Are there ANY differences between the MEF-3 and MEF-4 microfocus attachments EXCEPT the attachment bracket?

Yes


Edit: the early MEF-3 were 10:1 reduction, the current MEF-3 & 4 are both 7:1 reduction, The MEF-4 is designed for the 4" focusers. MEF-3 for the rest.

True Matt, but the ONLY difference I can find (apart from the name) is the MEF-4 uses an attachment plate that is angled to fit the larger 4" pinion cover block, whereas the MEF-3 uses a straight attachment plate for the small 2.7" cover block.
