The company was founded in 1873, during the first decade of Japan's industrial revolution, by Rokusaburo Sugiura, who suggested that his employer, the Konishiya apothecary in Kojimachi, Tokyo, begin to sell the new cameras and photographic materials that were being imported from Europe and the United States. The apothecary owners consented and gave Sugiura permission to use the Konishiya name. This was seven years before Kodak was founded.

FUJICHROME Sensia 100 Review

All-round color slide film for every outdoor shooting situation: snapshots, landscapes, and portraits. Fine grain, brilliant and natural colors.

FUJICHROME Sensia 100 [RA] is an ISO 100 high-image- quality daylight color reversal film. Features of this film include beautiful skin tones, natural
and true-to-life color reproduction, and smooth textural depiction. Its high color-temperature tolerance during exposure makes it easily and widely applicable for slide production not only for snapshots, scenery, and other general photography, but also for medicine-, science-, and industry-related photography. Sensia 100 is ideally suitable for slide projection and for making big enlargements, as well as for printing on FUJICHROME paper and making high-quality duplicates using duplicating film.


Asahi Pentax Auto Takumar 85mm f/1.8 Lens Review

Less known lens than famous SMC Takumar and lot more rare.Very well built mechanically, real competitor of many famous lens like  Carl Zeiss Jena Pancolar 1.8/80mm or Nikkor 85mm f1.8  Perform well as short tele-photo lens. Amazingly sharp even at wide open,it has beautiful color rendering, nice bokeh. I love this lens it's draw magnificant images like a paint for story books. It has very own character.

Leica Summicron-R 50mm f2 Lens Review

Reviewed by Orio Menoni
This lens was introduced in 1979, as the final evolution of the reflex version of Summicron 50, probably the most successful Leica lens of modern times.
Compared to the first version of this lens, released in 1964, this third version features, just like the second version (introduced 1976) a completely recalculated optical scheme, and a completely different barrel design. The most important change is of course the optical redesign, which improves the performance of the lens wide open, and improves the sharpness too, perhaps (like someone says) a little at the expense of wide open bokeh. There is no optical difference between the second and third version of the lens, the latter one being compatible only with the R reflex cameras (thus not any more with Leicaflexes).

Tamron SP 300mm f/5.6 54B Lens Review

SUPERB!! I guess don't need to say more. I didn't find any weakness of this lens, color, sharpness, macro capability just excellent, if compare all this features with other 300 mm lens this is the number one. Better than Carl Zeiss Jena Sonnar 300mm f/4, Pentacon/Meyer Orestegor 300mm f/4 , Nikkor 300mm f/4.5 AI or Tair 3S.

Nikon Nikkor 85mm f2 AIS Lens Review

Small handy like an 50mm lens. Very well built professional lens like all Nikkor AIS. In my opinion ideal to use for portraits , not very sharp at wide open , but not soft at all. Excellent choice for portrait photography to make smooth skin tone.Some people has strong criticism about this lens , they said optical quality is not reach the highest level like 85mm Nikkor-H 1.8 have. I have both lens, I  don't think so this lens weaker this is an excellent lens from every point of view.If you want ultimate sharpness take Nikkor 105mm f2.5 AIS instead of this lens. Quiet large f/2 maximum aperture is  helpful in shooting indoor or in low light environment. Subtle blurring of the background for beautifully natural and evocative picture.Works perfect with any DSLR camera what can adopt Nikkor lenses and film cameras.I tested this lens with Olympus-E1 and Nikon FA.


How to clean aperture blades

This problem is hard to fix . You have to remove each blade of the diaphragm and then remove any "grease" dirt from them with "gasoline" for lighters (or "dry" solvents) and inspect the blades to see if they are not oxyded on their edges ! Then , you have to polish the blades with polishing media , then clean one more time with dry solvent and if your polishing give a too "blank" aspect , you have to "reblue" the steel with a gun blueing chemistry.

Carl Zeiss Biogon

A lens with an angle of view so wide that it can capture very much of the life around us in a single frame – this is what the name originally means.

Typical Biogon® lenses:

A focal lenght only half the diagonal of the film frame, produced with an almost symmetric lens design of surprising compactness, featuring the typical advantages of symmetrical lens designs: distortion is extremely well controlled, and so is color correction and image field flatness.  
Combined with extreme precise manufacturing these properties make for an outstanding wide angle optic with high resolution, an excellent documentation tool.
