Problem with IR/UV filter and 24mm Asph Elmarit

I finally took the plunge and joined the Leica M8 revolution. This began a chain of events that continues today. Of course I also needed a few new bags, an extra battery, more SD cards, SD card storage device, portable hard drive, new computer software, new iMac to go with new software, new table in study to hold upgraded computer, higher chair since my neck hurts now when viewing the larger screen, country AC adapters for travel and a cart full of UV/IR filters. Wow - what a transition. Now the problem.

 

I am can't seem to attach the Leica lens shade on my 24mm asph elmarit with the B&W UV/IR filter screwed into the front of the lens. Do the filters come with thinner profiles? Or perhaps I'm just not pushing hard enough...

 

Any suggestions?

Hi Richard,

 

it's a tight fit, but it should work - at least it does on mine.

 

Best regards

Yeah some of the B+W filters are big and you can't get the hood on Leica lenses when using them. I suggest you get a 55mm (E55) Leica UVa/IR cut filter. They are made to work with the hood.

I believe the slim filters work best with the hoods. The slim filters have no threads on the front to receive other attachments.

Richard, I don't have a 55mm Leica UV/IR filter yet but I can tell you that with my 24mm I can't get the lenshood to fit properly with either Hoya or B&W filters but it does fit with the Leica UVa. My 39mm and 46mm Leica UV/IR filters look to be identical to their UVa equivalents, so I'm living in hope the the Leica 55mm will work.

Richard:

 

Don't fully tighten the filter and the lens hood should fit on better. Once on, tighten the filter.

 

I have the B+W 486 F-Pro and although a tight fit, it fits on my 24mm and I can get the hood on.

I got it!! You need to push on the top of the shade and then the bottom. Finally it clicked into place. I'll leave the shade on at this point. I don't want to push my luck.

and I believe that the "slim" filters are slim in length, but actually thicker in diameter to make up for the loss of strength lengthwise....at least I read that somewhere

I bought the slim B&W filter for my 24/2.8-asph, and while the hood can be squeezed into a position where it seems to be pretty firmly set, it is certainly not clicked into the grooves on the side and the orienting notch on the top. Is the Leica filter smaller in diameter so that the hood can slide back over it?

The problem with some filters not fitting the 21mm and 24mm ASPH hoods is in outside diameter of the filter ring, not the length of the filter ring. All the Leica filters and the B+W filters from a few years back will fit. I think the Hoya will as well, since I used Hoya 55mm filters for black and white work with these lenses. The new B+W f-pro filters also fit fine in the hoods.

 

If the filter fits, the hood will click into its normal stops.

I filed down the lugs on the inside of the hood a bit.

I have them on my 21-ASPH and the 24-ASPH (both lenses have identical front pieces and use the same hood). It's a tight squeeze but if you go gently and play the hood a bit it will eventually slip over. Make sure you keep those spring buttons pushed in whilst attaching the hood.

Richard, I had the same problem initially and stumbled on the solution proposed by Robert.

 

I have since replaced the clip-on hood with one of the Chinese-made round metal hoods. I leave this on and have retired the Leica square hood. I have not purchased lens caps for the round hoods, instead putting them away carefully.

 

Since there is no cap in place any longer, I find that my first exposure no longer always takes the second noise-removal dark exposure. That is to say, my first exposure no longer has the cap in the way.

Having gone through this problem myself, I can tell you that the regular B+W or F-Pro will fit. The slim versions will screw on but they are slightly wider than the F-Pro and cannot accomodate the plastic lens shade. Hence the inability to fit the lens shade over the lens... With an M8, you are still fine with the F-Pro mount as the effective focal length is about 31mm. The minimum is 28 mm at which point vignetting becomes significant.

Looking ahead, when Leica brings out a FF M(9) then they will have to develop a slim filter that fits !!!!!

I have done the same bought metal round hoods and put the Leica's away. Like them so much better too. Even bought a 39mm for the 90 macro, but i have them on the 35 lux , 28 cron and did have them on the 21 and 24 also. E-bay like 9 dollars each
