The Pro and Super take different prisms to the older series :-(

<p>

Any of the older prisms will fit any of the older bodies, though (I've

got a PDS on my 645J) - so you'll need to track down a s/h prism.

<p>

If you don't need the automation, the PDS is the best bet. The older

AE doesn't have the spot/averaging syetem of the newer prisms - though

I guess you know this and it's why you're asking this question!

Just bought a couple of spares myself! I know of a dealer in Leeds (UK) with one in s/h at 20ukp - they're usually 30-40ukp s/h.

<p>

However, the inserts available new for 645 Pro backs are compatible with older bodies - although they may not be compatible with your budget :-(

Welcome to MF!

<p>

There isn't an integral meter, so there's no ASA dial on the body - it's on the prism finder (if you've got one and it's a metered prism).

<p>

There should be a filter thread on the 80mm lens. I don't know the size, but on my 70mm/2.8 it's 58mm.

<p>

Take some time to study the loading path for the roll film. There's a diagram on the insert as a guide (I missed that first time and got a blank film!)

<p>

Watch out for depth of field - 80mm on 645 has a field of view similar to around 55mm on 35mm but the same depth of field as 80mm on anything. This applies to all focal lengths and is a MF drawback with wideangles.

<p>

Also be aware that the shutter release lock just locks the button - a cable release will still fire the shutter (BTDTGTTS!).

I don't know what mail system you use, but I just filter on the 'from' e-mail address and anything from mfd@exeter.ac.uk goes to my MFD folder.

<p>

I'd noticed that the list isn't anywhere near as active as it used to be, and having just spent ages getting as far as being able to type in a reply (over 10 minutes on a 64kbit/s 'kilostream' link!) I can see why!

<p>

It's far too much hassle to post/reply to messages compared to a simple e-mail. I know that the old server had its problems, but I found it more user-friendly than the new web-based system.

A couple of local photo shops have 2X converters for the M645 s/h at reasonable prices (under 100ukp).

<p>

One is Vivitar - not sure about the other, but it isn't Mamiya.

<p>

I know that TC's are generally recommended for longer lenses, but I would like to get a focal length for portraits on a tight budget and was contemplating a 2X TC with my 70/2.8 to get a 140/5.6 for <100ukp rather than trying to find the 300+ukp for a s/h 150/3.5

<p>

Has anyone out there tried this sort of combination and can comment?

<p>
