A bit strange method of comparison and time to publish...The difference in portrait 0.2 points, in landscape 0.1, high ISO of 645Z is 16 points better...50 Mp vs 51.4 Mp
Why 102 vs 101...?

and...the camera is 3 year and 7 months old..

Yes. it's rather fast MF sensors. Found such info and decided to share with all users. New 150 MP 40.4x53.7mm could do 4 fps.

I think 645Z's replacement could carry 100 MP 33х44 mm because of price and 4K ability.

100 MP older 40.4x53.7mm Sony sensor is rather slow.

But who knows?

It covers FF without any serious vignetting from f2.8
EV0.4 at F2 and 0.13 at F2.8 (at APS-C) means that this lens has not any problems at FF.

Yes. It's fact. But where did I criticized 15-30? :) It's cool and sharp zoom. But big and heavy.

I prefer primes and change it than to use zooms. I've sold my FA20-35/4, by the way. It's light and not big.

To carry 1 kg zoom is not my choice too.

really sad news...
but FA31 is still in production and FA20 and FA28 was in production till 2004 and on sale till 2006-2007.

or do you mean that Pentax lost ability to develop compact FF lenses?

It's Russian Pentax club.

Did you ever see FA20/2.8 or FA 28/2.8, for example? Or Voigtländer Lenses for M-mount?

DFA15-30
Diameter x length 98.5mm x 143.5mm
Weight approx.1040g
1 KG!!!!

You can"t use any common filters with DFA15-30. Do you know it?

For example,

FA20/2.8
70 x 43.5 mm and 255 g

FA31
65 x 69 mm and 345 g

or
FA 28/2.8
65 x 41 mm and 185 g

I tried 17-40/4 USM L today - it's noiseless and superfast lens.
If DFA*50 could be the same, it's good...

But it's rather strange that first Pentax-Ricoh ring motor will be on 2018 year...
Colossal engineering lag from all another photo brands...

The users from Penta-club say that it's not easy-to-use during trips and any travel....TWO light wide-angle prime lenses could be better.

I've got a private message with such info from insider. It's PENTAX plans. The plans had been postponed and killed after deal with Ricoh.
Ricoh is a bit better ruler of Pentax than Hoya.

Ricoh's managers at PhotoSalon said that 11-18 is not replacement of 12-24.

Plan of 2010/2011 year. It's fact. Wide-angle lens for APS-C was developed many years ago. As for 11-18 - it's some new variation, as I think.
