Voigtländer 75mm f/1.5 Aspherical VM

Still waiting for some serious (or even minimal) info: weight, price, maybe mtf charts or sample shots. That rumor stuff has been around for almost 3 months with no update.

I'm more impressed by the pictures a lens takes, than pictures of a lens. "Gear porn" doesn't excite me. ;) But at least it is crisp and clean and "industrial" in design.

However, I'm using the f/1.8 version, and once I got used to its quirks, enjoy it a lot. This new f/1.5 does seem to go down to 0.7m, which is a definite plus for me in this focal length for studio (food/fashion/still-life) work. If it can replace both my c/v f/1.8 (focus to 0.9m, but light-weight) and my Summilux (focus to 0.75m, but 590g and bluddy expensive), I could get excited.

Yup, an exciting announcement indeed : I like the focal and enjoy my Summarit 2,5 (the Hektor is not for regular use… :rolleyes:), and it's years that I dream to have a Summilux… but prices don't seem to go down a bit.  This new CV frankly is a temptation… let's wait for more info & tests...

I have no idea why they do not produce the aperture like 1.4 or 1.2...

1,4 would be too much "face-to-face" with the mytical Summilux ;) … and a 75 at 1,2 I think would pose serious problems of intrusion in the OVF for front element' size (let's see if they make a hood for the 1,5... it could be problematic for OVF)

350g!? Must be using a lot of aluminium. Their f/1.8 is 420g or so.

Optical design seems to be an adaption from the 50mm f/1.5, with an additional element in front of the aperture. (Which is fine - Mandler's 75 'lux and Karbe's 75 'cron were adapted from their own 50 f/1.4 designs.)

Based on the sample shots (especially the non-human subjects) and some other C/V fast lenses I've tried (28 f/2, 35 f/1.4, 75 f/1.8) - I'll go out on a limb and predict it may show notable curvature of field.

Which is not necessarily a bad thing, if one keeps the main subject centered - it will make background corners/edges even more out of focus, and emphasize their blur/bokeh. And, used knowledgably, can extend apparent foreground DoF a bit with a sloped subject (as in the sand-dunes-bush and "still-life with egg" pictures) while putting the background even more OOF. But use f/11 if you want "sharp everywhere" with a flat subject

$1200 - reasonable for the specs. A Nikkor 85 f/1.4 G runs $1500±.

Looks like a very usable lens, along the lines of the Summilux. I never got along with my 75 Lux, even though I loved the concept of it. One of the lenses I don't regret selling. Reading the translation on Leica Rumors is painful!

The lens has the narrowest DOF scale I've ever seen. Is it usable to anything? How can it be much narrower than the 75 Summilux? Because of a shorter focus throw?

Probably - the left-hand f/16 mark on both falls "halfway between" the infinity and 5-meters marks. The C/V focuses to 2m with about 2cm of ring movement, while the Summilux focuses to 2m with 3cm+ of movement.

Doesn't appear any more useless than the DOF scale on the 75mm f2 APO, LOL.

I would imagine you just need to pick your focus spot, go there, stop it down if you don't want the DOF totally razor thin and learn how much you need to be stopping down with experience.

I definitely see having one not all that long after it's available for me to buy.

Looking at the literature for Leica's Summilux cine lenses, they seem to make that a virtue with their term, "Focus roll-off."

Do you include the more recent f1.2 35mm, 40mm and 50mm lenses in that statement?

One man's "fault" is another man's "feature".  It's all in the 'marketing skill'. 😇

No experience with the 35 f/1.2 or any C/V 50s. Regarding the 40mm  f/1.4, which I used briefly (in the M9 era), its field looks fairly flat to me (lots of aberrations nearing the edges, but not focus shift).
