Let's check their claims:

Easy to focus

Focus assist functions like focus peaking will help to find the sharpest focus point.
Less shaking

In-build multi-axis advanced image stabilization systems of mirrorless cameras will make you forget about blurred images due to hand shaking.
No slow shutter any more

Newest mirrorless cameras featuring advanced wide ISO settings can offer the photographer to choose a faster shutter speed with minimum pixel noises on the image.


none of them is a lens feature but a camera body feature...

You probably have to see their claims in the light of: issues of the past with a 500mm f8 lens don't necessarily have to be an issue nowadays, because of camera advancements...

Yea but have they fixed the bokeh of mirror lenses ?

From the samples: definitely no.
I find mirror lenses' bokeh horrible in most cases. Any specular highlights and it hurts the eyes.

They event went to praise its bokeh

Optical construction of the lens creates specific donut-shaped and super smooth bokeh that finds support among many artistic photographers.
It's the first time I read someone praising the bokeh of a mirorr lens....
but if soleone likes this bokeh why not ??
weird enough we are in an era where camera mirror is removed, but we have a comeback of mirror lenses

I suppose that IBIS helps with the practicality of these lenses.
I'm less sure about focusing though - even with IBIS, you will end with logs of shake in handheld mode - and precise focusing while your image is shaking to some degree ...

In my book, precise manual (hand-held) focusing reaches its limit at ~50mm. Beyond it's a gamble.

But using the lens on a tripod should be Ok.

The bokeh can work out at times but, yes, generally it is distracting. The Canon RF 600/800 f/11 aren't smooth sailors in this respect as well though. Many long tele zoom lenses are struggle.

Maybe they hope a computational engine can be used to fill the holes in the boken balls...

But seriously, Tokina can do stuff of better grade than that. Why are they bothering with things like these?

[thxbb12]

It's true that given the recent works in computational photography, bad bokeh is gonna soon be history regardless of the lens being used.
