Andy:

Yes, the Eyelike M-series did have a calibration chart that was included with the back. However, it was extremely rare that it was ever needed.

Some questions:

What camera are you using?
Are you on good solid tripod/monopod?
Environment is rock-solid (no trains, etc)?
Subject matter is rock solid and not affected by even a slight gust of air from movement?

I've found that generally, the only cameras that work well with 16 shot exposures are electronic cameras (Hassy H1, Mamiya 645AFD, with mirror locked up, or view cameras with electronic shutters.

You can contact me offline if you like.

Andy:

I haven't shot with a Mamiya Pro, but your overall setup sounds viable. Since you bought the back used, it's possible it's out of calibration. But you said 4 shot is right on the money, so I don't know. 16 shot can be a very trying experience in that regard. When you say 16 shot is not right, what do you mean? Are you seeing cross hair patterns along edges, or ??

I am a dealer for Eyelike (as well as other backs - Leaf/Hasselblad/Sinar) and have primary experience with the M-series (firewire-based). Because you indicated 4 shot was sharp, it doesn't sound like an out of calibration issue. However, Sinar now handles the Eyelike - product in the US at least - you could contact them for re-calibration.

Another potential solution. I could contact one of my Eyelike users and see if they would allow you to borrow their calibration chart and go through the process just to eliminate that possibility. Contact me offline if you like. Again, because 4 shot is dead on, I don't suspect a calibration issue.

Andy:

Ok, blurred is entirely possible. That is, if you mean "softer" than the 1 or 4 shot. If you add appropriate sharpening, does it still look blurred?

Andy:

You might want to try and contact me offline so we don't take up too much read-width, posting question/answer posts. The next step would be discussing "how soft"?

Thanks,
