Digital Lens Coatings
Digital Lens Coatings
What "digitally designed" lens would he be using on an M8 for comparison?
The main advantage of dedicated lenses for digital cameras is the more telecentric design, as the more parallel the light strikes the sensor, the better it can handle it. The effect of coating is marginal I think. Most lenses are pretty well multicoated on the rear element (all elements are coated in fact) anyway.
For cropped cameras an added advantage is the smaller size as the circle of coverage and focal length can be smaller, making them unsuitable, btw, for larger formats.
Diving in to the deep end without looking, would I be out of line to suggest a series of tests, certainly enough lenses are out there that fit the M8 to test all kinds of coatings, and even lack of coatings, in a less than subjective manner.
It is my understanding that in theory, images will be formed differently on digital medium than film.
Roger certainly put a variety of different glass on his M8 for his Shutterbug article, and as this is certainly not a new model camera, I would have thought the tech savvy group would have followed the theories with specific testing of some of the vast population of lenses that will mount to the M8 by now. Roger's article spurred me to start looking for an M8.
I was disappointed that some of the Galileo glass evidentially could not be borrowed for that article, and you are so close to Pisa Roger. ;-)
And I would be surprised if this group would not be aware of extant data on any such test.
If I have over looked published tech reports of such a test, I apologize now, and claim immunity for my lack of knowledge, and will bow to superior awareness.
Plus, as sensors seem to be changing rapidly, will the new specs hold, or will there be a coating of the month, or do somehow digital sensors conform technically? I have heard talk of larger and smaller pixels on sensors and hope others can make more of the data than can I.
I would have been happier if my M8 arrived with a clean sensor, I mean, high tech coatings do not seem to overcome dirt on the sensor.
Sorry for the digression, just everyone I have talked to seem to find the most important part of the manual is how to clean the sensor.
Regards, and Roger, how about some cheese photos, there are probably as many cheeses where you live as Leica lenses, yet you post wine photos, and a rose as well, rose is the digital wine, convenient, but yet not Margeaux ;-)
I also do not care for the prices charged by Leica for the upgrades now available, I did pay cash for the camera, if I knew there was going to be a continuing tax on it, I may have invested in even more film for my M7.
As to the reflection earlier in the thread that used sales do not benefit Leica, certainly high resale seems to benefit new sales, if indirectly. If an M9 is on the nearer horizon, I hope to be able to benefit Leica by recouping sufficient of my investment to justify the price of the M9.
