Fujifilm GFX50S-2, Pixel size



After learning how to use the Leica Q2, a 50-megapixel machine equipped with a high-performance 28mm fixed focus, I attached a Leica Elmar 50mm/3.5 50years old lens to the GFX50S-2 and observed it at the same pixel size. It has a triplet configuration of 4 elements in 3 groups. If you don't feel any dissatisfaction, you don't have to carry around a heavy zoom telephoto lens, but you can get a sufficient image by cropping it later?

Fujifilm GFX 50S-2



I assumed that the kit lens would be always insignificant, but when I saw it in action by myself, I was stunned up and down.

I got the Fujifilm 50S-2 yesterday, but the excitement continues this morning.

The aspect ratio of the format is very close to an ancient 4" x 5" and the view through it's viewfinder makes me feel so nostalgic as to does myself in good days 50 years ago. The action with field camera Master Technika could be reborned on this larger format camera. I feel like that, better dream again.

It was very good to move from 135 full frame to 1.7 times wisteria format, it's above any argument.

My concept of photography lasting for 50 years will be changed completely, I'm looking forward to the future with a marvelous baby.

Turning backward





Camera lens manufacturers conduct research and development in search of the best lens performance and sell them as high-performance lenses at relatively high cost.

Single focal length lenses were mostly researched during the silver halide film era 50 years ago, so the battle is now mainly focused on zoom lenses.

The number of constituent lenses has exceeded 10, and it has become large and heavy unavoidably.

Aspherical, high brightness, anomalous low dispersion, multi-layer coating, 3-color color correction, etc. All kinds of technology have been invested in lenses that "take good pictures" and are sold at high prices

On the contrary, I thought that old zoom lens might create a work with a different image utilizing a lens that produces flare, ghost, blur and distortion.

For that purpose, the lens obtained at the Yahoo auction is a Sigma Zoom θ-3 28-84 f3.5-4.5 junk product with "mold and mist." It was necessary to disassemble the module body from the front in order to wipe the fog on the front surface of the rear lens of the intermediate lens group.

The case of the intermediate module was glued and screwed, so there was no tool to hang it, and it was difficult to separate and open it.

Stopping down to f8 sharpens the image, but at f3.5 wide open it's still blurry and blurry.

In the future, I would like to create works that make use of this extraordinary characteristic.

Equilibrium


The cherry blossoms are approaching the season of plum and player substitution, reaching their peak Spring is approaching, and all life energy is about to start its activities.

As long as I am alive, I have to set a new goal and stand up. If there is no change, if I keep doing the same thing as last year, there will be no progress. It is not interesting to live, but just boring.

Next year's theme is "Equilibrium and Peace in the Integration of Influencing Elements".

Consideration about Engine mount, A3 8PCAX


Audi A3 ABA 8PCAX 10-year-old model whose increase in NVH prompted me to replace the engine mounts.

I thought it was simply a decrease in the viscoelasticity of the rubber of the liquid-sealed mount and the loss of liquid, but as I observed the changes before and after the replacement of the parts in detail, I learned a lot and was forced to change my long lasting concept.

Absence of abruptness when braking was apparent after that.

Load transfer became gradual by suspending well the mass of motor and transaxle.

The dogbone pendulum mount that he hasn't changed yet affects on the steering response, not so good but not so bad.

The frequency of the shaking is well involved in maintaining straightness, so she has a dull steering response, but she goes straight somehow.

It straddles the front axle weighing 200kg, so the rocking motion has a great effect on straightness.

Not only does it's damper springs improve ride comfort, but the condition of it's front engine mounts also greatly affects on rear ride quality.

Supporting a vehicle weighing more than 1 ton moving at high speed, putting a mass of 200 kg in the steering section and hung it with rubber's repulsive force as a mass balancer to dampen vibrations and noise while establishing a seismic isolation structure.--- I get a headache just by such an imaginations.

Research and development engineers must be making efforts to match the viscoelasticity and dynamic equilibrium of rubber.

Candidate Audi A3 8P-CAX got well & fine Plum flower


Periodical legal inspection by the authority was successfully done on my Audi A3 ABA 8P-CAX today at Kobe Hyogo Land Transport Branch Office. As for car battery changed into 75D23L instead of european formula, no complaint was disserned by the inspector at all. 

Due to the inspection form that was automatically issued with the necessary information filled in by the reservation code, it ended up being two sheets with a certificate stamp attached, and I was confused. A certificate stamp must be attached on the sheet according to the reservation code. It's a new matter.

The inspection certificate issued today containes small laminated IC tag, just like the previous Air-cooled Beetle a few weeks ago.   


As I could imagined the good timing for plum flowers this year, I dropped in Koto Plum Tree Garden and Nakayam Kannon, and they were both to the point, Bingo! 

Consequently, Plum flowers are over and the next is Cherry Blossom!

Minolta MD Tele-ROKKOR 200mm/f4.0 obtained


Minolta MD Tele-ROKKOR 200mm/f4.0 lens was obtained in Yahoo auction at the cheapest price, 37 yen like nothing. The formation of mold was observed on the back surface of the 3ird element, it was not invasive and the surface recovered safe resulting like new. Surfaces sandwiching a diaphragm iris blade room and external ones were cleaned thoroughly as usual. It goes without mentioning that the item performed good enough at all.

Later investigation in the website taught me that the later model named MD 200mm/f4.0 has an inevitable disadvantage, the rear module was changed into engineering plastic one piece method resulting no way to disassemble for maintenance.

On the other hand, my MD Tele-ROKKOR 200mm/f4.0 has no concept as disposable item, fully metal lens supporting method is invited.

Very good physical performance can be obtained at the lowest price if only Auto Focusing is given up even if it had been produced 50 years ago, Silver Salt Film golden period of time, my good days.

Molded and fungused camera lenses are good for geriatric to kill time with no crime.
