Question about Ricoh XR-7M II 35mm SLR Camera

What other cameras accept Ricoh lenses? We have a great 600mm f8 lens for our 35mm SLR and would like to find a digital camera that will accept this and other Ricoh lenses. Thanks in advance for any help you can supply. Ken

Ricoh used the Pentax K-mount.

Pentax are one of only two manufacturers whose current SLR's will accept the older lenses but there will be significant compromises:-

Not all K mounts will work; there's no definitive list so it's "**** it and see".

Most KA mounts should work (KA are the autofocus versions).

All lenses designed for 35mm film SLR's will behave as if they have an approximately 1.5x teleconverter fitted: a 50mm standard lens becomes a 75mm portrait lens, a 28mm wide angle becomes a 42mm and almost indistinguishable from the 50mm standard lens. A typical 80-200mm zoom becomes a 120-300mm zoom and your 600mm becomes a rather less useful 900mm although the effective aperture remains the same.

There will be little if any communication between the lens and the body: K mounts use a mechanical coupling to transmit aperture settings to the body, and the body stops the lens down during exposure with another mechanical coupling. This will no longer work. Some KA lenses will exchange information and automatically stop down. If your current 600mm is a catadioptric (mirror) lens then this is not an issue as it will only have a fixed f8 aperture.

Your current lenses will be to a far inferior optical specification compared to modern lenses. Genuine Ricoh/Rikenon lenses were generally no match for regular Pentax models of the time, and they in turn are generally nowhere near as good as modern lenses. This is because the old models not only use inferior materials technology, but also because modern optics are computer designed and modelled and are optimised for the particular requirements of a digital imager. However, you will generally find that the actual build quality of your old lenses will be superior to modern offerings and they'll be more robust. Also, unless you regularly make large prints or selective enlargements AND regularly use a tripod you may not see the difference in optical quality in real life amateur use. You definitely won't see the difference if you only ever display the photos on a monitor.

Personally, I cannot recommend Pentax dSLR's over any other brand on the basis of legacy use alone, and if the 600mm is the one good lens then I'd seriously consider selling it as there is a demand for good 35mm lenses. I'd give the same advice whichever brand of 35mm you previously used, unless you had a lot of high-end Canon AF/Nikon lenses and were going to buy an expensive full-frame digital SLR. Look at all of the competing offerings and choose what currently suits your photographic needs.

Hope this has helped to clarify things for you, all I ask in return is that you take a brief moment to rate my answer.

I have a canon Zoom FD 70-210mm 1:4 lens off a SLR camera. Will it work with digital cameras?


No Canon FD lenses cannot be used on Canon EOS system cameras (all autofocus Canons except for the ancient and obsolete Canon T-series 35mm SLR's from the 1980's use the EOS mount).

There are very few cameras which can take them (35mm or digital) without some kind of expensive mounting converter which would include corrective optics.

If in good condition though it's a great lens and can be used on plenty of old Canon classic 35mm SLR models such as the AE1, AT-1 , AV-1 and Canon T-series, all of which are cheap//free and readily available.

Are there any Vivitar digital cameras that will accept a vivitar 70-210 lens from a 35mm camera?


No. Vivitar currently does not make any digital cameras with interchangeable lenses. They do make a film camera with interchangeable lenses:

Depending on the mount on the lens, it may fit a number of digital cameras from another manufacturer. For example, if the lens has a Nikon mount then it will fit onto every Nikon digital SLR model, though perhaps not all features will work with every model.

What is the size of the lens for this camera?


The Maxxum 400si is an interchangeable lens camera, so there is no single lens for it.

If you're asking about the mount, it uses the Minolta A-mount so all such lenses, including current Sony-mount lenses, will fit on it.

If you're asking about the lens focal length, Minolta has made lenses ranging from 16mm to 600mm. These lenses vary widely in size (and weight and cost). The filter size also varies from lens to lens.

Or were you asking about something else?

Is the Vivitar Series 1 compatible with the D200 Nikon Digital SLR camera?


Yes. Bear in mind that due to the sensor of the D200 being smaller than a frame of 35mm film, the crop factor will make this lens seem like a 150-600mm.

I'm looking to buy a Nikon F65 35mm film AF SLR Camera and I was unsure if you can use the lens from a Digital SLR?


Yes, as long as it's not a DX lens. DX lenses are designed for the smaller image area of some digital cameras and will cause vignetting (dark corners) on a 35mm camera. The vibration reduction feature of VR lenses won't work, but won't cause any problems.

DX lenses will fit and work, but as mentioned above, you will get dark corners.

Pentax ES2; do bayonet lens fit digital Pentax SLR?


Any Pentax K-mount lens will fit any Pentax DSLR. The DSLR will fire the shutter.  There is a menu setting (RTFM) which allows the use of older lenses, but you will lose some of the automation (again RTFM). Remember to allow that the effective focal length when using a "film" lens on a DSLR body goes up by 50%.
A standard 50mm lens becomes a 75mm equivalent, but stays a large aperture.

I have a minolta 7000i non-digital camera with several nice lenses. Are any of these lenses compatible with any new digital cameras?


I am pretty sure that your lenses are just fine for your Digital camera(Minolta or Sony only) as they have the same lens mount. I you choose a KM5 or KM7 digital cameras your lenses will be longer by a factor of 1.4x, same goes for Sony cameras except A850 and A900. They will give you the same magnification ratio as your 7000. Minolta was sold to Sony several years ago, and they have been building a great reputation since. Your AF maxxum lenses will work great on any KM or Sony camera(ADI is available on distance integrated Minolta maxxum lenses only. You can tell by looking at a lens marking which will say "D" if it is compatible with distance integration). I find distance integration an extra not a necessity. If you have some great glass that you love and hold dear, then it would be a great idea to buy Sony. Note that another answer by miket756 is mostly wrong. Yes your lenses will get longer on APS sized sensors, but a 28 mm will never become a 150mm equivalent(thats just stupid). It will look more like 40-50mm on APS-C camera. If you got 2000-2700$ for Alpha850 or Alpha900 than your lenses will retain their mag factors. Good luck.
