Some even for known camera issues.. however for someone trying to do photos, the forced AI editing isnt wanted. I would not call that real computational photography, since it seem to be only some minor distortion to be corrected. Real computational photography creates artificial content based on what the software/AI imagines as probable. Basically all of today’s smartphones work that way by taking several pictures from multiple cameras/focal length etc. Link to post Share on other sites More sharing options...

Most are just transformations placed in the DNG file which then are applied by the algorithms implemented in the editing software. No AI at all. Been so in Leica's Q line since the first model. = lens in my beloved Q343 being an "educated dud"  ? Impossible to verify and don't care: I'm very happy with it  Link to post Share on other sites More sharing options...
farnz Posted March 14 Share #23  Posted March 14 With reference to the OP's post re APO lenses, I use the 280/4 APO-Telyt-R and the 100/2.8 APO-Macro-Elmarit-R and in my opinion they are both still class-leading despite the modern technological 'improvements' that have come to pass. (I must admit that the Leica 90-280/2.8-4 APO-Vario-Elmarit-SL produces some exceptional pictures that keep nudging me to acquire one.)

topoxforddoc Posted March 16 Share #24  Posted March 16 (edited) The 280/4 APO-Telyt R is still stellar and works well on digital. Here is my 280/4 APO Telyt R with 1.4 x APO on my S(006) using the Leiko adapter Settrington Cup at the Goodwood Revival 2016 My friends Charles & Kate Knill Jones in his racing A40 at the Goodwood Revival 2016 Welcome, dear visitor!

lexffm Posted March 17 Share #25  Posted March 17 (edited) I can also confirm that a whole range of R lenses are truly amazing. I inherited some from my father, such as the 80 f/1.4 and the 100 f/2.8 Apo-Macro. Then I bought the 280 f/4 Apo-Telyt and the 180 f/2.8 Apo-Elmarit. Not only are the latter two extremely easy to focus, I'm always impressed by the superb resolution, even with a strong crop. I also considered buying the 180 f/2 Apo-Lens, but without a monopod, it's out of the question, at least on the M, which is where I usually use it... Here are a few examples: M 11-P with Apo-Telyt-R 1:4 /280, ISO 1250, f5.6, 1/1500 Welcome, dear visitor!

erl Posted March 17 Share #27 Â Posted March 17 Advertisement (gone after registration) Yikes! That is a big bugger. I have the 70-180, 2.8 elmarit. It is a big heavy bugger too, but it shoots superb images, even wide open. 1 Link to post Share on other sites More sharing options...

Some nice gear floating to the surface of late though. Link to post Share on other sites More sharing options...

When it was hooked up to my DMR, it produced some stellar shots. DoF at F2 is razor thin, but a ground glass Brightscreen in the R9 made focussing in low light a dream. No need to lift weights when you hand hold this. Here's a shot of Billy Cobham from back in 2014 at the Cheltenham Jazz Festival. 180/2 R9/DMR hand held 1/45th sec to get the blur on the sticks.

SJCoates Posted March 18 Share #30  Posted March 18 Here is a photo taken with my new favorite thing, the 400mm f/2.8 apo Telyt-R; the Middlesbrough transporter bridge, a bit of an iconic landmark. This is with the lens fully open at f/2.8(cropped a bit to get it to post on here). The bridge is around 1 mile away. I still can't get my head around the fact that I have this thing, to say it is a dream come true is a huge understatement. This photo was actually taken from a nature reserve; I am getting used to allocating quite a bit of extra time to take photos as the lens is quite a talking point! Welcome, dear visitor!

SJCoates Posted March 18 Share #31  Posted March 18 And another one, this time adding the 2x apo extender, so 800mm. This is at Seal Sands, Teesside, near where I took the photo of the bridge. Apparently this is the only place in the whole of Europe where seals have returned to an area that was heavily polluted due to industry. Again this photo is heavily cropped to get it small enough to post on here. For reference, the seal is probably around 100m away. Welcome, dear visitor!

Tirpitz666 Posted March 28 Share #32  Posted March 28 I can confirm that the diminutive 180 F3.4 Apo-Telyt is an outstanding performer even on the 102MP sensor of the GFX 100s, which is quite an amazing feat for such an "old" lens 🙂 2 Link to post Share on other sites More sharing options...

bags27 Posted April 14 Share #34 Â Posted April 14 I used to own the 180 f/3.4 APO and thought it was a tremendous lens, even with the 2x APO extender. I shoot mainly with Blads now (mostly film; a little digital) and the 250 Superachromat with 2x mutar I think is equally impressive. 2 Link to post Share on other sites More sharing options...
rubidium Posted April 15 Share #35 Â Posted April 15 I regularly shoot with R lenses on my SL-2, using the Leica R-to-L adapter, after my DMR finally gave out. Since this topic is about the APO R lenses, I'll simply say that my most beloved lens is my 100/2.8 APO-Macro-Elmarit-R, closely followed by my 280/4.0 APO-Telyt-R. With such stellar quality, I don't see ever giving these up. On 3/17/2025 at 3:41 PM, gbealnz said: 70-1 Â 2 Link to post Share on other sites More sharing options...
