What lens hood for EF 50mm mk I

As I recall, the 50mm f/1.8 mk I lens has a 58mm filter thread and the original lens hood was the ES65. Fortunately, the TS-E 90mm lens uses the ES65 also (latest version is ES65III), so even though your lens is long discontinued, you can still get a proper lens hood for it. BTW, you can use any version available, as they are only cosmetic changes.

Canon recommends ES 65, in any of its versions. A lot of people (myself included) use the ET 65 (also in any of its versions II, III). The ET is much more widely available (also used) and is deeper, providing better shading. The ET 65 also fits a number of other lenses, including 100/2, 85/1.8, 70-210/3.5-4.5 and others; if you have any of these, you can use one hood for several lenses. On the other hand, the ES 65, apart from the 50/1.8, also fits the 35/2.

It's interesting to note the significance of the Canon lens hood designations have no relationship to the lens' filter thread size.

 

First of all they are designated EW, ES or ET, which means wide angle, standard or telephoto. The number that follows each of these designations is the diameter of the bayonet opening on the hood where it attaches to the lens and on the mating bayonet leaves on the lens.

 

Furthermore, sometimes the letter designation does not match the type of lens, as in the case of zooms. Also, to be noted, Canon changed the bayonet fittings to achieve more robust and secure attachment on some recent lenses and just because an older hood has the same number, it may not fit properly on one of these newer lenses

There is no "mk I". The lens called the EF 50mm f/1.8 has a

deeply recessed front element. The built-in resistance to flare

would be undone by adding a front mounted filter, in which case

a hood would prove most helpful.

Nope, I used the ET-65 for many years on my EF 50 1.8 and it never--not once at any aperture--suffered from vignetting. Yes, I shoot many slides so no cropping by labs. The only tiny drawnback of the ET-65 is it is too long to reverse mount for compact storage.

Sometimes the light’s all shining on me. Other times I can barely see.

I have the es-65 and et-65 for my 50mm "Mk I" lens. They don't vignette on our EOS5 or Elan7EQD. The es-65 doesn't reverse mount when trying to store it more compactly, so I keep the ET-65 hood on at all times since it helps with flare when I use a filter on the lens. Also, I think the hood does a great job of protecting the filter threads as evidenced by lots of scuffs of paint on the hood that came off the walls of our house. By the way, I always have a 52-58 step up ring and use 58mm filters and lens cap on this lens. The hood clears without problems. I have a ES65 hood with one edge trimmed away to clear the body of our Elan7E when reverse mounted, but I use it rarely. If you are interested in it, e-mail me offline. I can take pics and send to you.
