Question about Kenko Teleplus MC-4 DG for Konica-Minolta Maxxum 2x (MC4AFDGM) Lens Converter

1 Answer

Camera will not recognize the lens

I purchased a Kenko telephoto lens that was advertised to fit a Sony a-350 camera; however, when I attempt to take a picture the camera has a "no lens detected, shutter locked" message. I notice the lens sensors in the camera body. Can I make this lens work on my camera?

Hi, I have a Minolta 7D. I bought an M42 screw lens adapter, an almost flat plate, however the camera kept saying "no lens detected". Then somewher on the web I found a solution: On the menue screen I found "Shutter Lock" with the choice On or Off. By switching to off I can now use 42mm lenses. Though there is no AF and the metering works with setting the aperture manually. Good luck and maybe you find the Sony to be the same.

NO F stop showing on my screen


No. The lens lacks the electronics to communicate with your camera. You have to switch the camera to Manual exposure mode. Set the shutter speed on the camera and turn the aperture ring on the lens to the desired aperture. You also won't get any metering help from the camera.

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.

Is the Sigma Telephoto 400mm f/5.6 APO AF lens compatible with the Sony alpha camera?


Sigma makes their lenses with a variety of mounts. A lens with a Canon mount, for example, will not fit onto a Sony camera. Assuming you get the Sigma lens with a Sony mount then yes, it will be compatible with the Sony alpha.

I just purchased a Sigma 2.8 f=28mm for canon but I don't know if it will fit my Canon EOS 500 N (same as Rebel G) 35mm SLR film camera. Can you help with this question.


Canon EOS 500N has an EF lens mount, so all lenses with Canon EF mount will fit. All lenses with MF and EF-S won't fit. If you purchased Sigma 28-70mm f/2.8 EX, then it have EF mount and will fit EOS 500N.

I have a vivitar telephoto lens for the camera, but not sure how to mount the lens. If I take the outer ring off, I dont know if the lens that came with the camera is suppose to also unscrew, or if there...


None of these Canon Powershot cameras have a lens which will remove.
The ring is only for a special kind of add on lens for either wide angle or telephoto, which will only fit this camera or possibly a few other models.

Never try to unscrew the lens, you will ruin the lens permanently.

Tiffen 2X teleconvertor telephoto lens


I was testing the new Kenko 2x teleconverter I just got. Seems to work, but only at full zoom. But I left the epson supplied adapter ring on when I turned the camera off, and it interferred with the lens cover, and jammed it. It's a 4 leaf shutter assembly, and mine is screwed up so it won't open or close. Needless to say I'm kind of unhappy. I've heard Epson service is good, guess I'm about to find out. If you use the adapter, take it off when you turn the camera on or off!
