I have graduated lenses - Would I be best advised to order bifocals? And, how do you incorporate Cyl and Axis measurements?

Hi Todd, I did not see option to order bifocals so I can not comment. Best..

I do not know what 'cyl' and 'axis' measurements are, but, here is what we did:1. when ordering Speedo goggles, we got the +/- number, from our opthomologist.2. when ordering the ProMate snorkeling mask, we selected the the color and then selected the appropriate eye-adjustment (my son is nearsighted) from the "size" pull-down menu on the ProMate scuba options.3. My 13 year-old son loves the mask and was our family underwater photographer in Cozumel.

I have graduated lenses also; however, I just went with single vision lenses in my mask. Don't know about Cyl and Axis ... I didn't bother (even tho I have an astigmatism) and they worked great

I wear trifocals and the single lens correction worked just fine. I wasn't close enough to need the extra correction even when I was about 3 feet away.

When you snorkel, you wouldn't be using your bifocal lens. You should order the lens that you need for distance sight.

I agree with you, measure the Objective Lens and see if they have the size you need, no doubt they will work. Make sure to measure and convert inches to millimeters.

Hardy,Thanks for the info about getting better lenses. I just "bit the bullet" and bought the 24-105mm L lens. I have heard this same wise advice from other photographers, and I am looking forward to getting sharper photos with the new lens, and I will try to get only L lenses from now on. In the end, you truly get what you pay for.

I got 2 lenses with mine (from a year or so ago) a 6mm and a 15mm. The 15mm lens gives a wider field of view while the 6mm lens "zooms" in on the target object for more detail - they should be labeled.The cap with the hole in it is used to calibrate the telescope mirrors (it's called a Collimation cap) - you should not need to use it. If you are interested in all the ins and outs of collimation, you can google it, but I've had my scope for over a year and have not needed to go through the process.

Thanks for the info. I figured that out , finally. Don't know who gave me the misinformation about exchanging lenses, but I purchased the K-7 with the proper lens. Thanks again.

Hi, you should check lens, there should be some printing indication about your lens size on your lens

I was lucky, because the loupes that I had prior to had the 2.5x written on them. It all depends on what you need for your working distance. I am five six and I work in a dental office. The 3.5 work great for me and so did the 2.5. If you are taller I would get a rep to visit you, and then order them through amazon. Through the reps their pricing is outrageously high.

A barlow is fine. I use the GSO Barlow that actually gives you two magnification choices...http://agenaastro.com/gso-1-25-2x-achromatic-barlow-lens.html

NO. 10x25 will work but wont work well, 10 is the magnification, 25 is the radius of incoming light, its very little, you need 10x30+ binoculars for wider field of view

I'm not sure. They come in standard "reader" strengths. I suppose you could take them to your optometrist to see if they can replace the standard lenses with your personal prescription.

Hello, I would say the images for me are the same as I have the basic eyepieces and two sets of as you need two sets for the bino viewers but what I like is the eye relief that you get when looking through them and a almost 3d effect like you get when looking through binoculars. If you can afford it I would highly recomend it, not for just yourself but for other viewers as well. I have a Celestron 8SE and looking at Saturn, Jupiter, the moon, well its pretty awesome. My plan is to do astrophotography, if I was really into eyepieces I would go with the two inch and some nice Nagler eyepieces. Hope this helps, Good luck and dark skies.

Great, please let me know when you get your new ones!!!; I've got a hole burning in my pocket I fear, because I've been trying to rationalize the purchase of a pair of the "new" ones, too. I keep thinking that the Monarchs are so light and solid that I having the Monarchs at a "closer" view might just rationalize my investing in a pair of 10 X (name the lens)...I'm leaning to a 42 or 50....but I have a useless (too heavy old style, Swarovski Habicht molded porro prisms) 10X50s and my Monarch 8X42s just lifting them up to find a plane taking off and hearing them overhead and raising the bins to my eyes and pointing towards the sound all in one motion is fantastic...I love that ability...and I have glasses with astigmatism in the correction too. I just love the ease of use of the 8X42s....so I'm imagining the 10X42s would be wonderful too.but an extra $300 for just a one level bump in magnification? Whitneymuse...

The distance between the center of the pupils when focused on infinity (Interpupillary Distance)is not given in any of the specs for these binocs.Jim

Perhaps the best guide for A-mount lenses can be found on the Dyxum website: http://www.dyxum.com/LENSES/INDEX.ASP

It will be one heavy lens! I'd just get two 2.8 lenses to cover that distance!

BonGiorno, You need to provide info on what you have already. Do you have rails? RedRock sells gears for your lenses. Determine the circumference and buy accordingly. I needed the A and B gears from RedRock, purchased through B and H in New York.
