Author Topic: Magna Com 65 vs Magna Com II Don Furr Jedi Master Film Handler Posts: 509 From: Sun City, Ca USA Registered: Nov 2002 posted 10-09-2009 08:22 PM                     What is the difference between the two Magna-Com's?  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 10-09-2009 08:31 PM                     One is a coke bottle and the other is a pepsi bottle! There is simply no other apt description for either of them...

One is just newer than the other?  |  IP: Logged Victor Liorentas Jedi Master Film Handler Posts: 800 From: london ontario canada Registered: May 2009 posted 10-09-2009 09:31 PM                     I have compared both and find the ISCO Magna-com 65 to be brighter and sharper than the Kollmorgen Mag 11.  |  IP: Logged Don Furr Jedi Master Film Handler Posts: 509 From: Sun City, Ca USA Registered: Nov 2002 posted 10-09-2009 09:43 PM                     Both of the lens I'm talking about are Kollmorgans.  |  IP: Logged Victor Liorentas Jedi Master Film Handler Posts: 800 From: london ontario canada Registered: May 2009 posted 10-09-2009 09:58 PM                     Oh... Coke and Pepsi i think.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 10-09-2009 10:25 PM                     Sorry, even the ISCO version has too much distortion using it either way and it also lowers the contrast range considerably. The lens has no light baffles inside... So I'll rate it a Dr. Pepper!  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 10-10-2009 02:27 AM                     Don, I won't confuse you with soda comparisons. They both suck. Don't use either. If you must, then just switch over to blu-ray with a cheap video projector. The end result will be about the same.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 10-10-2009 06:57 AM                     Sorry peoples...I've used the ISCO MagnaComs with GREAT success...sharp images too. In fact, they are almost a must for curved screens as the pin-cushion distortion they introduce will mate up well with a curved screen's barrel distortion. Don't be afraid of the Isco Magnacoms (later known as Zoom converters type L and S). They are not right for all applications and one must know what they are doing with them but they can be VERY handy tools...they are just not ZOOM lenses...they only seem to be.

If you like your available contrast range shot to hell go ahead and use em.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 10-10-2009 12:28 PM                     I use MagnaComs a lot and really have had few issues with them  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 10-10-2009 02:27 PM                     Mark is right on the money with this. Contrast dies with those damned things. And Steve's explanation is why I refuse to install those silly curved screens. All they do is introduce distortion and further kill the contrast as the two sides work against each other to wash out the image. Magnacoms = suck Curved screens = suck Curtains = awesome  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 10-10-2009 03:31 PM                     Magna-Coms (at least ISCO "Zoom Converters" are valuable tools Curved Screens are the best, Torus Screens = Suck Curtains are indeed great. As for Dwight...he and I differ on some things, for sure...as for Magnacoms...perhaps Schneider's loses contrast...the ISCO's form the mid/late '80s seem to do just fine...especially the type "S".

(He had previously said that Magnecoms don't lose light.) Therefore, we have created a lens with gain!!! I suggest that large screen theatres use a 500 watt bulb along with at least 10 Magnecoms.!!! Steve: I, too, have used these on deep curved screens to help with focus. Works great if you know what you are doing. Louis  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 10-10-2009 04:20 PM                     The Zoom Converter is different from the M65 Magacom. First you guys need to learn what part is what before you can claim to know what you are doing. The Zoom Converter does not have quite the contrast issue the M65 does but it still DOES degrade the contrast ratio the prime lens is capable of. Mark  |  IP: Logged
