This is a follow up image to a question George Lottermoser had  
comparing the Leica and the B+W UV/IR filter.

This image is nothing special except it was taken in my backyard with  
a very clear, blue sky. I just received the 49mm leica filter from  
B&H to put in my Milich adapter for the WA Tri-Elmar. The adapter  
allows use of the original, very small lens hood that comes with the  
WATE. I had been using the poor 67mm filter holder that Leica sells  
for this lens.

The lens, M8 with lens detection plus IR set on was set to 16mm. The  
photo was taken with the lens set wide open at f4. My eyes tell me  
there is absolutely no cyan creep. The Leica firmware matches the  
filter just fine.

I have run the same test in the past using the B+W filter which shows  
cyan creep due to the firmware under correction of the stronger  
filter and with the Tiffen filter that shows a beige creep due to the  
firmware over correction due to the weaker Tiffen filter.

I hope this helps to answer some of the questions that have been  
asked about the different UV/IR filters.
