Adding a lens to my camera

If someone is selling this "old" lens, you should ask him (her) what kind of mount it has. These lenses are made for different brands. Most of the time you also can buy an adapter to fit it on your camera. No problem most adapters don't give trough the AF info, because this lens is an manual focus lens. More interesting is to know if your camera can work with manual lenses. Because most of the time you also have to set everything by hand. Like aperture shutter time and so on. So check the manual if it can, to avoid disappointment after you bought this thing. Also read what others think about this lens.

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.

Cordially

Promaster makes many different lenses. Some of their older lenses do not have the electronics to communicate with newer digital cameras, and you have to shoot in Manual mode. Could you tell us which lens you're asking about?

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.

Fitting is not always the solution. It is the software which recognises the hardware attachements. Either upgrade your camera software or use only the manufacturer recommended add ons. [email protected]

Yes the mz-7 Definitly uses a K mount.

Yes. but only the conversion lens

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

That's completely normal for those cheap wide angle add on lenses. There good for a little fun but nothing serious. I bought the lens kit for the Kodak DC3400, probably the exact same lens. The telephoto in that kit was actually pretty reasonable though.
