Re: M50ii + EF-S 55-250mm STM + Kenko SHQ 1.5x Teleconverter

Well after some procrasination I finally followed some advice given on previous posts about modifying my lens to work with the Kenko adapter

Great! I hope you get as much a joy out of your extended 55-250 as I do out of mine.

The thing I did different is a did not chop up the mount, instead I bought a EF mount replacement part from fleabay that screwed on perfectly. It it well built and has given me no issues.

That's very interesting. Over in the Adapted Lens forum, Tom Caldwell did a similar replacement to mount the EF-S 55-250 IS STM on a focal reducer for M43. The EF-S extension back towards the sensor interferes with the optics in the focal reducer, just as it does in most extenders. However, he had problems with it being a very tight fit. Can you share the listing on Ebay? Perhaps there are some which are less tight? Or perhaps it's just a different fit between the extender and focal reducer?

Regards,

Alan
