The one you indicated in your post is a CSP Ser III 25mm, I assure you that front piece of glass is a convex front element.  

Maybe that's the problem causing the blue flare – LLL left out the front element and used a UV filter instead 🤪

A question to all owners:

Would you still have bought this lens had you not known it is based on a Cooke Speed Panchro?
If LLL would just label It as an ordinary 50 and not a SP emulation formula?

To paraphrase: Would you still have bought this lens solely based on its performance?

I am curious.

 

The desire to own a replica of a famous cinema lens is big part of why I got it. The glow at f/2 while maintaining sharpness is why I’m keeping it. It’s essentially a 50mm f/2 version of the 35 Lux pre-ASPH v2. 

I would never search for, buy, CLA, and convert an original SPII to M-mount otherwise. I wouldn’t go through that ordeal since the image circle of the original SPII only covers an S35 sensor. The fact that LLL scaled up the design for full frame  is pretty cool.

This. Yes, the cinema lens design label was a big draw for me.

In other news: There seems to be a 75mm f/2 Speed Panchro II in the works as well! Got an Email from LLL today.

No, not really. I simply bit the Ted's "special/cinematic/etc." rendering bait. But, again, I'm not the regular Leica user, who owns 5 versions of the same 50mm "Summiwhatever" lens. Actually, I'm not a Leica user anymore. And I saw no reason to adapt this lens to any other system, to be perfectly honest with you.

Fact checking the Snake Oil Salesmen on the internet, “The Cooke Speed Panchro Ser II only covers S35 sensor”… apparently that is a lot of “Bull”?

Could you share a comparison? Stills or video. No one has shown their comparison yet.

Yes, if there is a URL that will work with this site.  Most of my files are 4K video, though there are always screen shots.  It might take a couple days to fit it all into the schedule:)

Yes, I did mention that (see post #9), but it seems like said salesmen have more credibility than actual users...

Edit: see post #21 as well

No need for name calling, I’m just some random person who by a stroke of dumb luck got to try the LLL SPII prototype and later bought one (and almost returned it).

Does your original SPII 50mm give you sharp results corner to corner at f/8 and infinity on full frame in the full 3:2 ratio? Does it have hard vignetting at infinity and f/8? Edge swirl? The original SPII full frame coverage tests online: I’m only seeing them shot wide open and with a 16:9 crop for video.

Please post some example shots with your original SPII vs the LLL at infinity at f8 with 100% crops of the corners and center.

Here’s what I’m talking about above. This person tests a SP 50mm original and says it “covers” full frame. But they’re talking about video use: 16:19 crop / wide aperture / close distance / central subject / etc.

“Coverage” can mean different things for different purposes. A lens that “covers” full frame under the above conditions doesn’t necessarily mean “coverage” for infinity landscape for example.

Thanks for finding these. Hard to tell about the details from the resolution provided, but they do show that hard vignetting is not an issue with the original on full frame.

Looks like in the first ones, the distance of the scene exceeds the DOF of the chosen aperture, so we can’t evaluate those. The last one of the wall is at a mid-distance where I’d expect an S35 lens to do ok on full frame. But the shot at the farthest distance of the tower (still not infinity) falls apart at the edges at f/5.6 and looks like the LLL at f/2.8.

Would be easier to evaluate with side-by-side testing on an 40-60mp sensor.

Looks very good for close distance. I would love to know how it does at infinity in the corners compared to the image center.

Regarding pixel peeping, ok, we have defined your use case and definition of “full coverage”, which does not include critical evaluation of performance into the corners at infinity at high magnification. This was not the purpose of the original SPII, but it does happen to be something the LLL version excels at.

My upload was at infinity focus.

The entire scene needs to be at infinity to see how the corners perform at infinity – your image has the corners out of focus. The edges left and right look good, but hard to tell from a screenshot taken from video resolution. To evaluate for landscape purposes, the screen shots need to be at least at 1:1 / 100% magnification from an original RAW file without too much sharpening applied.

Here I show the LLL SPII at infinity f/8 in the center / edge / and corners.
