I have recently stumbled upon three Olympus prime analog lenses:
50 mm 1.1:4 bayonet mount
50 MM 1.1:8 screw mount
135 MM bayonet mount

All in almost mint conditions and at a fair to what a consider inviting price.
Questions:
There is adapter/conversions rings for those lenses?

There is an OM to MFT adaptor from Olympus and 3rd party for around $20 on Amazon.

I have used the Amazon 3rd Party they work fine.

What happens to effective focal lengh ( Crop size ) ?

on EM-5 the effective length is a multiple of 2. so

100MM and 270MM

I'm assuming i will operate in manual mode loosing auto focus and other auto features.

They will work in Manual Mode just set the EM to A mode and in the IS mode set your original focal length 50 or 135.

You will stop down the lens with the manual rings on the lens.  the 50 1.4 is wonderful I have that one.

Am i talking nonsense ?
Thanks
