Hmmm, strange results. The 105/1.4 is a really great lens, but the sharpness is way higher than in other tests: http://www.lenstip.com/492.4-Lens_review...ution.html

and my own test: https://www.flickr.com/photos/universal_...7769293345

Sharpness at inifinity is really good, but at portrait distance (about 2m) at 1/3 of the frame, it really needs to be stopped down:

Well... I don't think we're the only review site praising this lens...
 
How did you set up your test shots and aim for peak resolution?
 

So there's going to be a DX review as well?

 
Definitely. The DX section is my next big task.

Lenstip says the resiolution is sensational, close to the record set by an Otus. What lenstip does not do is sharpen the MTF images, which explains the difference between PZ and lenstip.

TDP crops are useless as always.

 

Cameralabs says it is close to Otus 85mm f1.4 resolution.

ephotozine calls the sharpness "exemplary".

So the Samyang 135mm @ F2 beats the Nikor(s),  in "sharpness across the frame"!  Grey market it's 509 euros here.... Wowser!

Peak resolution =/= sharpness across the frame at every focus distance. Lens rentals only uses measurements at infinity. As my tests show (manual focus with live view zoomed in), the Nikon 105/1.4 is very good at infinity, but not so great at portrait distance as the Sigma 85A and Zeiss 100/2 (just like cameralabs shows). The Otus 85 is also beaten by the Milvus 85 at corner to corner sharpness. The Sigma beats the Otus and the Milvus at overall sharpness. According to Ephotozine testcharts many lenses are really great, that's why I never use their reviews as reference material.

the cameralabs portrait image does not show the lens to be not so great at portrait distance.

As in Boolean algebra, removing double negations makes things a bit more readable ^_^

Great review, I have based  most of my lens purchases on photozone.de reviews over the years. The next day I looked at this lens in a store, heavy/expensive but still very tempting.

There's a bit more of MTF-candy by good old reliable lensrentals

 

Apparently worth the price. Maybe I really should rent one? Or maybe I should save the money and put in on the GFX-account?
