Canon Lens FD 135mm f/2.5 S.C

Price paid 2018 --> 40 euros

This is a review of Canon Lens FD 135mm f/2.5 S.C tested on Sony A7


The lens (credit mir.com)

 


Construction is impressive weight is 630g.

There is a nice built-in hood and the filter diameter is 58mm


Let's see on the field how it performs.
Shots are not stellars one they are just to give you how good or bad the lens his. 


f=2.5 only 100% center, there is no point to show corners.

SAMPLE 4

SAMPLE 5

Conclusion f=2.5

The bokeh is awesome, I like the vigneting, but it can easyly be atenuate in post pruduction.

You need chirurgical focusing, you have no room for error, this is nearly impossible to focus if subject move.

It is prone to CA in some case.



 Which aperture is needed to have good sharpness across the frame ?


 Let see on this picture and extreme left corner at f=4 - 5.6 - 8 & 11

 



100% LEFT CORNER

  

100% CENTER at f=4 just to show how good it is, same at f=8..

 


 I think 5.6 is far accepteble for corners, and who look at extreme corners anyway ?
But wider aperture is prone to CA, so I prefer to stick to f8 most of the time.


CONCLUSION

Well I am not neutral, old canon FD lens are my favorite one, there are the most I use and I want to use.
This lens is cheap and very good, if you like the retro feel of Canon get one now !

KONICA Heaxnon AR 35-70mm 3.5-4.5

Price paid 2017 --> 15 Euros

The lens (last photo from allphotolenses.com)



Expect the color rendering, there is nothing fantastic about this lens.
Not for landscape work at all, it could be use for B&W street photography where edge doesn't really matter.
I found the lens soft @ 35 and 50mm. corner are not good as well, a little better @ 70mm.
Prime are far more better, the Olympus 35-70mm 3.6 is far more better, but remember, this lens is real cheap and is usable if you don't mind the corner.
The macro mode is OK.

Construction is not great, all plastic...

Tested on Sony A7, real life photos, jpg straight from camera.
