Supposedly, the Rokkor 40/2 was multicoated whereas the Summicron C was single coated.

Thanks! Not so far east as to be closer going westward! I got my lens from a Canadian RFF member who got it somehow from Japan.

The rearmost glass surface is well-recessed into the mount, as the SLR glass is remounted in an LTM barrel (rumored to have been supplied by Cosina), which needs the extra length at the rear to make up for the thinner Leica body vs the Pentax SLR.

The lens diagram resembles many other Pentax lenses in the mid-range focal lengths including 85mm as well as the Zeiss Planar ZK.

Thus explaining the length of the 43/1.9 LTM, it is about the same size as the Konica Hexanon 50/2 in M mount, perhaps even a tad longer.

Hacker,

This looks like it's in pristine condition!! The black and red theme across the lens, camera, case and strap is so matching!

Anymore pictures for this rarity?

Cheers,

I got inspired by Kim and folks here and a very kind member here sourced and worked out the logistics of sending the lens from Japan to me.

Found these on a hard drive (knew they were somewhere). A few shots for a size comparison.

Hi Raid

Very nice photos, thanks for sharing.

With the exception of the 3rd and 4th below, which are very sharp, it appears that there might have been some off focus, or off-scanning done in your samples, as they are just not as sharp as examples 3 and 4.

I've found that focusing wide open can vary even when different LTM to M adapters are used (if at all) on an LTM lens so maybe that is a factor as well.

very nice photos! It is a long lens, but it's the only 43 < f2 for rangefinders, I think. Built in lets it fit in the same compartments as the smaller CV's and Rokkors with their hoods on.

The barrel space in the back is deep, no deeper than the 75/1.4 lux though. Has a very nice balance to it, but it is about twice as long as a small Cron or Rokkor.

This is a bit off-topic but has anybody used the 43mm limited on an older manual Pentax body? I'm curious about using this very compact lens with a Pentax MX. How is the focussing action?

Thanks.

Yeah, I used it on an LX for about a year. Very compact, great images, but the focus ring is quite thin. And since it's an autofocus lens, the action is a little bit granular. But I liked it.

i've used the FA43 on an MX and ME super before. it is a rather small combination. the issue i had is that with the older bodies, the camera rests on the aperture ring when you put it down. the aperture ring scrapes any surface that you place them on. for old cheap M lenses, this is no worry but for the FA Limiteds, i took very good care of them when i had them.

although the focus ring isn't that great, the focus ring throw is actually very generous for an AF lens. if you compare the focus markings to the similar 40mm Ultron, you'll see that the focus scale is pretty similar.

This thread reminds me to use the 43mm/1.9 LTM. It is an awesome lens after all.

I placed the Pentax on the Bessa R a few minutes ago. The size of the lens is larger than what I am used to with 40-50mm RF lenses. The finder gives the 43mm/50mm lines. Here are some pics of the set:

Hi Raid,

Looks very nice. I've only taken mine out a couple of times, but haven't needed any external hoods, just the small built-in one. Have you found the need for extra hood?

I forgot that the lens has a built-in lens hood. The extra lens hood provides extra protection for the front glass.

Abbazz,
I notice the unusual serial number of "your lens", starting with the digits 12. The other lenses shown here start with 0000.
Do you know why your lens has the large number?

I wonder if they did that just for the silver versions?

Could be, so that 12 implies chrome,and the last 4 digits give the serial number.
I looked up older threads with same chrome lenses starting with digits 12.

800 lenses were made in chrome and 1200 were made in black.
You would think that using 12 is better suited for the black lenses.

Raid, I think you're right about the serial number indicating finish color, likely different production runs. Similarly, Bronica changed the two leading digits of the RF645 from 00 to 11 to indicate earlier production with 135mm lens framelines and later production with 100mm framelines. My black 43mm L starts with 0000 and is in the 300s.

In the end, it is the "lovely lens" that really matters. I have the 43mm lens now mounted on the Bessa R for a great set. The focus is super easy snapping in place,and the lens is soooo smooth!

Pentax's specification for the LTM version, taken from the Japanese-language promotional sheet for the lens, dated 9/2000, is 230g. (For completeness: the finder is specified as 35g.)
