Mamiya 645 extension tubes

[verney]

Are there more than one kind of extension tubes for Mamiya 645 system? Do I lose any automation in my Pro TL?

The pro-TL uses the same mount and metering/aperture connections as all of the previous M645 system cameras. The newer 645 AF and AF-D use the same mechanical mount but have electronics in the lenses for the autofocus. The new lenses will not work on the older cameras, but the old lenses do work on the AF cameras.

There are at least 3 types of extension tubes for the M645.

3 types? 3 lengths but I didn't know there are 3 types. The ones I have couple to the meter and work the aperture automatically. I think mine are called the auto extension tubes #1, #2, and #3.

That would be three, right

More correctly, that would be three sizes, all of the same type.

By type I meant if there are extension tubes with different levels of information transmitted from lenses to camera body.

Just bought a auto #2 extension tube. I hope that it will make my 145SF to focus close enough for filling the frame with a babys face. I was little irritated yesterday as it didn't. I hate lenses that don't focus close enough.

There are two types - the 645AF series and the older 645 manual focus series.

Limited ability for close focusing is one valid complaint about the 645. Creates a market for extension tubes, eh?

Can I combine the three extension tubes?

 

[Ian C]

Yes. You can use any combination of the 3 tubes to obtain various extensions and the particular magnification that each combination gives.

My macro extension tube is automatic too, for my Pro TL camera. For regular close-up work you can buy a secondhand Macro lens.

There is also a "Auto Macro Spacer" that is for the 80 macro but is nothing more than an extension tube and can be used with the MF 645 lenses.

Unless you're using a metered finder, there's exposure compensation to worry about, too. This should help:

Hello guys,

I have an Mamiya 645 pro, and I come across a Auto extension Ring No.3-S .
What exactly this ring does? Can I do macro photos with him?

Thank you.

This ring brings the lens further away from the film plane so that you now can focus to a much smaller distance than with just the lens. The automatic aperture mechanism and TTL metering with AE prism finder still works with the ring. Yes, you can do macro photos with it. I think that you can only use the Mamiya lenses in the range 80mm .. 150mm with the extension rings.

edit: Mike Butkus has the manual on his website.
