Spending a bit more time with my new to me C/Y Zeiss 35-70. I'm really impressed with the quality of this lens

'Geometric energy'
4

I was recently in a park and met a couple wearing wire contraptions on their heads. I inquired about it, and the guy told me they were for 'geometric energy'. Of course, this phenomenon has been known since the 1940's but 'it has been suppressed'. A little Googling showed me that there are others who wear pyramids as well.

Of course I had to snap a pic when were walking away, or no-one would have believed me.

P.S. I am working creating some stylized pre-sets for RawTherapee. This is my attempt at high key but washed out look. All I did for this edit was apply my pre-set and adjust exposure. C&C welcome.

Re: 'Geometric energy'

I'm intrigued. I tried Googling geometric energy but only got results for geothermal energy. I'm not convinced I want to get into it but I like the headwear.

The lily in our garden is in bloom and is quite big this year. A combination of sun and (unfortunately for us) a lot of rain.

Too bad the dog isn't wearing one, that would absolutely complete the photo

You know though, I would have. I've seen stranger things.

Those pyramids you linked are $115 each, I think I'm in the wrong business.

TimHar,
The first and second ones taken with the Rollei HFT Distagon 25mm f2.8 are amazing. The dark greys and texture of the wall are amazing, and that little splash of green in the corner adds just enough color to show off the darkness of the wall. The second is nice too, the shadows have a moody presence to them.

Canada_Guy,
Incredible! You caught some really cool light with the clouds giving those shadows.

Cappuccino with 'special' macro Mamiya-Sekor 55 f/1.4
6

So, the title warrants a bit of an explanation.

I commented elsewhere on the exceptional quality of my copy of the Mamiya-Sekor 55mm f/1.4, which is fine, and this was noted when I disassembled it to check and clean if needed. The problem is that I seem to have screwed up the minimum/maximum focusing on it.

The lens supposedly has a minimum focus of 50cm (http://mamiya-nc-m42.mflenses.com/m42_mamiya_55_1.4.htm) but after my brilliant (sarcasm) surgery, it now focuses at 20cm. This is not free, mind you, as my maximum focus was 1m90 and is now closer to 1m50. Sigh.

I will have to see what I did and play around with this to set it right, but for now, I can do a close up of a cup of cappuccino without cropping.

Well, at least this result does look very nice...

Picked up a copy of the lens myself Thursday, at a local sale; haven't had much time to play with it yet, given time and weather. Very much looking forward to the pics now!

A couple of online references called it a Tomioka lens; the build quality and mechanics feel very close to my Yashinon-DX 50/1.4, so that seems fairly credible to me. Do you have any further information?

Of the old legacy 55-58mm lenses I have acquired, it is the clear champion in performance so far. This is comparing it against a Mamiya Sekor 55 f/1.8, the Cosinon 55 f/1.4 (though the Cosinon has a smoother bokeh as a rule), the Super Takumar 55 f/1.8 (the worst of the lot), the Auto Chinon 55 f/1.7, and the Helios 44M-7 (the best of this Helios series) 58mm f/2.

I have read a much repeated (presumably from the same source) comment that the Mamiya-Sekor 55 f/1.8 is as good or even better, and all I can say is that is utter bunk, though sample variation may be a factor here. The f/1.8 is perfectly fine, but it is unquestionably a worse performer. The f/1.4 is better at f/1.7 than my f/1.8 is at f/2 and roughly equivalent to it at f/2.4.

Here are some links:

http://allphotolenses.com/lenses/item/c_443.html

Regarding Tomioka:

http://forum.mflenses.com/tomioka-zeiss-mamiya-and-55-1-4-design-t22661.html

"all of them have 3 lenses in 3 groups (typical Ultron scheme). Only the 55/1.4 lens, has 3 lenses in 2 groups (one cemented doublet). => all Tomioka (Yashica) standard lenses are based on Ultron scheme, but Tomioka 55/1.4 isn't"

I can confirm that there is a cemented doublet.

Optical design:

http://www.klassik-cameras.de/Rolleiflex350_en.html (see bottom description)

Mamiya-Sekor 55 f/1.4 design

The page's author notes that it looks identical to Carl Zeiss's Planar of the period and speculates whether the design was not sold.
