Lovely shots. I like how the lens performs here even though your skill surely shines as well. This is exactly the type of use I envision for the lens, so these samples are super useful.

Thanks Steve! I really like this offering by CV—and glad the photos are illustrative. The only things that’s quite tricky about this lens is that short focus through—it’s painfully easy to slightly misfocus.

Would you agree that focus sensitivity is comparable to using the Voigtlander 75/1.5 Nokton? Although some people find it challenging to focus with the Leica 75/1.4 Lux, I find it to be the most effortless to focus among all my 75mm lenses. It has a very long throw but I get very accurate results. Luckily my Lux is well calibrated with the RF when shooting wide open.

^ The challenge with the 75 1.5 focusing for me was the focus resistance was so fluid, I was constantly moving the ring accidentally after I had focus achieved. But for actual focusing, it found it much easier than the 75 1.9 for some reason. The heavier focus resistance of my copy of the 75 1.9 makes it very unlikely I will accidentally move focus, but it makes it harder to tweak in tiny increments back and forth. It's loosened up some since I got it, hopefully it loosens up more.

I do think that smaller movements of the 75 1.9 focus ring move focus further than the 1.5, which adds to the difficulty of fine-tuning focus at the smallest increments.

Yeah, I agree. I had 2 copies of the CV 75/1.5 at different times, I found them both hard to focus. Not brutal, but a challenge on an RF and EVF. No really on resistance as much (mine were slightly light resistance), more on account of short focus throw + large aperture.

I actually find the CV 75/1.9 even harder for some reason when both shooting wide open, at least on the a7r2. And both of my CV 75/1.9 have very little resistance--less than my 75/1.5's to my memory. I think the increased DOF from the 1.9 makes it trickier because the 1.5 gets a bit more separation/pop when the DOF is thinner. That's my theory anyway.

And yes, I found the 75 Lux, substantially easier to focus than the CV lenses with fast throws, on RF's and EVF's.

Got some photos back on film with the 75mm f/1.9. Shot on Kodak Vision3 500T (dev'd in ECN2 chems at a lab here in NYC) on my Leica M7, with an 85B filter. I think the lens looks great on film! Better than I'd expected. I love my Color-Heliar 75/2.5, which does have a lot of pop, but this feels like it's resolving finer details. However a number of my shots had a weird blocky kind of flare in them. I didn't have the hood on, but I may have to start bringing it along.

Most of these were shot closed down (5.6 to 11) since I was shooting on a bright sunny day at ISO 320 and my M7 tops out at 1/1000th, except for the bunny ears shot which I believe was f/4, and the shot of my dog on the bed which was wide open at f/1.9. I was surprised that at f/4 the bokeh on the bunny ear shot still appears mostly round (I think there is just one bokeh ball in the cab on the left where you can barely see a little roughness from the blades).

Great set—3rd photo in particular is gorgeous. The big blob flare I’ve noticed happens with the sun just outside the frame. With a small shift of the lens, in can be avoided entirely.

Thank you!

That's good to know, I wasn't certain if it might've been an internal reflection from the filter. I find I do shoot a lot with the sun just out of frame. I'm curious to see whether the hood is long enough to mitigate it or not!

In an urban environment you might also have some reflections that are bright enough in their own right to cause flare problems. I kind of feel that's what happened in the bottom right quarter of #4.

The roundness of bokeh balls at f/4 likely won't show the aperture blade shape when they're more diffused, like the majority in that photo. The two specular highlights in the photo however act more like collimated light and will more clearly show the aperture blade shape.

Regarding focus speed: while it would kind of defeat the small size of the 75/1.9, I wonder if adding a relatively thick ring around the focusing ring would increase its diameter enough to allow somewhat more precise, slower adjustment? For example there used to be a site called Leica Goodies that sold a product called 'steer' that basically did this. Unfortunately I think the site is no longer around. As discussed a while back, my feeling is my larger diameter lenses with the same angle of focus throw as narrower diameter lenses are easier to focus, whether via RF or visually via EVF. Another compounding factor for the 75/1.9 might be its wide open residual SA subtly blurs the plane of focus compared to a higher contrast, better corrected lens, making visual focusing via EVF potentially more tricky when combined with the fast focus throw.

I have both the 75mm 1.9 ultron and 75mm 1.5 and find them about the same to focus accurately. Still cannot decide which I like more in terms of IQ..

I have more problems focusing with the Leica 90mm f2 APO lens but I think I just need a little more practice with it.

That's going to make me rethink getting the 90

What's interesting is the shots I posted above look exactly like the 75 1.5 to me (used to own it). When the background is far enough behind the subject, they are difficult to tell apart wide open.

What sold me on the 1.9 vs rebuying the 1.5:

0.5m MFD
Smaller
Lighter
More attractive black finish options
Ergonomics
Design
Hood is not as ridiculous

I like the 1.9 so much, I may buy the SC version so I have both.

I agree with all your advantages.. .. but vs a 2/3(?) stop difference.. I think I just need more practice with the Leica 90mm.. One option is to go with the 75mm and then get a 135/3.4.

When shooting with the Leica 90/2 AA, I have found that using the rangefinder results in very precise outcomes. I believe that having both the lens and rangefinder in perfect synchronization is crucial in achieving such results. To confirm this, I recommend testing the lens and ensuring it's calibrated perfectly with your camera body. If you opt to use Live View instead, you should be able to achieve sharp images consistently, provided you use adequate shutter speeds.

Fred Thanks.
I did just check and they are aligned--shooting a wood fence and some bricks. I went back to look at what I missed and I realized I was taking some flower shots at pretty close range and there was a little bit of wind.. So perhaps that was the problem.

I don't think anyone has yet. It's probably similar to the 75 1.5, which I posted some samples of on the GFX in the review thread for that lens. I don't have a GFX at the moment to try it with the 1.9.

Does the 75/1.5 cover the entire GFX image circle at portrait distance? I know my 75 Lux didn't--died with hard vignetting between the FF and MF zone. My little Sonnetar 73 covered it well, and without that much additional vignetting even.
