Adapter For Leica E39 39mm Filter to Summitar 50mm f/2.0 Lens SNHOO Adapter Ring

I have been looking for a filter adapter to E39 for my 1950 90mm f4 Elmar LTM and found the above adapter available on eBay for the Summitar. Looking at the photo on the listing the thread size looks similar to what is on my Elmar. I have been in touch with the seller but he cannot confirm the thread size compatibility. Can anyone tell me if this adapter might work on my lens? I would prefer to use a thread in adapter rather than a clamp on due to the size and weight of my lens shade.

No, that won't work. The Summitar has a unique conical thread. The SNHOO (and its modern copies) don't fit any other lens.

You can use a clamp-on SOOGZ adapter for lenses (like most Elmars) with an outer diameter of 36mm (A36) and you can also find A36 clamp-on hoods, such as the FIKUS variable length hood.

The filter thread of the Elmar is I think 34mm (E34) with a 0.5mm thread pitch (measure yours to check - some Elmars have E39 threads, but I think they are later than yours). 34mm is pretty uncommon, but you can find a limited selection of modern filters and hoods in this size as well as stepping rings. One of these rings may be what you want if you already have an E39 hood and prefer not to use clamp-on accessories.

That adapter looks identical to the Summitar to 39mm I have down to exactly the same style of lettering and it should fit the tapered thread of your Summitar. I think mine was branded as 'Heavistar' or something but there's not problem with it. I sprayed the inside of mine matt black leaving the filter thread clear. I also have a Leica adapter that does the same thing but that comes with a blanking ring that needs to be unscrewed so a 39mm filter can be used.

The OP has an Elmar 90/4, not a Summitar. These modern rings are fine on the Summitar (I have one) though being (presumably) aluminium alloy they may be more likely to bind than the brass SNHOO.

My apologies I read the title as being the question.

Thank you very much! 
 

No Summitar used recently but if you are interested in IR there are a couple of ways to do it. I don’t like full-on IR because all I’m trying to do is lighten all the ‘greens’ at this time of year. So I try to keep it subtle and for this you can use IR sensitive film like Adox HR-50 where you can just use an orange or red filter and get a subtle effect, or  go all the way and use Rollei Infrared film and an IR filter if you like black skies and white trees. But both are regular B&W films if you don’t use a filter with them. But the really easy way to do IR is with a converted digital camera.

I very much like the more subdued look of IR that you have captured. I have shot both B&W and color with film but enjoyed the use of an old Canon D40 that I removed the cover filter and used various IR filters with it. In most cases I prefer to go the less is more approach.

I used to use the Adox films back in the 1970's and liked them veru much. I have not tried the HR-50. I will give it a try soon!

Keep up the good work... I enjoyed browsing!

Many thanks,

Keith

The adapter you linked to looks like the correct one. I did not think of looking to B&H for this. Thanks you!
