Thank you, both.
I am looking only for a hood since it looks like that is very much needed.
I go look for the Topcor Series 9 clamp on hood.

You are right about the UV filter. Is it normal to keep it on or do people have some experience with taking it of?
I usually do not use UV filter.

Very good lens otherwise, just not with the sun right on Smile

I`m not a big user of filters either but I left mine on for a while and looking back can see no image impairment using it. I imagine the filters were/are as good quality as the lenses themselves.I`ve also got a pack of the original filters now but have never got round to trying them out yet.

I have never seen the manual for this lens so I cannot say for sure. However for most lenses with rear filter, a filter is required as a part of the optical design. That said, I see no differences between with and without a UV filter on my m4/3.

With Zenitar 16/2.8 on m4/3, interestingly, I cannot get sharp images at any apertures with a filter in place. With no filters, the lens is nice and sharp. So I guess the lens' exit pupil is so close to the sensor plane that the effect of m4/3's thick sensor stack kicks in. Or probably I have a lemon.

Thank you. Updated. It started to look like maybe all the black 100/2.8 has infinity lock...

Okay now the known population of the 135/4 doubles in an instance. I wonder why no one has noticed any samples from the 1000-2000 range before. I actually have seen quite a few of this lens and all has serial number <1000.

Now this is an anomaly. The serial number is so early on that at first I tought it's a V3 with a V1 name ring. However upon closer look, nothing seems to be right. The real V3 has orange feet scale with only a single infinity symbol for both feet and meter. This guy has white feet scale with two infinity symbols, similar to the F-series 13.5cm. However the F distance scale doesn't have feet/meter units since the units were screened on its distinctive clear plastic windows. The all black dual rubber grip is similar to V3 but the hood is clearly from the F. Nice catch indeed Calvin.

Thanks for mention all the details. I can only notice the chrome strips on the hood which is not found on V3. Embarassed

Don't get me wrong. I do think this is an interesting discovery of a potentially very unique and collectible lens. I hope someone on this board would get the lens and report back whether it is a genuine transition product. Yes there is a chance that it could be a cleverly crafted Frankenstein but I don't think that is very likely.

My gut feeling as a collector tells me this is a genuine copy.

P.S. I have send an mail asking for a photo showing the lens mount.

Yes Topcon did aim high with the R series. The super fast 13.5cm/2 was one of the first in the series. Another notable fast lens was the Big Bertha 30cm/2.8 which was supposed to be as magnificent as its Howitzer namesake.

It's more common than the RE 85/1.8, I've been wanting it for a long while, if it's anywhere close to my 135/3.5 in performance, it will be a stellar performer.
