Do you have duplicate lenses in same focal lenght? Why? Why not?

For me, it is curiosity before anything else. How does a Summicron render images, and how does a Biogon perform for me? Why do some people love the Pentax 43/1.9L or the Rolleiflex 40/2.8ltm? I want(ed) to know.

During your search did you find the "if I could only have one" lens?
 
Well I have a bunch of 50mm's and another on the way. Oldest M mount is a 50mm Summicron f/2 DR which I have had since the 1960's. It's used for it's great film like images on my M240. Then I have a Sonnar 50mm f/1.5 M mount thats for low light use and it's great contrast and vivid colors and finaly a new to me Chrome Summicron 50mm f/2 version 5 which will be an everday default lens for the M240. Then there is the Screw mount 50mm summicron f/2 collapsable for my IIIF and another screwmount Voightlander 50mm for the same camera. My M2 just has to share!! They all shoot a bit differently and have different strengths and weaknesses.
 
No. I am satisfied with the lenses that I own, but each lens differs slightly from the rest of the lenses. The Rollei 40/2.8 is super smooth but other lenses are faster and sharper, say.
I enjoy the act of creating images more than owning lenses. I enjoy picking out two lenses for use each weekend. I rotate around my favorites.
 
I have a bunch of 50's usually because they come with bodies I've acquired. Other times, I just like the look of one, or heard a good thing about another
here's a breakdown by mount:

Olympus OM:
Zuiko 50/1.4

Nikon F
Zeiss ZF.2 Planar 50/1.4
Nikon 50/1.4

Nikon S:
MS Optical 50/1.3
Zeiss S-Mount Sonnar-C 50/1.5
Nikon S 50/1.4 (re-issue)

Classic Contax
Zeiss Sonnar 50/1.5
Zeiss Sonnar 50/2.0

Leica:
Summicron 50/2.0
 
The only duplicates I have in some 40 lenses across 3 formats are:

2 x 35mm's for Leica, 35mm Summicron V4 and 35mm 1.4 FLE.
2 x 50mm's for Nikon, 50mm 1.8AIS and 50mm 2.0 Zeiss Milvus.

Other than those two sets, no dupes.
 
Is it for different looks, systems, speed, ...?

Just because they're your most used doesn't mean you need multiples.

I'm genuinely curious btw.


It's for the different renderings and image quality of a lens.
For Leica I have a 35mm f1.4 pre ASPH Summilux and love it's rendering, but also have a 3.5cm f3.5 Elmar for how it renders.
And 50mm f1.5 Summarit for its image quality as well as a 50mm f2.0 Summicron version V for how it renders.

As well as different systems.
For my Nikon system I have a 50mm f1.2 AI, 50mm f1.8 Series E and 55mm f3.5 Micro Nikkor.
I like the image quality of the 50mm f1.2, but it has distortion so I use the 55mm f3.5 Micro Nikkor.
And the 50mm f1.8 Series E for how compact it is.
 
I guess it was a question that implied "duplicates in the same [RF] mount"... in any case with the exception of LTM / M-mount the reason for multiples is different mounts. Edit: non RF lenses not shown

28 - Canon (S) LTM: 28 f/2.8
28 - Leica M-mount: 28 f/2.8 Elmarit-M ASPH

50 - Canon (S) LTM: 50 f/1.8
50 - Leica M-mount: 50 f/1.4 Summilux-M ASPH

I do have multiples of the same focal length but only in LTM not in M.
Many came with a camera body and some bodies were bought just for the lens.
Unfortunately I have more camera equipment than I have time to use right now and hope that will change soon.
Being a machinist I love the way the old lenses were made and also appreciate the Barnacks more than the M's I have.
 
Four 35's for my M6.

Leica 35 Summaron LTM
CV 35/2.5 LTM
Nikkor S 35/2.5 ( sharpest 35 I have )
Nikon 35/2.8 M from a 35Ti

All these lenses are pretty sharp and render color differently, but that Nikkor S is special.

No other rangefinder lenses in my kit.
 
I recently got a 50mm m-Hexanon as a second 50, after my c-sonnar which I have been using for the last 4 years.

The c-sonnar is absolutely brilliant on film, but I felt that a more regular 50 would be a better choice on my M-P.

The digital sensor is brutal on focusing errors. What looks charming on film looks sloppy on digital.


Am I among the small minority here at RFF for having multiple lenses for same or similar focal lengths as RF lenses?

I keep such duplicates because I like using them whenever it pleases me to do so. I don't actually need to have any duplicates.

What about you? Have you reduced your lens counts to reach a minimal set?

I am OK with what I am doing. I enjoy a lot to inspect and use high quality craftsmanship and superb optics.
 
Only for 50mm. I've been a longtime user of the Noctilux ASPH which is simply too heavy for day-to-day use. I've recently added the APO-summicron which is superb and lighter than any of my other M lenses.

Used to have duplicates for 35 and 50 in E-mount but didn't use them enough to keep them around.

In 1998 I was admitted to the Yale Psychiatric Institute (has since been closed down, and described as a "hell-hole" by my shrink.

I am quite certain that a brain implant was inserted during my stay there. I could feel something like a small bolt of lightning going into my brain. There was a bump on my head near the location where I thought this thing came from. This evil did something like an electric shock when I communicated with people, leading to an considerably lonely life in a garage shop/studio making violins.
 
In 2012 I used some violin making tools to stab this bump on my head. I've been told that subsequently showering and rubbing with ointment, a very fine wire worked it's way out.

After that, life improved greatly! My partner has been very much a saint and a savior to me, if I could just figure who was the real one! They keep rotating them (clones?) in and out of my house and life for no fathomable reason.
 
This can't go on!!!

Bring them all here at once and we'll see if we can work out what's really going on.

Or send me to a deserted island to make violins on my own improvising my own compositions on them (I can be quite self-sufficient).

Or kill me quickly and painlessly.
