in these days I'm reading this book
It's about "how a figure works" in terms of composition, and it's incredibly interesting. Unfortunately I think it's only in italian.

half hour ago I was reading a book about "composition", and this is a perfect example of the "repoussoir" I was reading about.

I've been for one year without photos...
This lockdown will result a sort of gap between 2019 and 2021.
This is the last photo I've made, 10 months ago.

it has the same characteristics of k7 issue. With BG mounted on, the problem is reduced.
There will be a sort of resonance frequency giving blur as result.

Pentax k7 has the same problem at 1/125 s. Adding a battery grip there is an incredible improvement.

the tokina-pentax projects for aps-c lenses should be: 10-17, 12-24, 16-50 and 50-135.
I think that Hoya, the owner of pentax and tokina brands between 2007 and 2011, moved some technologies (inclunding lens coating) between the two brands, and the innovative coating on the frontal lens of tokina 50-135 sounds too much similar to the SP coating on the frontal lens in pentax 18-135...
Furthermore, the 16-50 tokina for canon is "sdm", for nikon is screw-driven. Pentax 16-50 has the possibility to be converted in "screw-drived".
The 10-17 pentax is not SDM, and the same the 10-17 tokina.
The 50-135 tokina has the ultrasonic motor but not the screw drive, like the 50-135 pentax.
Conversely, the differences in 12-24's are bigger: the pentax has 8 blades, the tokina 9 rounded blades.
What makes me perplexed about actual "tamronisation" of Pentax is the fact that in the past the common lenses were sold branded tamron and pentax (I had a 18-250 tamron). Now new tamron lenses are not avaialable for pentax.
In the past Sigma lenses were more or less all available for K-system. now...
Tokina lenses continue to be produced only for nikon and canon mount...
Just this. I hope that the present agreement with Tamron is not blocking any future development of k-mount system.
We'll see... :)

I mean Tamron lenses simply branded Pentax.
I can understand one or two lenses, moreover superzooms or similar, but not every new lens.
This situation recall to me the "adventure" of samsung in reflex market, with pentax re-branded material. The end is known.

it seems that 85mm f1.8 tamron is coming....
I don't know if this "tamronization" of Pentax brand is good or not.

Hi, Alex!
did you notice the same blur due to the "resonance" of the body with the movement of the mirror/shutter also using heavier optics?
The k7 has a similar problem, partially solved by increasing of weight with the BG.
