Agree, my apology if that sounded a boring question but I recently came across some lovely lens like Konica M-Hexanon to pair with my A7r/A7. Honestly, I didn't even know about this lens and what it produced in small package made me curious about other such great lenses which I am not aware of.



Yes, I love my FE55, just wondering about rendering you mentioned, can you please elaborate.



Lovely picture and I agree. In my limited testing, it held good againsr Konica M-Hexanon and FE55. If someone likes, will be happy to post comparison.

Here is an example FD55/1.2 compared with FE55:
Sony A7/(r) image sharing thread - Page 221

Notice how there is still physical vignetting at the edges of the FE55.
Not a certain bad thing, but I am surprised, given its price.

Another one with the physical vignette.

Bokeh also starts to swirl a bit.
Again I am surprised about it given its a modern design.
Its not a definite bad thing (I like swirly bokeh lenses, but not for this price).
But given the context, if I paid so much for a modern design lens, I'd want absolute reliability.
With reliability, I mean that its dependable in most situations and not have some quirk affect the photo when I need it.
The same can be said of most lenses (they will fail somewhere, but they don't cost as much)

Notice how the OOF lights becomes 'shifty'

Another one

We are talking bokeh here and its subjective.
As I said before, for the money, its a Zeiss (or is it a Zony), Zeiss like drawing, got AF, not too big and heavy, very sharp.
Not bad a deal if comparing to the likes of a Summiron M asph or Zeiss ZM 50/2

Best is meaningless in lenses it seems to me.


The very best lens will let you count the hairs on a hamsters backside, but when looking at the most significant and important images taken over the last 200 years, the lens quality and razor sharpness is never mentioned.


Looking at a Vietnamese lady weeping as her flesh falls from her body following a napalm drop, I don't recall image sharpness being mentioned once.


I could name 100 lenses that are pretty damned good, many of them Pentax and Takumars, and any of them will produce outstanding images in the hands of a good photographer.


The best lens? that is the one on your camera when the image you need to capture appears. The more important and significant the image, the less important the lens becomes.


Get a decent lens and stop trying to chase that tiny resolution improvement that an even better lens promises.


Take better images with your existing lenses.

Which are the best 50mm or 55mm in any mount? I am currently using SMC 50/1.4 & Canon FDn 50/1.4 with A7r but wondering about other manual focus options including Distagon etc

Thanks
I would go with the CZ 55mm F/1.8. Excellent lens for your A7r. Since you already have the K mount adapter I would look for the A 50mm F/1.2. The DA* 55mm show too much distortion on the A7 and it wasn't designed as a MF lens with aperture control.

Comparison on the 5D MKIII vs the Sony FE 55mm F1.8 on Sony Alpha 7R.
Wide open F1.2 vs F1.8:
1) IMO, those numbers are not directly comparable across the system. Check the same lens data in two different camera and you will see the difference (e.g. Nikon 35 f1.4 G on D800 vs D3x)

2) While FE55 shines in all the charts, the difference is not large in real-life situation. I compared M50 and FE55 in Sony showroom for considerable time before deciding to get FE55, however my key reason was AF for street shooting rather than the IQ difference.

In 1980 Color Photo in Germany did a comparison test of many of the 50/55mm f/1.2 lenses:

Discussion and interpretation of the charts can be found on MFLenses.com:
F1.2 Normal lens comparison

The charts and results (in German):

even if you have the most expensive equipment, that still doesn't guarantee good photos.
or rule out ...

...great photos from inexpensive gear.
