Thank you for this link.

I'll check Foto Den Boer again!

The new copy arrived today!
I couldn't take many pictures, only a couple wide open on the way to work..

 

[nutmeg]

but misfocusing again :-/

I don't have both to compare how this copy is back focusing compared to the other. In some cases it is ok but in most it is not optimal.

I just did a little test to see how it works with my M9.
I took 20 pictures with each lens wide open of this record at very different angles, hand held (1/180s), always focusing on the hole and this at about 1 meter away.


Maybe not very scientific but it gave me some informations:

With my copy of the Summicron v2 it was sometimes very slightly front focusing but in most of the cases this was ok, like this:


Same for the soft Summilux 35 pre asph:


The Summicron 50 v4 was always right, like this:


And the Ultron:








Now I don't know how disturbing this is in "real life" , maybe not that much, maybe more..

Ps: don't pay attention to the light, it was very overexposed and I had to darken the pictures a bit in order to see some details.

That's a bummer. Judging from your pics, focus can't be off by much.

But two out of two... I'd be more suspicious of the camera than the lenses. Can you get your RF checked somewhere?

Or pack up all your lenses and camera and send them off to DAG 😉

 

[nutmeg]

Anyway not bad compared to the auto focus on my Canon 5d2/24-70L 😀

I'll come back with more useful comparative pictures.

I'll try the Leica store in Munich tomorrow. Maybe I could even test the lens on an M240 or M10..

I could also try to live with the lens working like this, it may give me some nice pics..

Thanks for the additional photos and looking forward to the comparison shots. I was just in Munich in February and had ~5 days of sun and nearly 15 degrees. Nice to see the blossoms blooming!

FWIW, my copy of the VM 35/1.7 back focuses a fair amount on my M240. But it's consistent, so I just offset the rangefinder alignment by an amount I determined after many test shots. I can hit correct focus as consistently as I can with any of my other M lenses. The M240 was recently overhauled by Leica and the RF was recalibrated, yet the misfocus with the VM remained. The camera's RF works nearly perfectly with most of my other M lenses, but if I'm extremely picky shooting wide open, some of those also require slight tweaks, usually to offset slight back focus.

It looks like your 35 Cron and 35 Lux slightly front focus. More so the Lux.

I took some random pictures today and it needs more tweaking to hit the focus but it seems to be usable.

Some bokeh test..

It's hand held and the framing is every time slightly different so don't try to zoom in to apreciate sharpness.. but the character of each lens is distinguishable.
All from RAW, the only modification was the WB, set to "daylight" in Photoshop.

Btw, the new lens is here in Amsterdam extremely expensive, over EUR 1.200,00 at Foto Den Boer. The VM f/1.7 (black or chrome) is only about EUR 800,00.

That’s odd... In Aus the new 35/f2 is $200 cheaper than the f1.7 ($995aud, which translates as ~630 euro)

I called them one minute ago. There is an error, the price of the Utron at Foto Den Boer is EUR 745,00. They've put the wrong price on it - EUR 1.200,00 - in the display in the shop, no doubt by mistake.

So, is the 35/1.7 more expensive to buy than the 35/2?

Here in Amsterdam I think so, but not by much.

[rscheffler]

Depends where you shop. In the US, the two lenses are nearly the same price, with the 35/2 $20 more at $799. In the UK, the 35/2 is £100 less than the 1.7 at Robert White.

I no longer remember what the 1.7's introductory price was in 2015, though I do remember buying it from an Austrian dealer for about 625 USD, which was considerably less than the US price at the time and made the purchase worthwhile. It seems worldwide price disparity for that lens has somewhat narrowed.

In Germany it's approx. the same, maybe 50€ difference in favor of the f2 version.

I'm still uncertain, to change my f1.7 against the f2 🙁
The last pictures I saw here, show a bit more nervous bokeh of the new one.

For me actually it looks like this:

Ultron f2
+ size
+ focus stick (very big point)

Ultron f1.7
+ half stop faster; I could live without it...
+ better Bokeh?
- no focus tab/stick

In my region it's a problem to find a local dealer for a comparison between both.

WW distribution is a big problem vor Cosina, I think ...

In Europe Cosina is related to RingFoto, headquarters in Germany. The items are only for sale in related shops. This is what I understand. Other dealers can buy the stuff and resell it. Related dealers get all the stuff and can put it on display in their shops. I guess this is how they work.

That's right, but most of the local dealers dont't have the CV lenses in their local shops!
You can order them online, but not test directly.


I think it is the same in the Netherlands and all over Europe - Unfortunately ...

No, in Amsterdam is one shop that has almost all the items on display. You can try them out. That shop is Foto Den Boer in the 2nd Hugo de Grootstraat. Great folks.

But outside Amsterdam this will be difficult.
