Next OL lens test report - Viltrox PFU RBMH 85mm f/1.8 STM
Very affordable and pretty good

Note: Tested at 26mp on the X-T30

Thanks for the review, Klaus!

Very interesting lens indeed, especially given the price.

Do you also plan on reviewing the other 3 Virtrox in the series? 23 f1.4, 33 f1.4 and 56 f1.4?

Thanks for the review, seems like a great budget portrait lens.

-Going forward, how will resolution scores generated on the X-T30 compare with scores from the older 16MP body?

-Also, I assume that the resolution scores for this lens are consistent between center and edge because this lens was designed for full frame? As if we didn't already doubt it, this appears to disagree with Tony Northrup's recent video on using FF lenses on crop bodies.
Well, on the 26mp sensor the center will be emphasized and, for some lenses - mostly ultra-wides, the border performance will fall apart.

And yes, if I can get my hand on the new Viltrox lenses I will test them.

Certainly an unusual item in the lab. Thanks for the interesting read, Klaus.

P.S. What does PFU RBMH stand for anyway. WTF LOL.
I'm rediscovering this lens. Shot with it along another lens that is 4x the price of the Viltrox, and both have similar rendering and, surprise-surprise, sharpness wide open.

Still haven't found a place to share full res photos.

On the negative side, I find the AF jittery at times (but not sure if Fujifilm is not to blame here) and bokeh in transition zones, e.g. when shooting branches, etc. up close.
The AF on Sony E-mount also hunts.
