I have come up empty handed when searching for the original hoods for some of my K and M series lenses. Are there any currently available hoods that anyone has used and can recommend for the following lenses?: K30mm, K55mm 1.8, M28mm 3.5 and M50 1.7. I currently have a Pentax hood for the M28 but I'm not a fan of it since it is the "turn the ring to tighten the rubber grips" type. Thanks for the help.

In the K and M series the clip on plastic hoods typically fit several lenses. The appropriate lenses were printed on the side of the hood.

They actually come up fairly often here and on eBay. For instance, a member here (gofour3) just had 4 NOS hoods in the Marketplace to fit the K55/1.8 - that hood also fits all the K series 50's. The hood for the K28/2 and K28/3.5 also fits the K30 as we as all the K35's. Search the listings for 'Hood' or some such broad word in Titles Only.

The hood for the M50/1.4 also fits the M50/1.7 and M50/2. There are three - 2 screw-on and a clip on.

The product code is descriptive. The M28's take the PH-S49. PH = Plastic Hood; S = Square; 49 = 49mm (size of the filter ring). Interestingly, that appears to be also the specified hood for the M50/1.7.

In some cases (usually the 50's) there is a round hood as well as a square hood.

If you look at the lens descriptions on Boz Dmitrov's K-mount Page the product number for the fitting clip-on plastic hood - you'll find the overlaps that way. Scroll down to 'Lens Data and Descriptions' and click on the red links.

You might take into account that the narrower Angle of View on an APSc sensor makes the legacy FF hoods shorter than they could be for best efficiency. Some users here, for instance, use a Takumar 135 screw-in hood or an inexpensive Chinese hood from eBay with 50mm lenses on Pentax dSLR's. For 35mm fllm, of course, you want the original.

You can make a 'Wanted' post in the Marketplace using the product numbers and descriptions. I think it likely you will have offers for all the hoods you need. You might also cross-post this message in the Film SLR Disucssion Forum and/or Lens Discussion Forum.

I picked up a used generic Vivitar 49mm screw in hood at a local camera shop for $5.00 for my M50/2. I haven't used it yet but it looks like it will work.

I use/prefer the super takumar metal hoods.
-- The 35 mm rectangular hood [originally for 35mm f/3.5 and f/2] works well on 24 f/3.5 (super takumar) and 35 mm f/2 (K) lens, and likely will fit the 30mm (K). You need step down ring to 49mm.
--I find the 150 f/?-200mm f/5.6 circular hood (49mm dia.) works well on the M50 f/1.7, and thus should also work on the 55mm f/1.8. Actually I checked and I see the 55mm is 52mm filter size, so adding a 52-49mm step down ring may vignette.

If you are using your lens on a APS-C sensor, you can use hoods designed for somewhat longer focal lengths and not get any vignetting due to the narrower field of view on APS-C. The advantage being better shielding of the front element from stray light, particularly direct light if shooting anywhere towards the sun. Comparing field of view angles in the lens review area would provide some idea of which hoods designed for longer focal lengths would likely work with your lenses.

Thanks for the info, all.

The nicest hoods, but not cheap are B+W from Germany. They are robust enough to take a hit without bending and denting

They can be bought at B&H photo or https://www.schneideroptics.com/Ecommerce/CatalogSubCategoryDisplay.aspx?CID=1200

To determine the length you need to use a program such as hoodcalc to determine the length without vignetting
