Lens Hoods

I am looking for a lens hood for my 'SMC Pentax-DA L 18-50mm F4-5.6 DC WR RE', I don't really like the PH-RBJ58 hood and am wondering, are the bayonet fittings on pentax lenses universal to the lens size (in this case 58mm) and could I use a generic hood of that size from the brand?

The filter/hood size 58 mm is the for the lens. That is the specification you would look for on any prospective filter or hood of any brand. I prefer the tulip type hood. If you look at the offerings using the shortcut below, you will notice some inexpensive options. The fitting is usually universal for a product like that, as long as the filter/hood size is correct.

Studying photos of the 18-50 and the DA L 55-300, which also has a 58mm filter size, it looks to me like the hood bayonet fittings are different between the two, so I would not count on the lens hoods being interchangeable.

You should be OK with a generic screw-on hood, though.

Why don't you like the hood? Isn't that the correct hood for the lens?

An alternate option would be to purchase a screw-in hood.

I sometimes use generic hoods. Although overall, I prefer Pentax hoods because I've found them to be better made and more durable than cheap Chinese knock-offs.

What do you not like about the PH-RBJ58?

Pentax pays people who know a thing or two about optimising a hood for a given lens. They generally get it right. I very much doubt you will find an alternative which works better across the required focal length range.

One of the most useful types of hoods I find are rubber ones. That way you can shoot though glass without reflections.I have found, over the years some Pentax hoods vignette (the 28-70mm FA comes to mind)

LIKE HE SAID

Although I sometimes like to use folding rubber hoods because they store easier than some bayonet hard hoods and can be pressed up to glass as mentioned above.

I Use cheap, screw in rubber hoods. They do the job and have the added bonus of being collapsible and interchangeable between lenses, and they fit in your pocket

In getting a replacement hood, I would be somewhat careful about random hoods. A hood has to also be optimized for focal length as well, as longer lenses need longer hoods. I once tried a generic rubber hood on a 50mm lens, and it was pretty useless. I tried "extending" the hood with my hand and I noticed the hood would have to be longer to block out enough stray light. Of course that is also the case with a crop camera, which would benefit from a longer hood as well.

It's not so much getting a replacement, when I got my k-s2, the kit lens came with no hood.

Well that would have been a useful bit of information for your original post

Nothing else you will find will be as compact or protect the lens as well as the dedicated hood. Is is similar in design to the hood for the DA 21 Limited, which is brilliant IMHO.

But there are innumerable 58mm wide angle hoods available - rubber, plastic and metal, either round and petal shaped. Some of them are very cheap (less than $10 USD). As long as the one you choose does not vignette at 18mm you should be fine.
