Originally posted by Qwntm So Thomas Heaton shoots a Canon 5D Mark IV with a Canon 16-35 F4, Canon 24-70 F2.8 and a Canon 70-200 F4 for his landscape work and it's a solid kit based on solid choices.
I have been pondering how to put together a K1 Mark II kit with somewhat equivalent lenses.
The only direct swap is the Pentax 24-70 2.8, it's a direct equal (except $700 cheaper!)
For the 16-35 F4, I think the Rokinon 20mm 1.8 is a decent choice. Thomas shot with a Zeiss 20mm for years before getting the 16-35. And 20mm is a great focal length and what you need when you need a wide landscape, so no issues there for me. The 15-30 is massive, doesn't take filters easily and weighs a ton. Great lens but not an f4 equivalent for me.
The 70-200 F4 is the tricky one. I have the 55-300 WR and though it works fine in crop mode, it's weird in FF mode from about 70-170. The 70-200mm 2.8 Pentax is a fine lens, but for mobility it's not an F4 size and weight lens.
So any ideas or thoughts regarding these three, and specifically a 70-200 F4 FF Pentax lens equal? (Currently produced would be a bonus!)
Actually, I find nothing special in his kit that you mentioned.
Its just UWA zoom to telephoto zoom.
Thats like what most landscape/travel folks will have in their arsenal in one form or other.
Ok... maybe its harder to have similar due to the Pentax lineup.
The Zeiss 20mm you mentioned should be the Zeiss 21/2.8 distagon and thats a lens thats very good and a hard match optically for 20-21mm. (used to be available in PK mount)
The Canon 16-35/4 vII is also a great performer for edge performance (previous versions not so much).
Similarly, the Canon 70-200/4 is hard to rival, sharp and rather small in this FL range.
To get to as close to it for edge sharpness, really its going to be DFA 15-30/2.8, DFA24-70 and the new DFA70-210/4.
The Laowa 12/2.8 is rather small, fast, sharp, low distortion for a UWA too
However, imho, where the Pentax options may lose on edge sharpness, they often make up for with size and portability.
Most bloggers/internet personalities show you the nice stuff, but they don't say how darn back breaking it was hauling the stuff around (or that they had a crew or sherpa)
For me it would be a selection of lenses like the Laowa 12/2.8, M20/4, K28/3.5, FA31ltd, FA35/2, FA50/1.4; FA77ltd, FA135/2.8, S.Takumar 135/3.5 that will cover a 'like' focal length range.
Some are faster and no worse (if not better ) in stopped down IQ and often still smaller/lighter that the 3 above mentioned zooms.
(eg. Laowa 12, K28/3.5, FA50/1.4, FA135/2.8 );
Not to mention the option to leave most of them in the hotel since its dinner time and you only need 1 lens 'just in case'
from 135-200mm is the weak part in Pentax's lineup imo, if trying not to haul along a big/heavy f2.8 tele lens.
But this is really where that new DFA70-210/4 comes in
