There was some talk a while ago about Pentax making a "collapsing" PK mount. The idea being that extended it coped with normal PK lenses with dslr flange focal distances. But retracted it allowed...

Easy: spring is fall

Too late, arriving at the ballroom door when the dslr industry is getting the sheet music out for the last waltz.

Lots of people willing to work long hours diligently and lots of wealthy people also willing to work long hours and who will risk investing their money in up to date productive industry and not in ...

Missed my posts Bob? I am even upgraded to Olympus compatibility - v1.8! I have been using the adapters on Panasonic M4/3 for a good few weeks now and loving it. If anyone wishes to buy me an E-M1 ...

Nah, not the Metabones EF to M4/3 adapters ... they are working really well. I am talking about the EF to FE MkIV adapter on a Sony A7R body.  I was comparing adapter performances last night and ...

I just downloaded and updated my EF to M4/3 adapters to v1.8 firmware. Easily done, now I am Olympus body AF compatible, I guess if I actually had an Olympus body I might be dancing a jig  ... ;) B ...

I have not particularly noticed "angst" except for my own angst about my Sony A7R. Maybe I read the wrong threads. However it seems that the idea of a FF sensor does tend to carry all before it. ...

Keep the box and throw the lens away? But seriously - Mitakon suffers form being a Chinese manufacturer in a world where apparently only Japan or Germany can make great things optical or ...

I have bought cheap(er) adapters for Sony E and FE mount and have found them often as capable as the Metabones more expensive versions.  But at the moment and based on the repaorts I have read the ...

I have not tried a firmware upgrade as of yet - I was looking for the upgrade for my EF-FE MkIV adpater on the Metabones site when I accidentally noticed the almost simultaneous announcement of ...

Neil Holmes is the Kipon adapter expert. As far as I know 1) The first release Kipon frmware had problems but was usable.  A good bit short on the anticipation and promo video.  But Neil said he ...

So if I am to understand correctly - OpenGL 2.0 is either built into Windows or is in the Olympus operating system and therefore with Windows 10 and a Panasonic camera I have no need to enquire ...

I learn something new every day .... LOL? ok, ok ... I know that one - even "ok".

Our dollar has fallen from parity to just 70 cents to the US$ which has made buying lenses not so amusing as it had been.  It also made buying (expensive) Metabones adapters a real leap in the ...

thanks ... now I need to know what IIRC is? I used to be a computer nut and actually created a successful GL (general ledger) package that has been used for years. But time has passed me by and my ...

I was just teasing Colin.  I have a few MkI Canon lenses that are working fine on the Metabones adapters using my GX7 (and even GM1): the 85/1.2, 17-35/2.8, 70-200/2.8 spring to mind, possibly ...

Yep, and I think that I have most of them already .....

V1.8 also fixes the compatibility problem that I found with the Canon EF 100-400mm f4.5-5.6 lens.  This was my only real problem lens. Now all I have to do is update my firmware .... Anyone know ...
