TheEyesHaveIt Posted September 11, 2024 Share #21 Posted September 11, 2024 (edited) Advertisement (gone after registration) 11 minutes ago, Derbyshire Man said: My testing so far is that the Nokton is a PITA for off centre portraits. The Summilux is good and sharp centre and also pretty good off centre, the curve of the focal plane means the standard deep breath is needed to be sure of focus as it tends towards back focus laterally at portrait distance. The Thypoch is however spot on without any moving backward or forward for centre or off centre. However I like the rendering of the Summilux best (I'm a black and white shooter), I don't like the infinity lock on the Thypoch, I'm not sure it's focussing well on infinity when wide open and I hear there's a revision on the way without the infinity lock. More testing in 30 minutes. Desperately trying to save myself money! Thanks for sharing - you are one of the few individuals that have all three of the fast 28 lenses at the same time! I've liked the rendering of the Thypoch from the shots I've seen, but none do a direct comparison to the Summilux. If you're able to share any of those, that'd be great! I too would love to save a few grand plus have a smaller, lighter lens! Edited September 11, 2024 by TheEyesHaveIt 1 Link to post Share on other sites More sharing options...
Advertisement Posted September 11, 2024 Posted September 11, 2024 Hi TheEyesHaveIt, Take a look here 28mm summilux second hand vs Norton 28mm 1.5. I'm sure you'll find what you were looking for!
LarsHP Posted September 11, 2024 Share #22 Posted September 11, 2024 Regarding field curvature in the 28mm Nokton I owned, I never found it outward bending, even when testing for it. The lens has noticeable optical vignetting, though, which in some cases looks the same. https://www.fredmiranda.com/forum/topic/1842505/20#16463634 1 Link to post Share on other sites More sharing options...

Derbyshire Man Posted September 11, 2024 Author Share #24 Posted September 11, 2024 Off centre CV, Summilux and Thypoch (sorry order seems to be random!). Shot was taken immediately after the straight on with just rotation. Summilux and Thypoch were in focus, CV had dropped back (which is what one would expect). The amount back focuses is more than I've experienced with other lenses and of course variable dependent on focal distance. Welcome, dear visitor!

TheEyesHaveIt Posted September 11, 2024 Share #25 Posted September 11, 2024 The CV is a bit sharper in the center (assuming focus was nailed on all). But even with the centered shot, the sofa arm is not as blurred in the CV shot, which seems to indicate the above discussed issue of the field curvature and/or optical vingetting. Also notice some slight color differences between these. Thypoch seems softness in the center. Link to post Share on other sites More sharing options...
Derbyshire Man Posted September 11, 2024 Author Share #26 Posted September 11, 2024 And landscape wide open. First the CV is much less wide than the Summilux, there was some difference in position but even so it is noticeable. Welcome, dear visitor!

I checked other images for camera shake but it’s repeated in all. The Summilux has more interesting monochrome rendering, more detail wide open, excellent central sharpness, predictable off centre focus behaviour. All of which is somewhat annoying. The only thing I note in the images is that the bokeh in the other lenses appear larger even once variation in angle of view is taken into account. Which has got me wondering whether f1.4 in the Summilux is actually equivalent to 1.4 in the Simera. More very amateur testing for tomorrow.

From these shots, I’d prefer the middle shot, which is said to be the Summilux. First the young man is smiling 😉, second it seems to brighter (assuming all things equal), and lastly it’s visibly warmer than the shot above and a tiny bit warmer than the shot below. The cooler rendering is a feature/bug that most CV lenses share, and which I believe comes from Consina’s Zeiss heritage. Could be wrong, of course. But the cooler rendering is undeniable there. The Thypoch is considerably less contrasty and darker than the Nokton and Summilux, basically the outsider here. If I had to choose, I’d take the 28mm Elmarit ASPH, and from this bunch the Nokton, as I don't shoot 28mm often/never and would not get my wallet convinced to buy the Summilux. But it is indeed a class of its own, with the Nokton a highly convincing second. Link to post Share on other sites More sharing options...
Derbyshire Man Posted September 12, 2024 Author Share #32 Posted September 12, 2024 We all have different usage cases, if I was mostly occasional landscape I'd just stick with the 28mm ultra F2 mk 2. But my experience with the Q2M gave me a significant taste for environmental portraiture with a 28mm lens. The unpredictability of the CV Nokton off centre would make that pretty hit and miss for my style of photography where I mostly seek to avoid the subject slap bang in the middle of the rangefinder focus patch.

Thypoch, CV, Summilux Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! The Simera has clearly more blur when looking at the background through the window, and smoother bokeh, but that of course is a matter of taste. When I tested the Nokton near MFD with focus away from center, sharpness was simply bad, while the Simera looks good. Not a surprise, given the latter has FLE, while the Nokton is a block focusing design. Edited September 12, 2024 by LarsHP Link to post Share on other sites More sharing options...

To me, these crops (I assume) show that focus is placed markedly further away in the Simera shot. There may also be a difference in field curvature and optical vignetting, but with such a big difference, I bet the focus is not placed at the same distance. Again, assuming these are crops (from the foreground). Link to post Share on other sites More sharing options...

That the Summilux across most of the image has higher resolution at 1.4 (although of course whether that is of much use is another question!).

LarsHP Posted September 12, 2024 Share #36 Posted September 12, 2024 Indoor test shots with Thypoch Simera 28mm f/1.4 (first) versus Voigtländer Nokton 28mm f/1.5. Both wide open. Focus distance about 1.5 meters. Note that, while the Nokton has slightly better contrast when focus is in the center, the Simera clearly has the upper hand when focus is placed away from center.

LarsHP Posted September 13, 2024 Share #39 Posted September 13, 2024 (edited) Landscape @ f/1.4 in broad daylight? Yes, some of us are silly enough to do that! Thypoch Simera 28mm @ f/1.4. Center crop is in 100% from a 24MP camera. Sharp enough, in my book. Note that the background isn't in focus. I thought it would be more visible, but it's not seen unless viewed in 100%.

tom0511 Posted September 13, 2024 Share #40 Posted September 13, 2024 For me the Summicron is the best all-round 28mm. I don't bring the 28 Summilux often. For some reason I also love the 28/5.6 Leica, fun lens and while corners are not great the overall look is special IMO. 2 Link to post Share on other sites More sharing options...
