Originally posted by Sandy Hancock As far as I'm aware, the roadmap is the only information we have.
I reckon the best bet is on a DFA* 35/1.4 to complete the classic trilogy with the 50 and 85. Expect it to be exceptionally well corrected and AW sealed, but large, heavy and expensive.
That looks like the most logical guess.. They don't want to be too close to the 31, and 28 or 35 are classic focal lengths. The position of the stripe is centred on about 35mm so 28 is a remote possibility 35 is more likely. It's yellow, so * designated (not a new limited). It's on the Full-frame list so DFA* or FA* (but FA instead of DFA would be very odd for a new lens),
Weather sealed, in-lens motor and KAF4 electronic aperture would all seem to be a given if it is joining the DFA* 50 and 85 (which both have the higher AW sealing, rather than WR found in the DFA limited 21 and D-FA 70-210 f/4 no * )
There's a sigma Art lens in this range, with a wide aperture. And according to the KMP page there is a very rare m-series 35mm f/1.4 and it says specifically large aperture, which implies wider than f/2 at least.
I would like to see the DA* telephotos getting an update - the 200 is now discontinued but none of the "recoats" from SMC to HD were trailed on the road map. Really this needs to get update to the newest motor and AW sealing so it's a bit more than a recoat but not a whole new design. I'd also like to see a fast DFA* 135 SDM WR.
Maybe even see the the FA 28 back in production with an HD coating for the film camera as a low cost option for the film camera.
But the two lenses still on the roadmap have been there since 2018. Everything else on the 2018 roadmap has, I think, been delivered except for a full frame fisheye zoom which has been dropped. And it look fair length of time from naming lenses to shipping them. So I wouldn't hold my breath for these.
