Sumilux M 50mm f/1.4 lens + Filter = Vignette

Friends:

 

I noticed that using the Sumilux M 50mm f/1.4 lens with a BH filter gives me a vignette. (Darker on the edges of the image than in the center)

 

Is there a way to use a filter for protection and not have this problem?

 

Thanks amigos,

What's a "BH filter?"

 

I doubt it's the filter that's causing your vignetting. If you slide out the hood, you'll notice it extends far more than any filter ever would... The Summilux-M does have inherent vignetting when used wide open and doesn't completely go away until about f/2.8 even with coding.

 

Check out the vignetting test near the bottom of this review.

Perhaps a "B+W" brand filter? I notice the B+W filters I have do have an effectively thicker ring, that protrudes a bit more into the glass area than my Leitz filters.

Older B+W filters, yes. The regular B+W UV filter on my 50mm Summilux ASPH has a mount that is no more than 4mm deep beyond the thread. A Leica-branded filter is 5mm. Slim-mount filters, without the front thread which is pointless if you don't have to screw a hood into it, are even thinner.

Sorry! Its a B+W filter as suggested above.

Thanks for the education on the vignetting of this lens at wide open! You all are most kind!

As noted, wide open you will notice vignetting. In my use of the lens the vignetting has increased with lower light and with the hood extended, again at 1.4 and 2.0. It is easily rectified in post processing.

Wish I had a 50/1.4 to vignette at 1.4 and 2.0.
