Soligor 35 mm f/3.5 KA on eBay

[Stefano]

A bit expensive compared to how much I paid for mine, but looks good and the rear element looks to be the "high UV transmission" type.

By the same seller, possibly also UV-capable, even though without the Prinz-monicker: https://www.ebay.co.uk/itm/254554051014?hash=item3b449a91c6:g:1~8AAOSwhLhef75k ?

The rear element seems to be a good one, but I don't know if this is enough. I still think this second lens probably does reach deep.

Yes, all 35mm lenses with a rear element and mounting ring looking like that, that I measured, has had a good UV-performance.

A long time ago I posted about that. Possibly during 2017.

Is this an example of a bad one? https://www.googleadservices.com/pagead/aclk?sa=L&ai=DChcSEwjE6_Hk0OjwAhVDo7IKHQziDEMYABAGGgJscg&ohost=www.google.com&cid=CAESQeD2fI9q2tqamgSskWBT3TmTn5T04DMfu8UL4qdAyWp75a7Qvp5S28uSAFaXgGmbaVZS6EfJDfDafDDRtyHDvCch&sig=AOD64_3KVhXM3CUvpjW96TaFwTrxdG7MDw&ctype=5&q=&ved=2ahUKEwj-p-nk0OjwAhVsk4sKHcBtAcMQwg96BAgBEA8&adurl=

 

I think counterexamples can help people identify good ones better.

I have no idea as I have never measured a lens looking like that.

Beside from that this lens is junk with a broken aperture mechanism, it reminds me of a PRINZGALAXY-lens that Jonathan measured as a very good performer.

His lens has such a wide flat surface at the front just inside the filter threads, but there is also a risk that it could have a bad UV transmission as it is not an exact match.
