Rollei 40mm f2.8 Sonnar HFT; different hoods supplied originally for Black v's Silver-Chrome lenses?

Hope someone here will be able to answer what I assumed (mistakenly) should be a simple matter to discover using a straightforward 'google' on the www.

I have an example of this lens (which I absolutely love to use) in S-Chr finish and it came with a screw-on (as opposed to screw-in) lenshood of rather dinky proportions. My understanding is that the HFT coating on these lenses is considered to be very efficient but I have some doubt about its efficacy in controlling flare when a filter is fitted - and I use filters all the time.

Here is a snap of the pairing with filter fitted to show how close is the front surface of the glass to the front-edge of the 'standard' hood;

Correct me if I'm wrong but it is my belief that a second - and rather different - style of hood was available for this lens; namely the Rollei 22123. Quote from the source and a pic from the page where it was illustrated;

"Slip-on lens hood (Cat. No. 22123), specially matched to the angular field of the 40mm f/2.8 Sonnar lens."

 

So; first of all am I correct in thinking that the latter is a 22123 hood? Secondly was this hood made available as an optional extra during the very short production run of the Rollei 35 RF? Thirdly is it a slip-on hood??? The outside surface of the lens is threaded (as mentioned earlier) so how does this hood attach?

If it wasn't avaliable as an optional extra was it only available when bought as part of the Black-Paint 40mm f2.8 Sonnar package? I've seen many photographs of the S-Chr / tiny hood but never a pic of this hood on a S-Chr lens.

Whilst production numbers of the S-Chr version are low enough at 380 examples the figures for the B-P are tiny; a mere 50 having been made (according to Rollei sources). If the hood was avalable after-market then I might carry on my search for one as, clearly, it will offer more flare-protection than the wee one. If, however, it was only available when included with the B-P lenses then I will quit the search right now!

Thanking anyone who might be able to shed some light on this matter!

Philip.

Update...

I've now seen - offered for sale - a B-Paint example complete with (presumably?) all 'bits' in original box and this lens had a B-P (B-Chr?) hood of the 'dinky' variety so was that the Normal state of affairs and, if so, was the 22123 simply available an optional extra? They don't seem to be particuarly commonplace!

I believe from memory that the Rollei hood is a rebranded CV one. I had one on a silver CV 28 f3.5 LTM chrome lens that I foolishly sold. It had a similar chrome “ring” as a vestigial hood that was next to useless. I think I still have it knocking around somewhere…

If it’s the right one it attaches with a small knob that tightens the internal band. 
 

Edit - it’s the LH-2 ?

Ah!

Thanks for the reply Nigel. I believe you are correct. It would make sense that Rollei used the CV set-up to manufacture the hood for what was in effect a reworked and rebranded Voigtlander Bessa.

A while ago I did have a look at the current Voigtlander range as I had seen something which looked a likely suspect - the LH-12 - but that hood attaches to the lens in a bayonet-fashion so I knew it couldn't have been that one.

The weather being what it is in London this time of year the aquisition of such a hood isn't exactly high-up on my list of things to do so I'll keep on 'watching this space'. Who knows? Perhaps I should simply 'Embrace the Flare' when shooting contre-jour?......😸......

Thanks again!

Philip.

If you were to find a hood, any hood, that had a "set-screw" to secure, that could work. As long as the hood fitted (snugly) over the front ring, and the set-screw had a "band/ring" on the inside to soften the screw (so it doesn't chew the lens) you'd be laughing. A half-decent machinist (def not me) could spin one up even. I think I have a Leica fitting that does similar, I use a generic 39mm hood on my old Model 1a. I'll dig it out and shoot you a pic if you need.

Thanks for the kind offer of posting a pic, gbealnz, but that won't be neccessary; as it happens I do have a similar hood to your generic 39mm so have tried that option but with a filter screwed into the lens and a hood screwed into the filter there was some resultant vignetting so I thought about going down the 'correct' route instead.

As far as externally-fitting hoods with a cinch-clip; I have a couple of 1950's Canon hoods which were intended to be used with the 50mm f1.8 Serenar and one of those (I'm sure) has such a fitting. As the lens has a 40mm filter-thread this might work. I'll have a look when I get a moment.

Thanks again for the suggestions.

Philip.

No worries Philip, and yes, now you mention it the Canons (and my Olympus Pen) lenses had such a set-screw attachment. Even if the fitting was a tad larger, a simple ring might be enough to take up the space perhaps. DIY is my middle name, sometimes it is what is needed, for me anyway. Good luck.

Is the voigtlander hood still on sale?

[Ecar]

Yes, the LH-2 works. I also use the tiny hood (more of a thread cover actually...) that came with my lens, but I remember trying the LH-2 on the Rollei. What I can't remember is if I tried with or without filter - and if using one would cause vignetting. I may be able to have a go tomorrow if anyone's interested.

The hood is discontinued, but can be found on eBay. A very nice item, although it doesn't have a cover. I bought a few of these over the years, as they are rather useful across a variety of vintage lenses.

[NigelG]

Still trying to find one I squirrelled away somewhere in its eau de nil box.
I think it’s long discontinued but as @Ecar says will fit multiple lenses as there is a little play in the fitment.

Thank you, yes, we will wait for your test shots.

I should be able to quickly test for vignetting tomorrow.

Just a little bit more on the possible use of a Canon cinch-clip hood with the 40mm f2.8 Rollei Sonnar...

Spurred on by a different thread I've had a try-out and here is one possible solution to using a more efficient hood with the 40mm Rollei.

The hood was originally intended to be used with the 35mm f2.8 or 50mm f1.8 'Serenar'-style LTM lenses from the 1950's. It is composed of two parts; the silver part features a cinch-clip for attaching the unit to the lens and the black part has a 42mm thread and screws into the silver bit. I believe the idea is that Series VI filters are sandwiched between the two parts. I'll check in a wee while...

There is no vignetting / cut-off when using this hood.

The snaps shown below were simply taken hand-held and purely to establish whether there would be any issues at any aperture. As such the first was shot wide-open and the second at f16.0. I did take a few in-betweenies in case there WERE problems towards either end of the Ap. range but, as can be seen, they turned out to be superfluous.

There IS some obvious fall-off; partly due to the nature of the lens and partly due to the available light(!) but I'm sure you will all be able to read between the lines...

A call got cancelled, so I had a bit of time to follow-up on this. Sorry for the poor phone shot, but my product photography skills are nowhere near Philip's, so I might as well make it easy for me😅. Here's the lens with a Leica E39 UV filter and the LH-2 hood. I won't be posting pictures of my office's white walls, but I didn't see any vignetting, just the usual slight (and expected) fall-off, as mentioned by Philip.
