That was in times of analog photography different - and this for two reasons:
1. The main reason: The footage was indeed sensitive to UV light with its layers in different ways.
2. Most have high quality lenses sold in the heyday of analog small picture photography then usually only 5-10 lenses / elements. When you buy a high-quality lens today in the age of digital photography, which has then one with 10-20 elements, sometimes even higher. Since each element glass - tempered the more - absorbs UV light, was at the time of analog photography is a risk that UV light can be up to the film plane, significantly larger than today to the sensor plane.
As a dedicated amateur photographer and self-developing in the 70s and 80s, I can only confirm this. A pre-screwed UV filter or its Skylight variant were small wonders when shooting with large sky Share (blue with white clouds) and even though Dunst Added to this was: richer colors, higher contrast between blue skies and white clouds, particularly impressive even when s / w-photography and Development.
My forth above physical skeptical opinion I have experimentally occupied personally the use of UV filters on my DSLRs for me to get: No specific visual impact on the images due to the UV-blocking action. How should: In 20 glass elements - which are also top paid and intoned another - what is to come nor to UV light? And that today's digital sensors react to UV light, I can not understand anyway, would certainly scientifically ne very special challenge to occupy the :-))
What remains is the protective function of the UV filter for the lens:
- The mechanical protection as "Always top" (the must-mounted sun visor take with me) does not go with me because I photograph full frame, while often more filter (in particular pole filter) use (avoid vignetting by only one pre-screwed filter).
- In this respect I use on all my lenses the respective UV filters situationally. He draufkommt when it comes in dusty, sandy terrain, to protect the lens from becoming dirty. So: When Scrambling in the mountains, on uneven terrain, through the bushes and undergrowth, especially if it's very dry. Also on the sandy beach, especially if it's windy, with salty air anyway.
And since I have to say that three Walimex SLIM MC UV filters of different sizes on three of my lenses do their job great!
So far I could (for years) or similar no dust account for between filter and lens. Because:
- The filter glass is firmly seated in the metal ring - in spite of many on and unscrewing.
- The thread is going very well. The filter is easy to screw on and off, he sits tight because nothing stuck. No trace of Gewindeverschleiss previously.
- If the result of the intensive use someday change (thread faulty or filter glass loose in the metal ring), then there is just a new Walimex - at the price-performance ratio is an investment that you like is taking no regrets and anger!
To summarize:
I am - regarding my mission profile - fully satisfied with the Walimex Slim MC UV Filter:
- Suitable Slim filter Vollvormat.
- He is well made.
- Filter glass is firmly seated in the metal ring.
- Thread runs smoothly in spite of many changes.
- It protects against dust and other contaminants.
- The value for money is hardly beatable.
- Strange picture (due to reflection of light components through the sensor to filter) so far I could not make out.
Finally:
What would be the honorable Gymnasialprofessor and physicist Bömmel from Feuerzangenbowle of himself when he held a steam engine a UV filter would explain his Prima formers. Maybe so:
"So, wat is de UV filter? As more point us Janz stupid. Also Pfeiffer!
So, dat is de round Jlas - for passing itching. And why is en Medallring. And who of the enes page en Jewinde. Which is screwed to it somewhere, then that's janz tight. "
Bömmel drops his monocle and clamps the filter instead eye.
"Wat see more? Dat UV filter is wat en monocle is. Dat protects Ojen with dirt!"
I hope this review was helpful to you! For comments in turn thank you!
