I have a pentax SRL camera with two lens. Can I use these lens on a Digital SLR camera.?
Posted by admin | Under Pentax SLR Digital Cameras Tuesday Mar 30, 2010I have a pentax 28 – 80 lens and a tokina 60 – 300. I don’t know if normal and digital lens are interchangeable. If they are usable, which would be the best camera to buy
depends on the mounting of the lenses.
Most manufacturers started to use bayonet mounts for new cameras from the early 80’s on. so there is a fighting chance your lenses may work.. as to what cameras they will work in it will be manufacturer specific…. so that means Pentax cameras (or the Samsung rebadged Pentax).
so thats the good news
now some possible bad news
the leNs may fit on the dSLR body, but it may well not work fully.. that means you may have to manually focus the lens.. not really a problem (assuming the dSLR has a suitable focussing screen in the viewfinder (or if you can add one.))
depending on the lens you may have to manually stop down the lens to take photos… stopping down the lens can cause before taking a light readiong can cause problems with some metering systems.
If I were you I’d consider ditching the 28-80 lens, perhaps keep the telephoto and buy a pentax body. if the 28-80 lens is an especially good lens then consider keepign it and buy a body alone
OR
accept that the lenses don’t owe you anything and start from scratch,, and buy a dSLR becuase its right for you. you don’t have a huge investment in lenses so you may be wiser to buy for the future, and not because of the past.
one thig to bear in mind is that digital cameras due to their design have a multiplier effect when comapring to 35mm file.. for most cameras using the APS-C format this is about 1.5 to 1.7 x’s the nominal size (ie the 60-300 becomes approxiamtely 80…450mm
the only real decision in my mind is you want to save some pennies right now and use your existing len(s) or whether you want to embrace the digital world wholly. Ive heard some suggestions that although you can use lenses from 35mm cameras, quite often the lens quality is compromised when used in a dSLR.
BTW I was very impressed with the Pentax/Samsung dSLR’s I looked at.. looked very good, waterproof, but I was swayed by the Olympus E series lack of weight compared to the bloated size and weight of the Nikon’s, Canon’s and (sadly) Pentax
You can use your lenses on any of the current Pentax DSLR cameras. There will be limitations, of course, but you can use them.

As long as they are the K mount, then yes you can.
You probably wont be able to use the Auto Focus on the lens, but thats not a problem.
I have an old x2 teleconverter which I use on my K110D and K200D, and although having to use it in manual mode, its no problem.
Hope this helps.

Yes you can. If they are the older M42 type mounts you’ll need an adapter. Plus you’ll need to set your camera up to use manual lenses with it.

It pretty much applies to the K200D and K20D also.

There are a few more clubs in that site that you might want look at. You might even find photos taken with the same lenses as yours.

Hi baroque,
The short answer is yes, you can use those lenses on any Pentax or Samsung DSLR.
The long answer:
First, the Pentax 28-80. Pentax made 6 (six) different 28-80mm lenses over the years. I don’t know which one you have, but fortunately, they are all fully compatible with all Pentax and Samsung DSLRs. The first one was an "A" lens, meaning it was manual focus, but otherwise fully compatible with DSLRs, so you just have to manually focus. The other five were all auto-focus, and so fully compatible with all Pentax and Samsung DSLRs.
Now, the Tokina 60-300mm. It’s manual focus, and I haven’t seen a picture, but from what I’ve read it sounds like it doesn’t have an A or AE setting on the aperture ring. Assuming it’s Pentax K mount (not screwmount), that would make it operationally equivalent to a Pentax "M" lens. You can use those on Pentax and Samsung DSLRs, but a few more steps are required. It’s fast and easy once you get used to it. See this for more information on that:

But wait, there’s more on that Tokina 60-300mm. You may need to saw off part of the mount. See this thread:

Another issue to be aware of — The digital sensors are smaller than 35mm film (43% of the area), so you’re only using the center 43% of the lenses. The good news is that most lenses are better in the center, so you’re using the "sweet spot" of the lenses. If you noticed soft corners on film, they might be improved in digital. The bad news is that your 28-80 is effectively a 42-120 (multiply by 1.5), and the 60-300 is effectively a 90-450. So you’ll probably want another medium-range zoom, like the 18-55mm (effectively 27-77) that is the standard kit lens for Pentax and Samsung DSLRs.
And one last point. As much as those two lenses may have cost originally, the plain fact is that they have very little market value today. It might make sense to just pick the DSLR you want, then sell your old lenses on ebay if they don’t fit on it.
Good luck and have fun!
