NEW Medium Format Stereo Viewer

With internal illumination, focusing & interocular adjustment

Same wonderful Achromatic Lenses as its "steal-the-light" brother, but many new extra features:

Focusing	Interocular Adjustment
Battery Operated (3 x AA)	Momentary Light Switch at the top

The viewer has been reviewed by several members of the MF3D-group @ yahoogroups.com email discussion list.  Here is my summary of the viewer's features:

LENSES:  The lenses are the same as the STL viewer, which are very good coated achromatic lenses, 32mm in diameter and 75mm in focal length.  Mike Davis writes: "Just as with the STL viewer, these lenses are sharp right into the corner of the frame, with no apparent chromatic aberration and just a hit of pincushion distortion."

ILLUMINATION: Illumination is provided by an array of 18 LEDs.  The light is very uniform and sufficiently bright, with good color.  The momentary contact switch at the top is working very well.  The viewer is powered with 3 x AA batteries.

The diffuser can accumulate dust rather easily, but the viewer can be easily taken apart to clean the diffuser (see details below)

FOCUSING: The viewer offers 18mm focusing range.  The first batch of these viewers had the infinity at the extreme focusing range.  However, in this 2nd batch, this problem is corrected and now the viewer will work well for ALL users, young and older, myopic and presbyopic.

INTEROCULAR ADJUSTMENT: The interocular adjustment is via simple friction and it goes from 62-66mm.  I tend to use my viewer with the lenses at the maximum separation.

In his review, Mike Davis concludes: "There's a lot to like about this viewer, just as it is.  It's cosmetically attractive, instantly comfortable in the hands, compact (perhaps to a fault).  I think it will be well-received by the majority of users....  It's the only illuminated MF viewer available, so for that reason alone we should be appreciative."

How to Take the Viewer Apart - AT YOUR OWN RISK!

Start by removing one single screw in the battery compartment, seen in the top left picture.  From there, carefully remove the light panel, which is supported by two hinges in the opposite side.  The hinges are plastic, so be careful not to break them.   The pictures below show you some of the steps you will go through.  PLEASE do this at your own risk and be careful!  The viewer in not meant to be disassembled and assembled too many times.

The fine print:

1. I accept most forms of payment (money orders, personal checks, PayPal).  I do not accept direct bank transfers or checks paid to foreign banks due to the high fees from US Banks.  Please use eBay' s checkout and go ahead with an electronic payment after the auction is over (please make one payment for combined purchases) or wait for me to send you an invoice using eBay' s check out system.  
2. I use the US Postal Service, I will ship anywhere in the world and I try to get you the lowest shipping rates.  I will combine shipments too.   For international customers, I am flexible in custom form declarations.
3. I always leave positive feedback after payment, but sometimes I am late... If you have a problem with your purchase, please let me know as soon as possible (remember, I sell a lot of items on commission and I need to close these accounts).  Contact me before leaving non-positive feedback (including neutral).  I will do my best to resolve any problems. I accept returns for most of the items that I sell, but I can only refund the selling price, not shipping, unless if there is an error in the listing..
4. I appreciate your business and hope to see you back!
