Question about Pentax ZX-50 35mm SLR Camera

1 Answer

Lens will not zoom in or out

Hello, Org. problem: I have had my camera for 10 years now and all of a sudden my lenses don't work. I take them off the camera, point and shoot and the shutter works fine. When the lenses are on, I can't get the lens to zoom or to focus, you can here the motor or whatever working but nothing happens. It stopped suddenly. What I have done: I took the lens off and took a steak knife to the part that connects to the lens to contro auto focus to pick at what looked like gunk I also turned with my fingers the little piece on the camera body that connectsto that part of the lens. That worked fine (you could here the noise of the motor as I masnually turned it). It is the same noise I wolud here when trying to auto focus from day one. I placed each lens on and now they work. CONCERN: is it the camera body or the lenses that need fixed?? And what can I use to clean that area of the lens (I don't want to have to carry a steak knife with me.) (Now I can still work the camera on manual focus and that is fine, but to follow a soccer game poses a challenge of its own. Many people have told me to just get another, but I have won national awards with this one, it's not that easy.)

Re: Lens will not zoom in or out

Brush off any lose dirt from both the lens and bayonet mount and the autofocus drive shaft . If you are still not getting camera to auto focus your lenses have an expert look at the body : this is not an expensive problem to repair on these Pentaxes either a small mechanical problem or the connection to the pc board is bad. In either case only the front of the camera has to be dismantled ( +- 1 hour of labour to do the whole job ).

Need lens (up to 200)

Lens needs are determined by the type of photography one shoots. Example, for my needs I use three prime lens, 35 mm, 50 mm, and 100 mm. Sold all my zoom lens purchased primes.

The question is what are you attempting to capture? On a zoom lens look towards a constant aperture, not one when we zoom the aperture changes.

Adding a lens to my camera

To be sure you can use the lens, buy a Canon EOS lens. The plastic ones, can be cheap. I bought my last lens 28 - 80 mm, couple of months ago, for 5 dollar. and a working EOS 500 was connected for the same price. (lens and camera are still in good working order) Don't try other brands, because even when you find a convertor, it could be the lens will only work on manual focus.

You don't need an adapter ring, you simply need the correct lens. Like many aftermarket lenses, the Hanimex was made in a number of different versions to fit many different camera mounting systems.

Your camera accepts lenses with a Pentax K bayonet mounting, so the fix is to sell your lens (it's not worth very much though) and buy another which also shouldn't cost very much. You can even get them for free simply by asking on FreeCycle, it's where virtually all of my film camera equipment has come from.

It *might* be possible to get an adapter, but it depends entirely upon which mount the Hanimex currently has (you didn't say, and it's not always obvious just by looking at the lens), and very few can be adapted to a K mount. Those that do will lose automatic aperture coupling, making the lens and camera rather awkward to use, and the coupling will likely cost more than another similar lens in the same zoom range.

What size lens do i need for this camera?

You just need any Minolta AF mount lens. Sony Alpha lenses also physically fit as Sony inherited the Minolta lens mount when they bought the company, but as they are a later development not all will be electronically compatible.

The size of the lens depends upon the focal length of the lens and you choose that according to how wide a field of view you desire. Typical lenses are 28 and 35mm wide angles, 50mm "standard" (approximately the same perspective of how the human eyeball sees images), 70 to 90mm short telephoto lenses (a narrower perspective and very good for portraits) and higher numbers are narrower perspective telephoto lenses for viewing increasingly distant objects. In practice, the available lenses will be incorporated into zoom lenses which incorporate a seamless range of focal lengths within one single model. The word "zoom" reflects the fact that you can seamlessly change from say 28mm wide angle through to 80mm short telephoto and every single setting between them

Any zoom which starts at less than 50mm and finishes in the short telephoto range is called a standard zoom and is the lens that most autofocus cameras were supplied with. The next most common size will be something like a 70-200mm which is a telephoto zoom (or tele zoom) and takes you from a portrait lens to a genuine 5x magnification telephoto. You may also find so-called "super zooms" which do the whole job on one, for example 28-200mm. but the more jobs a single lens tries to do, the bigger and bulkier it becomes and the image quality deteriorates due to poorer contrast and greater image distortion at each end of the zoom range.

This is not an exhaustive answer, as there are entire books on the subject, but hopefully it's been of help to you.

What size lens fits a Minolta Maxxum 3xi??

It depends entirely upon what you're after and the type of photography you wish to undertake.

Any Minolta AF mount lens will fit. 28mm is a standard wide angle, 50mm is a standard lens with a field of view approximately the same as the human eye, 80mm is a slight telephoto and for distant subjects 200mm is a long telephoto. Some lenses combine a few into one, they're called zoom lenses and will typically be something like 35-70mm, or 70-200mm. The measurements relate to the focal length of the lens, but generally the larger the number the longer the lens sticks out at the front. Zoom lenses are bulkier and heavier than fixed focal length lenses, but they're also the most commonly used types these days.

Konica lenses do not fit Minolta cameras. I think you messed something up.

Minolta MC and MD lenses worked on the older manual focus Minolta bodies. They will also work on the Phoenix and Seagull clones of the old Minolta bodies.

The Konica lens should only ever be mounted on a Konica camera.

Your 7000i is now a Minolta paperweight. You need to send your 7000i for repair or replace it.

You could also look on Ebay for another Maxxum body to use your lenses designed for the Minolta A mount. As a rule, camera lenses are not interchangeable. You can use any Maxxum lens on any Maxxum body as a rule, but Minolta changed their flash shoe after the original 7000 series. Flashes that work with your 7000i will work with any subsequent Maxxum.

Sorry, the mounts of Minolta manual focus lenses are different than their auto focus series. Sigma, Tokina and Tamron all make compatible zoom lenses to fit the Maxxum series cameras
