Pentax-F 50mm F1.7 - Lens hood

Hello everyone,

long story short. I bought the Pentax-F 50mm F1.7 AF - should arrive in a couple of weeks - after the aperture mechanism on my DA 50/1.8 broke.
A lot of people strongly suggested getting hood for this lens. I own only one 49mm lens. The "MH-RBB 49" for my FA 100mm/f2.8 macro WR.

I'm wondering if it's not too long (if it even fits)? Or should I get a different one?
Not many (Pentax) options for 49mm lens hoods around here currently.

Thanks for any help and/or suggestions!

Any generic hood should do as long as it is the correct filter size and for the correct focal length (50mm).

What camera sensor size?
I use a few different one's on my F 50 f/1.7 including the one designed for a Takumar 135 f/3.5 or 200 f/5.6 on my K-3. I did a number of shots of the sky and white walls and I can't see any vignetting so on crop it seems to work just fine. On a larger sensor I suspect it would vignette so if you are shooting a K-1 I don't suggest it.

With mine I found a slip on Pentax cap for binoculars that fits like a glove. The lens is quite long with it attached but it is a solid metal screw in hood. I have also used some Nikon 52mm hoods using a 49 to 52 ring.

Oh yes I forgot to mention - I use the good old K-5.

I agree with Haris F1.

A small rubber hood, 49mm size are low cost and collapse into a low profile for storage.

My F 50mm F1.7 AF had a slight accident and the top rim had a small piece chip out.
The rubber hood I have, has an inner thread and this is helpful for using filters, and protecting the damaged rim.

My metal hood is the size of the lens! LOL! But I have smaller rubber hoods and other options. The weight is mostly unchanged since the metal hood is very light. I find the size doesn't bother me much.

For your K5, I think the hood for your 100mm would cause vignetting. I have a love/hate for rubber hoods. I like that they can be folded in and pack smaller, but eventually the rubber separates from the filter ring and then I'm frequently fixing it, trying to glue it, and then eventually throw it away.

The best and certainly one of the priciest is this square clip-on hood designed specifically by Pentax for your lens:

My second choice would be a round metal 49mm screw in hood:

LONG Hood on an A Series 50mm f/1.4 - PentaxForums.com

In this thread you can find a picture of my A 50 f/1.4 with this hood attached and vignetting testing I did.

The Takumar hood mentioned by UncleVanya is about 2 1/8" long and 2 1/2" wide at the end. For an APS-C camera, it works great. It's somewhat expensive to buy. Look for a generic hood with similar dimensions, often labeled telephoto. It is quite long. A shorter hood will be OK because the F50/1.7 already has a somewhat recessed front element. I like to find something that makes it easy to put a cap on.
The Takumar hood is labeled Takumar 1: 3.5 135mm 1:4 150mm 1:5.6 200mm and sometimes you can find an eBay listing with a completely garbled version of that which has been ignored by other bidders.

If you want to shoot in style, the RH-RC49 is the one made by Pentax. However, it's much too small for APS-C, so I'd go for a larger generic hood if you want to have more optimal coverage.

I have the F50 1.7 and it is fitted with a cheap Chinese metal screw on lens hood marked "for telephoto----", it is about 54mm bore, and 35mm long. No vignetting on apsc, maybe on FF.
