That's a great image Kryss, from a great lens.
Does the Ghostless UV Filter improve the image, or does it just not detract from an unfiltered image? If that make sense? The use of clear / daylight / UV or protective filters is always up for debate with the haters saying anything in front of the lens must degrade the image, with ghosting being the main reason against using a 'clear' filter for lens protection. So does the filter just 'not ghost' - or does it add something other than physical protection? _________________ LENSES & CAMERAS FOR SALE.....

Thanks David,I do not see any degradation on shots taken with this lens and Pentax being known for first class glass for medical as well as Photographic use would not put a filter on market that was inferior,also it wasn't cheap. _________________ Do not trust Atoms....they make up everything. |

Yes, the front element is tiny and set back about 45mm from the filter thread - making the front element more difficult to clean so a filter would useful, but the 45mm gap might introduce problems that aren't apparent with a lens where the gap is a few mm.
I rarely use a filter, only sometimes for protection on a windy day to keep dust or rain off a front element and I don't worry about wiping a filter clean on my shirt. And a lens like this Tak' Macro is exactly the sort of lens I would want to protect. _________________ LENSES & CAMERAS FOR SALE.....

?
Mechanical differences, to achieve 1:2 to 1:1 magnification range -- unique helical extends both ends of lens(!) -- the 1:1 version aperture has preset mechanics.
The optics of all these is identical -- also, both my copy's lens coatings looked identical, unlike the differences seen between other Super- and Super-Multi-Coated lenses, my 1:1 Macro-Takumars appeared to have the S-M-C coatings...
All of them have the deeply recessed front element.
The Ghostless filters I had were top quality comparable to best filters available from any manufacturer (at the time).
There is the possibility the filter may provide some kind of image improvement in the 1:2 to 1:1 magnification range, which only one of the lenses is capable.
I got best results FULLY stopped down -- with Canon 5Dc full-frame sensor I could not see any image degradation from, say, f/8 -- the lens is very very sharp throughout its operating range; a conservative lens design.
I have never before heard that reason why Pentax changed from 1:1 to 1:2 model. Obvious, the mechanics cost less to produce. Of course there is some image degradation on entering the greater magnification range -- that happens with ALL macro lenses; nothing special to the 1:1 Takumar. Is there a source for that comment? _________________ ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮ like attracts like! ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮
