using manual lens on K2000

As I shoot 360 panorama photos I need to use a Zenitar M2-8/16 fisheye lens,
this was OK, but now my camera has started only working on M & AV settings
no mater were the dial is set to ? I have set up the Aperture Ring Permitted OK
After reading on some forums that I must use a green button, I have NO green button on the camera, is this me being silly or have I missed something, some would be great, Thanks.

You have an exposure lock button. That does the same function in manual mode

Is this one screw mount? If so then just use Av mode and the camera will meter correctly. If it is a K mount with automatic aperture (I . E. The camera stops down while shooting ) then Av mode will still work but wide open only

The aperture ring will only stop down in manual mode. The light meter will not work but it is easy to just check out the play back review to see if the image is what you are looking for. This works with the older k-mount lenses. I need to look at the screw mount lenese types to see how they work. They have the auto and manual settings so I need to see just how they need to be set-up for use on the K-m I have.

The light meter should work in stop down mode when you use depth of field pre keen

The a/m switch on the M42 lenses is for auto aperture on screw mount bodies. It only can be used as an open close manual switch on K mount bodies. Read the sticky in the beginners section

On the K2000/Km you need to press the exposure compensation button to meter in manual. It's the +/- button labeled "Av" by the dial.

Hi Guys, thank you for all your help, I have been playing with the AV/M mode and getting some good results, I was not sure that the camera was metering correctly, I am happy now that the camera is working correctly, the manual fisheye screw lens is a new piece of kit for me, I was shooting 92 shots for the 360 pano's with my auto K mount lens, but now using the manual fisheye I only need shoot 27, so you see its a big step for me. if you would like to see some results, please go take a look :

Thanks again.

I have to say thanks as well. I had been using manual buy using a hand held light meter or by using the sunny 16 rule (that is using the shutter speed that is closest the ISO being used at f16) to us as a base for an exposure at least on right sunny days. That advice about the AV button has made my life that much easier now for getting quicker results in manual mode.

I was playing around this a older 50mm f1.4 screw mount lense that my girl has and found out that using the manual stop down setting for the aperture was needed to get the camera to produce a properly exposed picture. Using AV button set the shutter speed up. Hpefully others reading this will be helped in getting better use out of their camera in manual mode as well!!

One other note. I have been using older m series lenses and was considering trading them in for a newer DAL series 55 to 300mm lense for the K-m I have but I am not doing this now.

Not sure what fisheye you are using, but I have an 8mm samyang fisheye, with 180 degree FOV corner to corner. I get pretty good results with one shot, looking straight up, when lying on my back. I just need to make sure my feet are outside the FOV

Hi Lowell Goudge

yes we have the same problem shooting 360 by 180 panoramas, we have to put our camera bags under the tripod so when we remove it in Photoshop the bag is lost also.

Regards
