Hello, everyone!

Very nice, the bokeh isn't too fussy and the lens looks plenty sharp. Cosinon made a lot of lenses for other brands, I wonder if this lens turns up with other names?

My sample is identical to the Revuenon 55 1.4 (except the finishing of the focus ring) . Everybody says that the Revuenon is a Tomioka because of the flat rear element. It could be that it is actually made by Cosinon.
This Cisinon generates unfortunately a lot of ghosting with the A7.

These flat bottom lenses were made by two manufacturers - Tomioka and Cosina. They have similar biotar design but they are different. They have different construction. Tomioka made lenses have easily unscrewing first element, together with filter mount. Cosina have three screws under their front round plate with lens name. The first elements are different, but you can tell that only if you hold them one by one and see them together simultaneously.

BOTH lenses can be named Rikenon 55/1.4, Auto Revuenon 55/1.4, Exida 55/1.4, Exactar 55/1.4, Sears 55/1.4, Mamiya/Sekor 55/1.4, Porst Color Auto Reflex 55/1.4, Super Carenar 55/1.4, Super Reflecta 55/1.4. To differentiate one from another - try to unscrew the first element.

As I know (this maybe not true) Cosinon version is sharper wide open, but needs a hood (I use it with a hood), Tomioka is less sharp but more flare proof.

Cosinon 55/1.4 is a great lens, I just LOVE it. Great for portraits, flowers, city photos...

It looks like the Revuenon has the same three screws. I saw it on a picture of this lens.
There was a thread about the Revuenon from Ikaren on this site where I posted pictures of my Cosinon which show the similarity of those two lenses'in every detail.
This Cosinon is a vey nice lens with my micro 4/3 camera but has unfortunately too many ghosting and flare problems with the A7 sensor.

Wonderful results. Adding to my list.

I would like to ask what a fair price is for this? and what I would look for on ebay to find it? Want to make sure it's the correct copy etc.

This is flat rear Tomioka sold under many names. I don't know any other 100% flat rear 1.4/55mm lens, so this is your distinguishing characteristic.

Even better, i must try to obtain such results myself Smile.

hmm, should I be able to tell this via a picture on ebay? I think I would need a side by side to tell the difference fist... :9(

As I said, flat bottomed lenses were made by BOTH - Tomioka and Cosina. All Cosinon lenses are manufactured by Cosina with no exception. So there are NO such things as Cosinon 55/1.4 made by Tomioka, despite sometimes you can see this on ebay. Cosina and Tomioka 55/1.4 designs are close relatives but they are not the same! And they both have flat bottom lenses.

I already told how you can determine one from another (if you can unscrew the front element easily without a screwdriver - it's Tomioka design, if screwdriver is needed - it's Cosina design).

Who is manufacturing the Chinon 55/1.4 (with flat rear element)?

Very nice pictures in this thread!

I had this lens as both Rikenon and Cosinon, and they where equal so I kept only the Cosinon Wink

Eh, sorry to be out of topic but what is that camera and lens in your icon pic? My gosh!

Back to Cosinon 1.4, I bought it recently, it is my first manual lens. I LOVE IT. I never had a 1.4 before, the color rendition is mind blowing, very vintage looking for portraits. But I adore it for macro. I took several pics yesterday using a extention tube with it.

Here you go.
Yes it is a fine lens indeed
OH

What is really good for us is that it's not only a good lens, but it was manufactured for several decades and it's really easy to find one.

This is brave and also very interesting and revolutionary statement. Especially: "All Cosinon lenses are manufactured by Cosina with no exception." This is new to our discussions and could truly help understand and sort few things out if confirmed.

Could you shortly explain your views (findings) on:
M42 Revuenon / CHINON / Tomioka 1.4/55mm model (leather grip)
M42 Rikenon 1.4/55mm (two models: 100% flat rear and slightly convex)
M42 MC Revuenon / CHINON 1.4/55mm model (smooth focusing line)

I don't understand why you're being so sarcastic. What caused that, I wonder?

Cosinon 55/1.4 is a lens designed and manufactured by Cosina and Cosina only.
Tominon 55/1.4 is a lens designed and manufactured by Tomioka and Tomioka only.

Many other brands bought one of these lenses for themselves. Many of those brands bought BOTH of those lenses in different periods of time. As I said one of these lenses can be named Rikenon 55/1.4, Auto Revuenon 55/1.4, Exida 55/1.4, Exactar 55/1.4, Sears 55/1.4, Mamiya/Sekor 55/1.4, Porst Color Auto Reflex 55/1.4, Super Carenar 55/1.4, Super Reflecta 55/1.4. I forgot to name Chinon and perhaps some more brands, as they were truly numerous at that time.

I told how those lenses can be differentiated one from another.

As for your statements taken probably from ebay, they are not a thing to be looking at.
There cannot be such thing as M42 Revuenon / CHINON / Tomioka 1.4/55mm as Revuenon is a trademark of german Foto-Quelle of Nuremberg, CHINON is a trademark of japanese Chinon Industries inc. Perhaps someone wanted to say that the lens he is selling is designed by Tomioka and it is similar to Chinon and Revuenon lenses, or something like that.

Personnaly , I stopped taking seriously this story about Tomioka or not Tomioka. It is typically the internet topic.
I own a Cosinon 55 1.4 and I could see a Revuenon which is externaly identical ( except the focusing ring).
I have not used my Cosinon with my A7 because of the flare and ghosting problems which I mentioned.
It is not a versatile lens or perhaps I had a bad adapter.
Seeing some nice results , I shall give it another chance.

About Chinon , there are some Chinon 55 1.4 with Tomioka written on it.

I must give quick response: believe it or not, i was fully honest, no sarcasm intended. Now i will read your reply in detail.
