Don't know about a proper Intervolometer, but I did purchase this cable release which lets me do bulb exposures. I even took pains to install black flock paper - the same stuff Canon uses inside the TS-E lens - on my Metabones adapter. I've tested/experienced it myself with my TS-E 24mm II. I'm not sure, but I think this mainly affects TS-E lens users. Apparently stray light can bounce around inside the adapter and reduce contrast. I did slip a simple rubber o-ring to reduce any potential concerns, but frankly I haven't seen it.Īnother potential unwanted light issue concerns the Metabones adapter itself. I have an a7 and a7R and don't have any light leak issues. Having the L-bracket attached to the Metabones adapter puts everything in better balance.Ģ. I'm not at all enthused with the notion of using a camera-mounted L-bracket on my a7 and a7R cameras because then the camera's lens mount has to bear the full burden of the cantilevered adapter and lens. This means the Metabones adapter is bearing the full load of the lens and camera when mounted to a tripod. I hightly recommend the Hejnar Photo L-bracket and spacer.

I primarily use my Zeiss MF lenses with the Metabones adapter and I feel it's a fantastic fit. I do feel the metabones III adapter is recommended - Novoflex is working on one too, but till then I don't like the alternatives. The dynamic range and resolution is just killer.ġ. Rick, my feeling is that for photographers like you the a7R represents more positives than negatives.
