George Stoichev Posted January 9, 2022 Share #1  Posted January 9, 2022 Advertisement (gone after registration) Hi, I have purchased Summicron M 50mm ASPH brand new. It is with built-in hood.I bought also UV clear filter just for protection of the lens. Unfortunately on some of my latest shots I can see some flares. Any suggestions how to avoid it? I insist on the UV filter, do I have to buy hood for 35mm? I’m surprised that Leica didn’t invent the lens smart enough to work with the filter correctly, meaning w/out need of additional hood.

spydrxx Posted January 9, 2022 Share #2 Â Posted January 9, 2022 Filters always add the potential for flare. There are multicoated filters which are said to reduce it, but adding an additional glass surface, in my experience, invites flair. If using a filter, I'd always suggest a lens hood. 2 Link to post Share on other sites More sharing options...
Danner Posted January 9, 2022 Share #3 Â Posted January 9, 2022 Filter surface are flat and parallel to one-another. Â It's worse when used with with lenses that have flat or neatly flat front elements. 1 Link to post Share on other sites More sharing options...
lct Posted January 9, 2022 Share #4 Â Posted January 9, 2022 +1. Sans hood, the filter behaves like a front element being protected by no shade at all. 1 Link to post Share on other sites More sharing options...
George Stoichev Posted January 10, 2022 Author Share #5 Â Posted January 10, 2022 There are no hoods for Summicron M 50mm.What hood should I use and can I insert it when the filter is mounted. Link to post Share on other sites More sharing options...

If your Summicron is a 50/2 apo or a 50/2 v5 it has a built-in hood which should be extended if you use a filter. It is rather vestigial but should suffice in most circumstances. Otherwise, you may wish to screw a 39mm aftermarket lens hood into your filter or to remove the later when you don't need it. Link to post Share on other sites More sharing options...

a.noctilux Posted January 10, 2022 Share #8  Posted January 10, 2022 (edited) On my Summicron 50mm lenses, I don't use UV filter, for me not needing to add on a good lens a piece of glass which only degrades the lens performance (from my experience). To protect the lens, I use vented hood when I need, I have in many sizes as screw-in (E39, E40.5, E46,etc.) like this one, vented hood to see through (link)  as here E43 on Summilux 50 Welcome, dear visitor!

I use the UV filter in order to protect the lens from dust and eventually splashes. is it possible to use this hood with the UV filter? Link to post Share on other sites More sharing options...
lct Posted January 10, 2022 Share #10 Â Posted January 10, 2022 As i tried to explain above you just have to screw the hood into your filter. 1 Link to post Share on other sites More sharing options...
TomB_tx Posted January 10, 2022 Share #11 Â Posted January 10, 2022 the Summicron (as with many lenses) can produce a "central veiling flare" with bright light sources just outside the frame. I find the Zeiss Planar ZM much better in this regard, but overall still prefer the Summicron - I just avoid the conditions that cause the flare. Filters tend to produce reflections that are more defined than the veiling flare - like ghost images of bright spots in the frame. 1 Link to post Share on other sites More sharing options...

You thing that wven with additional hood in same condition because of the filter I’ll got flare? Link to post Share on other sites More sharing options...
BradS Posted January 10, 2022 Share #13 Â Posted January 10, 2022 (edited) I too was shocked by the current 50mm Summicron's poor flare performance. After 40 years using Pentax and Nikon I just couldn't believe that a modern lens that cost more than $2500 would flare the way it does. All of my old (50+ years) screw mount Pentax lenses perform better. I returned the Summicron and stayed with the Zeiss Planar ZM. All of my lenses get a new B+W UV filter the moment they come out of the box and I've never needed a lens hood.

spydrxx Posted January 10, 2022 Share #14 Â Posted January 10, 2022 Hood or no hood, that is the question. Aftermarket ones are dirt cheap...just get one and see if it solves your issue, almost nothing lost if you don't like it. Link to post Share on other sites More sharing options...
lct Posted January 10, 2022 Share #15 Â Posted January 10, 2022 Don't worry. The central veiling flare (CVF) is a flare you may never meet in your practice. In 30+ years i did not notice it more than a dozen times. A more common flare occurs when strong light sources are just outside the frame. Easy to avoid by placing the sun clearly outside (or inside) the frame lines of your camera. Otherwise the Summicron 50/2 v5 is not a flare prone lens that much.

I bought an H1a with 55mm f2 in 1965, and while doing very large prints my Leica-using friend commented on the sharpness and clarity. He was also very impressed with the mechanics of that lens. They were very well made. Link to post Share on other sites More sharing options...

lct Posted January 11, 2022 Share #20 Â Posted January 11, 2022 The sun was just outside the frame in your pics above i suspect. Une a good hood and maintain the sun well outside the frame and all should be fine but removing the filter when it is not needed could help too.
