I had a play with the 18mm Samyang today in WEX (I didn't even know it was available!) - and it seemed very like the other pancake lenses - built to its price.
But for less than £350 it seems incredible for a good ultra wide!
Re-joining the K1 club... picked up a K1ii at my local WEX Open Day - should get it tomorrow / Saturday
I've been wanting to scratch my full-frame itch again and get out and about preferably with a 35mm lens - was either this or another A7R2 for the same price.
I have to say that even at £1600 I think its probably overpriced, as Raymond says the D750 is a much better value.
I wouldn't say they're dead yet but I suspect its only the higher end (D850 and D5) that will ever see another update now.
I have to say though for someone starting out - the value in FF DSLR kit just now is unreal, certainly the used values of some stellar bits of kit have fallen through the floor, £650ish for a D750 is incredible for a camera that really isn't a slouch v similar newer models, the D810 as well for...
Don't discount the 3rd party 24-70 f2.8 options either, the original Tamron 24-70 f2.8 is slightly smaller and lighter than the Nikon but also has VR - it was almost always on my D750/D800 when I was a Nikon user, its also fairly cheap used - potentially as low as £400.
I should clear that up - I really meant that I felt their used to be a feeling that Tamron stuff was better, before the Art Line of glass (which is better than even some of the Canon, Nikon stuff).... not so sure its the case now.
I think traditionally Tamron were seen as "better" than Sigma up until the Art line of lenses was introduced, their primes are close to if not equal to the equivalent Canon, Sony and Nikon glass.
Tamron do tend to be more focused on Zooms rather than primes too wheras Sigma have done the...
I read that its been developed for mirrorless rather than DSLR to Mirrorless like the others - possible Canon RF / Nikon Z mount later?
In saying that based on size you'd think it wouldn't be too hard to make a NIkon F or Canon EF version..
