Hi, James. I'm not exactly clear on what you are asking.its A900 CZ 1.4/85
does having a VU filter on anything to do ?
I'll try C1
Thanks
James
A UV filter may very well be an issue. When I received the A900, I noticed more aberration with UV filters compared to my APS-C cameras (and I never used UV filters on MFDB,) so I quit using UV filters unless harsh conditions require it. These were expensive Heliopans, BTW. I don't really want to open this can of worms on the debate regarding whether we should take off UV filters or not, but you may want to test it for yourself.
After being brow beaten by the likes of Thom Hogan and Iliah Borg in regards to UV filters hurting IQ**, I still resisted removing them for a while. However, when I received the A900, I was just running around the house firing test shots wide open on a couple of primes, and I noticed some shots were a bit soft with some purple fringing in the highlights. I removed my Heliopan multicoated UV filters, and the problems were gone. I haven't really done a scientific test, nor have I tested things since that day, but it was enough to push me over the edge. Now I just use them in harsh conditions.That is interesting Douglas. I was assured by Zeiss that high quality UV filters do not cause any visible image degradation and they even recommended using one in order to avoid cleaning the lens front element. They recommended B+W and Heliopan (obviously because they use Schott glass, which belongs to Zeiss).
Yeah, but propper cables make around 5% of the total costs that a recording setup comprises. The Dynaudio Air are like the A900 in the DSLR world, you would not have a cheapo cable running to your console either.ok, back to the store tomorrow , couldn't we have chosen a cheaper hobby :thumbup:
Thanks
