New guy - new R3A

johan,

Well that packaging sure looks safe. I always wondered how Cosina managed to keep prices so low. Now I know they are at least 100% dedicated to them. 🙂
Hope they are not getting insurance claims from the dealers for faulty gear thanks to cushioning their packages with what apperas to be two layers of effing drawing paper.


But anyways, do you have more scans of the 40? The bokeh in the pic of your daughter(?) playing outside looks really funny (spell=ugly?), whereas the inside furniture shot is nothing near as bad.
The lenses rendering of OOF areas seems to be higly dependent of the distance to the subject I suppose, although I haven't yet experienced this on any other lens.

It is almost annoying to see so many shots of the 40 substancially varying in character, I remember seeing some on PN, shot wide open and the bokeh looked much like the 1st version summilux. Yet some others including your outdoors shot, are nothing like it. I reckon there is a difference in COATING between the SC and MC version, but the optics are the same are they...

Also, the 50 Nokton is sometimes mentioned as producing harsh unpleasant bokeh, but I haven't heard anyone complain about the 40 when it obviously is much more prone to this "feature"..
Seems like I'm gonna buy the 50 instead...

cheers,
phil

Interesting observation, Phil. did you see Mike Johnston's (first to write about bokeh in USA) comment on PN regarding factors that influende bokeh? something like this:

1. width of aperture

2. distance to subject

3. distance of background from subject

4. contrastiness of background

Your comment certainly seems to fit with this.

Just put 4 images up my gallery 😀 that pretty well show the bokeh qualities of the 40/1.4 I had. Distance and especially contrast are the important factors if you ask me. That outside shot makes me feel sick...
 
Yeah that'd qualify as some pretty funky looking bokeh in my book. Looks like how I feel after too much double-extra-shot cappuccino.

you can get perfectly good adapters from Merkle Camera in Canada for US$30. 🙂 No need to pay $55.

Nah, only the best is good enough... Well, ok, the most expensive. 😉
 
LOL Johan! I have one of those too, its on my 21mm Kobalux lens and it cost a fortune! 🙁 The adapters sold by Merkle are beautifully made and come with a key for unscrewing them from the lens. They are made by Marumi and if you want to pay $55 for them you can - Marumi OEMs them to Adorama who sell them for $55. 😉

I like your signature GIF by the way... 🙂

Now I feel I really did make a good deal buying the 15/4.5 for 315 € as this was included. Also nice original Leica pouches for both the lens and VF! And the lens is of the limited 100 Jahre 1900-2000 series. Not that it would make any better pictures...

I like your signature GIF by the way... 🙂
Thanks. One needs to have something to do at night... Adobe Imageready made it easy and fast as I actuallyfigured out how to do it the easiest way before I started 😛

So, Peter, I take it that the adapter sold by Adorama is better than the one sold byMerkle. You get what you pay for, right? 😀

The chair behind the hifi kit has a similar effect on me. The LHS almost looks like it it moving up and down and you've caught a double image - yeuch! 😱 One question: are you getting donut-like OOF images of bright pinpoints?

I think what the 40mm is doing is giving "ni-sen" - double line streaks. Caused by a OOF point of light being rendered as a bright ring, as opposed to a disc or (best) Gaussian spread. The Leica Noctilux gives a similar effect in some pics that I have seen of it (no, I don't own one!) which makes me wonder if it is a fundamental optical problem associated with making very fast lenses of this focal length.

Ni-sen is nothing new; see HERE for a picture of HCB with the double image effect in the background again. A useful resource on bokeh (see double twig images at top of page especially) is HERE.

Not a lot one can do about it except change the f-stop so that the background is no longer OOF (!) or open it up so far that it is so out of focus that everything smears together.
