    Nikon 8x32mm Premier SE has been discontinued by the manufacturer???

    Wow! I haven't checked in with BF in awhile. Figured this thread was just another SE panic. But checking with my sources here in Tokyo and the the death of the SE is TRUE! Could only uncover one 12x50SE left with my usual suspects. Was also surprised to learn CN forums are MIA now too!

    Fieldscope eyepiece MCII 25x-75x for ED50 and ED82 - missing seal?

    Yeah, I took my zoom to Nikon several years ago and they looked it up in their parts manual and confirmed it does not have the O-ring. They even showed me an "exploded" drawing to prove it.

    New prices on Swarovision ELs

    Selling glass bangles just doesn't bring the cabbage in like it used to. Takes a lot of it to support the Swarovski clan's Euro royal lifestyle of champagne wishes and caviar dreams.

    improvements on my trustee kowa tsn 823

    The Kowa Prominar 77X series would not be much of a step down optically but certainly more compact/lighter and more robust. IMO, it is the best sub-80mm scope made.

    Swarovski Price Increase January 1st, 2014

    Me thinks Bushnell/Vortex/Leupold probably sell more binoculars in a month than Swaro/Zeiss/Leica sell in a year. They are not sweating the Alpha competition, despite Zeiss' intrusion into their space. 8-P

    How to understand digiscoping magnification

    Yes, and that is beauty of digiscoping with a small sensor compact. You can get relatively fast shutter speeds compared to larger sensor cameras, BUT the smaller sensor produces more noise at an equivalent ISO. If you can shoot the digicam at or within a stop or two of its base ISO, your IQ...

    How to understand digiscoping magnification

    Go back and read my edit of post #13. IMO, if your goal is to take HIGH QUALITY images for print you really do not get much practical advantage with the extra focal length the Swaro TSO APO offers other than record shot. Understand you will be shooting with small apertures or F14+ when you...

    How to understand digiscoping magnification

    The PRIMARY advantage of the Swaro TSO APO is that you can change between visual scope/digiscoping lens rather quickly while with the Kowa PZ it is not really practical. If your primary reason to buy either of these is for digiscoping then you are better off going with the Kowa Lens Scope...

    How to understand digiscoping magnification

    For a variety of technical reasons, you will find the ideal digiscoping effective focal length range to be 1500mm-2700mm. Anything less and you are better off with a traditional lens like the Sigma 50-500. Anything more, and shutter speed gets so slow and ISO gets so high you have a hard time...

    How to understand digiscoping magnification

    Pretty simple really. In this configuration, the 88x w/PZ adapter combo provides a zoom range of fl=680mm-1000mm/F7.7-11.4. This is the standard true focal length format used all 35mm SLR camera lenses. But your Oly's sensor has a 2x crop factor so the angle of view of this lens is equivalent...

    Nikon M7 8x30 vs. Kite Lynx HD 8x30

    Jan, my friend is strictly all about the birds. He could really care less about optics. His scope had the fungus for as long as I've know him, 4-5yrs now. They did give him a loner scope while it was away being repaired but he didn't even know the model, just that it was one of the "newer ones."...

    Nikon M7 8x30 vs. Kite Lynx HD 8x30

    1 year, just like with Zeiss, Leica, Kowa, Pentax, Canon, Vixen and Nikon, et all.

    Nikon M7 8x30 vs. Kite Lynx HD 8x30

    In Japan, all the OEMs only offer 1yr on sports optics. My friend just had to spend JPY40,000 to have his ~10yr old Swaro HD cleaned of fungus on the prism.

    The new Nikon Monarch 7 8x30 is very nice!

    Let's not forget CARL ZEISS uses fiberglass reinforced polycarbonate bodies in its top end FLs too. Many combat weapons and the front and rear ends of most modern vehicles use the same plastics. And many of aspheric lens components used in high performance optics are made of plastic too. So the...

    Nikon Binoculars for Comet Ison.

    Well it seems ISON didn't survive its encounter with the Sun. Feeling kinda sad about it today too. Was really hoping it would live up to the early hype of being a bright naked eye object in the holiday skies.

    I use the foam plug that was in the OEM softcase that comes with the ED50. I cut it out and put a plastic zip tie as a pull loop. I keep a small carabiner on my tripod I can hang it on when observing.

    The ED50 objective is susceptible to both dew and off axis glare and needs a longer lens hood to mitigate these problems. Look for something ~3cm in length at a camera supply store, either aluminum or collapsible rubber that screws on via the filter threads.

    That eyepiece works in the ED50. It just suffers a little vignetting/darkening at the edge.

    new Kowa TNS Pa7

    Interesting accessory. Generally this kind of eyepiece projection photography does not give good results unless the image is heavily cropped.

    Nikon Binoculars for Comet Ison.

    Guess no one has actually made the effort to see the comet yet? I think it is supposed to peak in brightness today. Problem is you have to have an unobstructed view of the ESE horizon and be up to see at 5:30am. Though we have been lucky in Tokyo with crystal blue skies for the last week, the...

    Question about glue on Kowa TE-10Z 20-60 eyepiece

    Yes that is the silicon sealant for the optical window that covers the intenal lens elements. Sorry you find it nasty. Be happy you didn't peel it off.

    Question about glue on Kowa TE-10Z 20-60 eyepiece

    That is a silicon seal for the optical window that keeps the eyepiece waterproof. Most eyepieces for other brands are not sealed or waterproof. You screwed up.

    18X or 15X Canon Is ?

    IIRC, my Canon 18x50is weighed ~1400g including the OP/TECH bayonet strap and metal dew shades. The ED50 on modified Velbon Ultra Maxi L as seen in the attached pic weighs ~1550g. I can only guess the brightness difference is to greater transmission in the Nikon.
