p.1 #1 · p.1 #1 · Konica Hexanon AR 57mm F1.2 on EOS (300D)


Some days ago I finished conversion of a Konica Hexanon AR 57mm F1.2 and want to share some first impressions with you.

I used it on a 300D and I like it!
I think it's in the same league as my Rokkor-PG 58/1.2.
It's a pitty that I cannot mount the Hexanon on my full frame camera (an unshaved 5D).
Due to the protruding rear element it's basically an EF-S lens now
The good thing for users with EOS-crop-bodies who might want to convert this lens: there is no need for mirror shaving. Before I adjusted the focus it was even beyond infinity without any mirror issues.

Here is the lens-camera combo itself and some results.
Some pictures are taken at F1.2 and some stopped down until F2.
All out-of-the-camera jpeg, only resized and compressed afterwards.

Congrats m-a-x,
You've certainly joined a fairly rare group of people!

I have one of those lenses too but use it on a Konica film cam. I think Dim.ka here has converted one for use on a 5D, however a lot of mirror surgery is required. Something like 5mm if I recall correctly.
I'm just wondering does yours have that slight yellow tinge when looking through the viewfinder? Mine certainly does, but I've only shot B&W with it so far so it's not much of an issue.

Congrats once more and have fun with it!
R.

Hello Ronan
Thank you, I am very happy about the lens!
Yes, the viewfinder is yellow-ish. Also the lens looks a bit yellow but this could be the coating as well.
However, I don't see it on the shots, at least on the day-time pictures.
for instance the cheese picture was shot on a sunny day with Auto-WB.

Some more:

That would be why the pics are fine - Auto-WB compensates the yellow tint, much like if you shot under yellow-ish light and WB it.
Appearantly the yellow dicoloration can be caused by a rare earth element used in old glass, but can be cured by exposing to UV light from the sun or a special lamp (read this on the forum here...).

Cheers for the update m-a-x.
One of your fellow Germans has a great site dedicated to Konica. I'm sure you are aware of it, but for others who don't sprechen Deutsch the link is here.

Ronan,
yes I found that site numerous times when searching for information on conversion but the site does not deal with tearing them apart

Dim.ka_,
your pictures are very nice. In fact, I have to thank you because I decided to convert the Hexanon after I have seen other pictures you made with it
One question with respect to your 5D: how does it look like when you look through your shaved camera? Do you have a reduced frame coverage (less than the original 96%) in the viewfinder? If the answer is yes: does it depend on the lens or not? And is it distracting?
Thx, max

Thanks, m-a-x. Concerning viewfinder - i will try to take a picture how it looks, but firstly i use Nikon DK-17M eyepiece (magnification by 1.2) and if you use fast prime lens 50mm f1.2 or 85 f1.2 up to f4 there is no real difference is your mirror shaved or not - when you stop down the lens defussed black bar from the upper part of the viefinder starts showing about f4 f5.6 and onwards, so if you use a lot lenses with f4 f5.6 it could be the real problem.

Hallo szanszan, ich schreib Dir eine PM.

Since this is an English forum and the colleague here apparently prefers German, I will answer that by PM.

Because of this lens I cannot get the idea of shaving my 5D out of my head http://www.greensmilies.com/smile/smiley_emoticons_headbash.gif

No disrespect, but I sort of find the image quality for this series of images not that remarkable?
