Yep - that's exactly right. Nobody has yet developed an adapter that can change the focal length of a lens!

For those of you considering the use of M\F lenses on your Pentax cameras, here's a chart showing rough equivalent focal length of MF Format lenses:
645 Lens 35mm Equivalent
45mm 28mm
55mm 34mm
60mm 37mm
55-110mm zoom 34-68mm
80mm (normal angle of view)* 50mm
80-160mm 50-100mm
100mm 62mm
120mm 75mm
150mm 93mm
200mm 124mm
210 mm 130 mm

(Sorry for the formatting - I couldn't figure out how to fix it.)

I found this info at" https://www.*******************/2016/02/06/understanding-medium-format-crop-factors/. The site also has similar tables for other MF lenses, RB67, Hassy, etc.

The reason I posted this is that it helped me realize that I already have a 28mm and a 135mm equivalent to add to my existing 50mm Pentax lens. By using a Photodiox adapter (~$40), I'm able to expand the use of my Pentax ME.

Downsides are that shutter speed is fixed at 1/100 and that the use of a hand held meter is required. Upsides are that I can shoot film that has ISO vales greater than 800. Since I have some rolls of Delta 3200 (which I rate at 1600), this is interesting. Looking forward to some street photography once the weather warms up.

Film developing 101

First of all, don't get overwhelmed by all the options there are for film developing. B&W is simpler than color and requires fewer chemicals, so I'd start there.

Pick one film and one developer. Ilford HP5+ is a popular choice, it's a good film and forgiving of some errors in exposing and developing. D-76 is a very common developer; many people will claim (and obtain) better results with other developers, but D-76 is relatively inexpensive and you can buy it in solid form which you mix as needed. This saves $$.

Stay with whatever combination you pick until you can reliably predict the results from your development. Once you reach that level, you can then branch out, trying other developers, other temperatures, etc. I'd stay with the same film because you want to see what effect your experiments have.

If you want to see just how many variations there are out there, look at The Massive Development Chart. Don't let it blow your mind! By the way, you'll find a useful temperature chart in there for whatever film/developer combination you choose.

If all this sounds like it could take a while - it does. I've been doing this for more than 40 years and I'm still not done. There's always something else to try - that's what makes it fun.

The adapter I use is from Photodiox. It has no electrical connections, so everything is manual. However, since the Pentax ME only has 1 manual speed (1/100) that makes the rig essentially aperture priority. I've been using my Sekonic Dual Spot F (Model 778) which is a bit of overkill - but again, it's the one I have. (One advantage is that I can shoot film at iso greater than 800 - a limitation on the ME.)

I set the iso on the Sekonic and fix the shutter speed at 1/125. On B&W film (see above) the difference in shutter speed doesn't seem to matter. I'm trying some Ektar 100 now and I'll let you know how that turns out.

The size/weight isn't too bad, with a 45, 55, or 80mm lens, it's pretty easy to carry around. I imagine it's similar to attaching a big lens to a micro 4/3 camera in terms of weight and size.

Again, this isn't the rig I'd recommend to anyone starting out but it allows me to have some fun with existing equipment, while using an old camera to good effect. So, if you have some decent MF lenses and want to expand your shooting repertoire, you might give this approach a whirl. All you will be out is the cost of the adapter (and maybe some film if you really muck it up.)

Ontarian50 raises several excellent points, and I agree with them. However, one point that was missed is that fact that I have these MF lenses - and I don't have the longer 35mm lenses. Most of my film work is medium format.(Mamiya 645 and 6X7). I see no reason to spend hundreds of dollars on 35 mm lenses that won't be used very often, so adapting the lenses I have makes sense.

I'm certainly not advocating the use of medium format lenses in place of 35mm lenses, I simply noted that the use of medium format lenses is possible and can provide acceptable results in many cases. The little Pentax ME is small enough that, even with a MF lens on it, it can be easily carried in a satchel of larger coat pocket. This makes taking it out for casual strolls more likely.

So, I have this Pentax ME. I also have a Mamiya 645 pro tl with a set of lenses. For a couple of bucks, I bought an adapter to mount the Mamiya lenses on the Pentax. Of course, everything is manual and the only shutter speed available is 100. I used my spotmeter, set at 1/125 to determine the lens aperture for a given exposure at 1/125 sec. With HP5+, this approach seemed to work pretty well. This gives me access to a 45, 55, 80, 150, and 210 mm lens on my Pentax ME.

A cheap way to extend my lens inventory. (Excuse the dust on some of the negatives, the static electricity is bad here, today.)

Hi - I'd decided to go a different route; these lenses look quite good, good luck in selling them.

OK - thanks for the reply. I just purchased a Pentax ME SE film camera and am looking for a longish zoom lens like this one for it. I"m waiting for the test roll of film to come back from the lab to make sure there are no light leaks or other problems. If it pans out (should know by the end of next week), I"ll contact you about buying the lens.

After a lol of looking, I finally found a very nice Pentax ME SE with a 5- mm f1.8 lens at my local camera store. I just loaded some film in it (HP5) for a test drive tomorrow, so I'll find out in a week or so if it performs as good as it looks. I'll post a few pics of the camera on Monday.

Hi, all:

I just pulled the trigger on a Pentax ME Super with 50 mm and a zoom lens (not sure what kind). I'm been (and remain) a Nikon user for most of my 50 years of photography, but I wanted ot try something a bit different, so here I am.

I'm a retired professional photographer, befgore that a chemist, and for many years, I ran a small commercial darkroom, so I guess film is still in my blood. Although, I have a digital (Nikon D7100), I really enjoy shooting my F5 and my N2020, along with my F3 and FG cameras. I also shoot a Mamiya 645 pro tl with a wide selection of lenses/

I mostly shoot B&W (Ilford) but have been playing around with some Ultrafine film in 645 and I have to say, I'm pretty impressed with the grain and acutance - especially for the $$$!

I'm looking forward to learning about the Pentax systems - never had one although I know folks who were happy with them.
