Lens Hood For Pentax A28 f2.8?

Did the A28 f2.8 lens come with a lens hood?

If so, was it a simple round hood, rectangular, or a tulip shaped hood?

Not sure if it helps but the lens database shows a square / rectangular hood. Mine did not come with a hood and I've never actually seen one.

Thanks John!

I didn't think to look at the lens database, or even better then accessories database, until after starting this thread. I did pass by there, and there was a rectangular hood for the M28/M35, the PH-SB49 which looks like it should work. I have found a Chinese seller that offers a reproduction for about $10 with free shipping, so I might give it a go.

I spent the day at a car show yesterday, using my A28 on the K-1. It was a bright, sunny day, and although non of my shots have flare in them, there were some that I composed, and then didn't shoot because of the flare.

The hood I use for the A28/2.8 has the following info on it:

Back: ASAHI OPT. Co. JAPAN 49mm
Front: SMC PENTAX 1:2.8-3.5 28mm 1:2-2.8 35mm

The hood is rectangle and is plastic clip-on.

Phil.

Lens Hood For Pentax A28 f2.8?
My "Street Lady" (Pentax-A 28mm F2.8) formed an unholy alliance (as shown on the left) with a metal 28/24 Olympus hood, when I wasn't looking... and then subsequently led my “Friendly Lady” (Pentax-A 24mm F2.8) astray too.

I have this hood also. Interior is flocked to reduce reflections.

Looks like this:

lol. I spent yesterday at an antique tractor show. Slightly overcast here so it was a great day for photographing the steam engines and tractors. I used the DFA 15-30. One nice thing with that beast is that you don't have to worry about the hood, its sort of permanent.

I made 200 shutter actuations with the K-1, and immediately deleted 7 images. After I got home and browsed through the pictures with Adobe Bridge another 29 shots hit the cutting room floor.

I've been processing pictures since I got up this morning, and so far 94 have made the cut and are uploading to Flickr.

I have 56 more to go, and not all will make it.

I'm liking digital, as it is cheaper than film, the results are nearly instant, and processing them is much easier.

This is the hood I got from china. RISE(UK) Screw in Mount 49mm 49 mm Metal Wide Angle Lens Hood for Digital camera free shipping-in Camera Lens Hood from Consumer Electronics on Aliexpress.com | Alibaba Group
If you also get a 72mm lenscap the hood doesn't need to leave the lens. Beware of the cheap plastic butterfly hoods. I tried them and although the butterfly was fine the throat of the hood vignetted.

This one look like the one that fell off my camera and was lost. It had a twist on grab that wasn't very reliable. I was sorry to lose this metal hood as I bought it in 1978; the plastic replacement doesn't make my 'heart flutter' although id does the job.

I had one of those square plastic knockoffs on my 35/2.4 and it worked well, but one of the two retaining springs loosened up and it would not stay on well, so I switched to a metal screw on.

According to K-Mount Page the A24/2.8 was not sold with a hood. For web searches the optional fitting hood product name is PH-S52 (Plastic Hood - Square, 52mm filter threads). The catalog number was 22690..
My error. Not about the A28/2.8, the info is accurate info about the A24/2.8 though.

I would expect that many different hoods might work. I have three different 28mm lenses having 49mm filter threads and three different hoods (two matched to their intended lens) and all eight* possible combinations fit without vignette for 24x36mm FF. Whether all are effective against flare is difficult to say.


Steve

* One hood will not fit one of the lenses.

But the A28 has 49mm threads.
