorter rim for the wide-angle. I started looking for a tulip hood for this 20mm FD lens, but couldnt find any. Now, I know why this hood is the one for the FD 20mm f/2.8. I have only 3 ancient Canon FD lenses. 50mm f/1.8 kit lens which came with my Canon T70 bought Like New in the early 90s. Other FD lenses I have are, Canon FD 20mm f/2.8 S.S.C. purchased along with a 100-300mm f/5.6 Telephoto lens I bought used from a local camera store in the mid 90s. All three of these lenses incorporate a lens hood by Fotasy, recently purchased and sold by Rainbow Imaging through ZeeBooth, and they all work great! Vintage lens can be frustrating at times on a modern camera, but they are fun to work with overall, and makes it a good practice lens. I didnt Leave My Heart in San Francisco, but I did leave my photo hobby over there; and now, just picking it back up almost two decades later.
