Flushed with excellent results from using the Canon EF400mm f5.6 with the E-M5 and rediscovering the delights (and accuracy) of MF after years of AF, I happened upon a Pentax SMC 500mm f4.5 in ace nick converted to Canon EF fitting. This is quite a beast as can be seen from these shots, and weighs in at 3.5kg:

However it came at a good price and has the advantage that it has a manual diaphragm so it should perform OK for fairly static subjects, it's also a good bit brighter than the Canon. Reviews say that it is a good performer but suffers quite a bit from CA. Being stuck indoors since receiving it last night all I have managed to take is some images through a rain-soaked window so I am looking forward to some better weather for a true assessment, but here is a couple, medium cropping:

Pretty acceptable for a 20 year old lens methinks.

Do you mean through a pane of glass (or two) or was the window open at the time? If the former - very reasonable indeed :)

Through wet (and probably dirty) double glazing.

Mein Gott - ein Grossen Bertha Kanon! :D

Strewth, what a lump, you must have to be careful not to put it through the window without opening it.

Isn't it fun playing with these vintage lovelies though and so cheap too.

Definitely "not bad" images

Shows what some old lenses are capable of. I suspect it's a lot more than 20 years old.

That is certainly a Cannon :D , you jogged my memory, in the cupboard I have a Meyer 300mm f2.8 yes 2.8 in a Pentacon fit, and I just found a Pentacon to 4/3rds converter on Fleabay, so now can't wait for it to arrive.This lens was made in 1952.

That's a great aquisition, David. Just think, 1000mm f4.5 equivalent! Look forward to seeing more shots. :)

Wow, what a lens to have laying around in a cupboard. I wonder what other gems members have squirrelled away! :D

Looking forward to seeing some pictures when the adapter arrives. :)

I also still have the Pentacon 6 and all the bits and bobs :)

Ah, so it's a medium format lens with a large image circle? in theory that is even better as on 4/3 you will only be using the center resolution of the lens even at the edges of the frame. I bet it's heavy! :D
