rick123 Posted October 15, 2006 Share #1 Posted October 15, 2006 Advertisement (gone after registration) Hi everyone, My Summilux-M 50mm f/1.4 seems to allow me to use either my UVa filter (which I use for lens protection) or the lens hood. Is there a way to use both? If not, which would you use with the M6 or upcoming M8? Many thanks! Link to post Share on other sites More sharing options...

If you are going to do filters for digital, be sure to get those newer generation multi coated (both sides) versions. They at least cut flare while doing their evil to your image.

You could use a filter and a screw in lens hood. I do that when I use a step up ring 39mm>49mm and even use empty filter rings as a minimal lens shade, that will take a normal lens cap.

ho_co Posted October 16, 2006 Share #6 Posted October 16, 2006 Rick-- There were several versions of the 50/1.4 M before the aspheric one, so I may be off base here. As I recall, my Leica brand E43 UVa fits and allows use of the hood as well. I say "as I recall," because I'm a person who has a filter for every lens but uses it only when necessary. In his Leica Lens Compendium, by the way, E Puts says both sides are right in the always/never use a filter debate. --HC Link to post Share on other sites More sharing options...

marknorton Posted October 16, 2006 Share #8 Posted October 16, 2006 I only use filters when there's a chance of sea-spray... otherwise I rely on a hood to protect the lens. Link to post Share on other sites More sharing options...
rob_x2004 Posted October 16, 2006 Share #9 Posted October 16, 2006 Anyone got anything that shows a half decent filter makes any difference at all? Or are we talking about flare? Link to post Share on other sites More sharing options...
bradreiman Posted October 16, 2006 Share #10 Posted October 16, 2006 rob-i have a leica uv filter for my noctilux which i consider a very high quality filter but at night with lots of city lights i seem to get reflections from the filter. sort of off center double image reflections. ive only seen this at night and with this particular lens but there you go. here's an example shot on a very cold night in sapporo. not a great shot but a good example of the problem....b Link to post Share on other sites More sharing options...
rob_x2004 Posted October 16, 2006 Share #11 Posted October 16, 2006 So it is mainly a night time wide open Noctilux problem when you are shooting into point lights? Link to post Share on other sites More sharing options...
Bob Ross Posted October 16, 2006 Share #12 Posted October 16, 2006 Anyone got anything that shows a half decent filter makes any difference at all? Or are we talking about flare? I don't have any of my test samples from 3 or 4 years ago, but back then the dpr forums were full of comparisons between the older single coated filters and the multi coated ones with digital. The newer filters have a light transmission up in the high 90%s. What I saw was that the older filters produced a hazey image compared to the multicoated ones. While you can PP for haze, it isn't worth it and you could see the difference even in mundane snaps. It is easy to see where the no filter camp originated and rightly so.

AndyB :D Well Rex, you'll be glad to note there is hope, as this devil's agent has no filters on two of his four M lenses. There is a haze B on one from slide shootin days and the other has a multi coated UV. From the artistic side, if I get a filter effect in an image, I just say that is how I wanted it. Learned that one in the kitchen;) Bob Link to post Share on other sites More sharing options...
Riley Posted October 16, 2006 Share #14 Posted October 16, 2006 being the ultimate capitalist i like both perhaps not at the same time though i will only keep quality filters such as UV, and use them when out in the field when the sort of aerobic contaminants can be unpredictable i often try to use a hood just to save getting the lens knocked mostly i either or both for protection, as they are cheaper than lenses, and be happy to take them off when optimum results are required.

rvaubel Posted October 16, 2006 Share #15 Posted October 16, 2006 .......mostly i either or both for protection, as they are cheaper than lenses, and be happy to take them off when optimum results are required............Riley "happy to take them off as required" is rhe hard part to decide. Although filters don't flare all the time, it's amazing how many times they do. I never was really aware of the seriousness of the problem until the coming of digital. Once I could get instant verification of flare problems I started checking. The results are pretty horrifing, even with multi-coated filters. Some kind of flare is almost guaranteed in backlight situations. Bright point sources at night are another killer. Its just not worth it. The other factor is that dirty lenses don't even have that bad of an effect. A moderate amount of dust, grime or fingerprints really doesn't do all that much. And it worst you get a little reduction in contrast. I've done "before and after" tests on pretty dusty lenses and haven't really even been able to see the difference. The problem is that filters are FLAT which seems to cause most of the problem Actually, the only reason I clean my lenses at all is to make them look good. There is really almost no functional reason to clean them at all That being said, if I was going into a dust storm...... Rex Link to post Share on other sites More sharing options...
ho_co Posted October 16, 2006 Share #16 Posted October 16, 2006 To put it simply: 1) A filter will protect the lens. 2) A filter cannot improve image quality and can only impair it. Reason--you're adding two glass surfaces that weren't calculated into the lens formula. 3) A hood cannot harm the image quality and can only improve it bykeeping out non-image-forming light rays that can degrade the image. 4) You should always use a hood, PARTICULARLY if you use a filter. Reason--you are moving the front glass surfaces forward of where the designer put them (filter in front of front element) and thereby adding surfaces prone to catching unneeded light. 5) All the above goes for indoors shots as well as outdoors because there are usually many light sources and specular reflectons indoors. My rule: Get a filter for every lens, and never use it. --HC Link to post Share on other sites More sharing options...
gurtch Posted October 16, 2006 Share #17 Posted October 16, 2006 Hi all: I have a Leica 24mm ASPH. I had a very high quality Contax MC UV filter (55mm), and when I attached it, the Leica hood would not fit over it. I bought a Heliopan UV "slim" filter and the hood now fits with the filter in place. The Heliopan "slim" is different than the "wide angle" filters, as it actually has threads, but the filter is measurably slimmer, and slightly smaller outside diameter, than normal filters. Regarding using UV filters, it depends on the work you do. 99% of my work is done on the NJ shore, on a barrier island, on the beach. Very fine sand is almost ALWAYS blowing (stings your face). Then there is wind swept salt spray. I constantly have to clean my UV filters to get the sticky salt haze off of them. Consequently, I have separate UV filters for all my lenses, and they never come off (well, hardly ever). I use Hoya MC and B+W MC high quality filters. I seldom shoot night scenes, so reflections are not a problem; however if I did, I would probably remove the filter. Having said the above, most of my daylight seascapes are taken with a polarizer, so I do remove the UV first, of course.

jrc Posted October 16, 2006 Share #18 Posted October 16, 2006 I use filters when there's lots of dust, sand, or spray, or if I'm bushwhacking through the woods. I don't use filters when I'm mostly working from my car on a normal day, just out roaming in easy country. I do use a hood most of the time. I bought a set of filter wrenches for almost nothing, and since they're very flat and light, they're easy to put in the pocket of a camera bag and you never notice them. Only used them once, though, and even then I could probably have figured out something else. JC Link to post Share on other sites More sharing options...

Also, I need to add, in low contrast situations, a filter does no harm. I do have filters for all my lenses, primarily Heliopan Ultra slim filters (with the brass threads) Rex Link to post Share on other sites More sharing options...
