Pentax-M SMC 50mm 1.4 - Lens hood

Hi guys,

A newbie here and I just want to ask if what will be the effect if I use this lens hood (28mm / 35mm) for a Pentax-M SMC 50mm 1.4? It fits on a 49mm filter thread and I don't want to buy it unless there will be any bad effects.

(Photo below is not mine. Its also here in Pentax Forums)

Thank you in advance!

It will work but may not be as effective as a hood designed for the M 50. The hood serves a number of functions including lens protection, resistance to flare, and increasing contrast. This one is designed for wide angle lenses and is shorter than it would be if designed for the 50. The design is such that the hood will have some tolerance to avoid vignetting at the corners. I personally prefer the collapsing rubber hoods although they are also not optimized for the focal length in the way that modern tulip shaped hoods are designed.

As stated above, it won’t be optimal, but if you ever get a 35 or 28 you’re set, I believe that wil work well on the DA 35/2.4 also.

Something like this would offer better coverage for the 50mm lens........ JJC replacement Pentax PH-SA49 lens hood. Compatible: Electronics or the rubber hoods advised above work just as well.

It won't help much on a 50mm, more so if you use a crop frame camera. In that case, you apply the 1.5 crop factor and get one marked 75mm, or 85mm would be the closest you can get.

It is however a cool thing to have, especially if own one of the lenses marked on it. Or plan to own one. Get the hood, get the lens. That's how it works.
