If all the lenses are genuine pentax K mounts you will have no trouble using it on a MZ-7 ( oops ZX ) no adaptor needed. As for the ZX-7 focusing in low light all AF cameras have that trouble unless aided by a af spot beam, and even then 9 m is about the max effective range. I almost always use the AF assist on my flash when it starts to get a bit dark, even if the camera can still focus the spot beam helps it do so faster. Remember that the ZX-7 will not AF with non AF lenses but it will give you the infocus light to help you out. --- "GT CRISTOBAL, Rey Bernard C." <[EMAIL PROTECTED]> wrote: > I already own a MX and a set of 3 prime > (k-mount)50,135,200mm lens. > > I'm trading my C**** with a ZX-7. > what problems should I expect when I use the 3 prime > lens that I use with > the MX with the ZX-7? > Would it fit without problems? would I need to use > adapters?
