Asahi Lens shade?

[Nesster]

I know this should go into another section, but I figure folks here will know:
which Takumar did this go with?

It's 49mm thread, and I figure for something before the Super Tak.

I paid $2 for it at a camera show.

Hard to say, when so many Takumar lenses were 49mm. It looks like a shade for a normal lens.

Nesster,

I have one that the black ring is 46mm and came with my preset tak 135mm. It also fits my 35mm auto-tak. I also have a silver and black one like yours that has the silver part 49mm black hood portion is between 52mm and 55mm filter ring threads. The treads on the hoods are the same and are not the size of any filter thread I know of.

These are generally from the pre-Spotmatic era, i.e. taks, auto-taks and early super-taks that were labeled as auto-taks.

I also have another one somewhere that the silver ring has glass in it. UV I suppose.

Edit: I guess I should take a pic of them sometime.

By it's shape and it's 49mm thread, it would work very well on a 50mm lens.

Nesster, from what I've found, most of the early Taks (those prior to the lenses labeled Super Tak) were 46mm filter threads. The only thing I've found with 49mm filter threads were the M37 Asahi Kogaku Takumar in 83mm/1.9 and the M42 Takumar 83mm/1.9. Everything else below this focal length took 46mm filter with the exception of some that took much larger. With the silver color at the base, I would think it came from this era and most likely one of these two lenses.

hard to say. as already mentioned, nearly everything prior to the Super-Takumar series within the wide-normal-short telephoto range had a 46mm threads. this hood looks a bit too wide for a short telephoto and it certainly looks to date from somewhere between the Takumar through the Auto-Takumar series due to the font used in the company name and the two tone finish. but oddly enough.... the only "normal" lens with 49mm threads would be the all black Auto "Super" Takumar 55/1.8.

I have three of these earlier style two piece hoods (all 46mm) for my Auto-Takumar 55/2 and 35/3.5's and one hood for the Takumar 58/2.4 (which I don't own) and I can honestly say, that I have never seen one with 49mm threads. the hood from your photo looks about the same as the hood for my 55/2, so I am leaning towards the 55/1.8. sadly... this is another case of "I wish I owned the ultimate screw-mount guide."

here is a list of possible candidates:

Takumar 83/1.9
Auto"Super"-Takumar 55/1.8
Auto-Takumar 105/2.8
Auto-Takumar 135/3.5

Seamuis' list is accurate. I have the auto-tak that was actually an early Super labeled as an auto.

I checked and I do have a silver ring with glass in it and fits 49mm filter threads.

The 200mm f5.6 Tele Tak also had 49mm threads.

[Nesster]

Thanks for the info - I have that auto tak 55/1.8 as well... this definitely isn't for the 200, as I have that lens with the shade it came with.

Blue - is the silver ring with glass an Asahi, or is it perhaps a series (VI? VII?) adapter + filter + shade set?

I don't suppose you have the case that came with it? I just checked the bay, and there is a copy of this exact hood and it has the older style brown leather case (like my three 46mm hoods) the brown leather was used with the first few Pentax models during the 50's. by the time of the SV they had switched to a 'grained' black leather. so it certainly has to be 50's. it could still very well be for the Auto-"Super" Takumar 55, but just to give it a rough date I would say late 50's. my guess for its focal length fit is simply because it isn't labeled for a specific lens, this usually signals a 'normal' lens. the hood for my 55/2 does not have ant markings other than 'ASAHI OPT Co. Japan' same goes for the hood for the 58/2.4, while the hood for my 35 is marked 'Takumar 1:3.5 35mm'.

Yes I see the ebay item:
"DESCRIPTION: - Lens hood for very early Pentax cameras. Has Asahi OPT Co. Japan engraved on the chrome ring. This is for series filters and is a 49mm screw-in. Has the original Asahi Optical case marked "AOC". Hood has light signs of use. Case is really nice."

Interesting, I haven't looked at whether the shade and mount can be separated.

Mine was $2 and did not come with a case... though perhaps the case is somewhere in the box, for another $2

Nesster, the bottom ring is like the one on your shade. There is a piece of glass sandwiched between it and another ring. They look like they should come apart and allow the glass to fall out. However, they may be glued. It came with an H3 & auto-tak 55mm f1.8 (super tak type) lens but who knows how it came to be with that lens. The set that I have that is like yours came with a regular auto-tak 55mm f1.8.

If yours is like mine, both the 49mm ring and 46mm ring allow the hood to screw off but the threads on the shade are between 52mm & 55mm.

I realize I don't have a good pic of the Series filter/shade setups I have - I'll rectify this ASAP

In the 50s into the 60s, and probably before, one of the main filter systems was the Series. This consisted of a bunch of adapters - push on, screw in, bayonet - for various cameras. The other end of the adapter was the filter holder, in standard sizes - Series IV, V, VI, VII and so on - the larger the numeral the larger the filter. Then you needed either a keeper or a shade that screwed into the adapter, sandwiching the filter in between. The filter itself usually was just a bare round piece of glass or similar material.

In an era before filter thread standardization, this system made sense. The alternative was to produce camera specific filters - of which there are plenty of examples.

its not 52mm, im fairly certain. it has to be slightly larger than that.

Nice find. It will fit:

83mm f/1.9 PRESET
55mm f/1.8 Auto-Takumar (NOT the 1958 Zebra)
105mm f/2.8 Auto Takumar
135mm f/3.5 Auto Takumar

Based on size... ie: depth... I've always took that hood to be for the 55mm f/1.8 Auto-Takumar The version in question is actually the very first Super-Takumar. In other words it was called an Auto Takumar, but in function it was a Super Takumar. These were introduced in 1960. If you are not aware of this page, it is helpful in finding this kind of information Early Pentax Takumar Lenses.

I have one myself. It's in excellent user condition. $15.00 I use it on my F 50 f/1.7 auto-focus all the time.

Kind regards,

Seaain
