I've got -2.75 & -1.75 eyes. Should I round up or down to the nearest diopter? For each eye. 2.5 or 3 for the 2.75 eye & 1.5 or 2 for the 1.75 eye?

Because of the difference I would suggest buying 1 pair in each of the diopters you need and swapping out the lenses. For me the difference was only 1 point so I went up a half. They've worked out great.

Two easy ways to solve this issue: There is a company called Platina (they also sell on Amazon) that sells the Corrective lenses separately so you can go that route if you like but it is more money. Second option: determine which is your DOMINANT eye and buy a pair with that correction. 99% chance you will NEVER notice the difference since your dominant eye controls most of your "vision"

So you have the option to have a different strength for each eye? I did not when getting swim goggles and went with something in the middle, so in your case, either 2 or 2.5. I have one eye too strong, one not enough, but that does not seem to be a problem.

I set the focus for one eye in the non-diopter lens with the center focus ring, then looking at the same spot with the other eye, adjust the diopter adjustable lens to focus. Once this is done, you should be able to focus for both eyes with the center ring. Each person may have to adjust to suit their own vision, but if only one person uses the binoculars, they shouldn't have readjust the diopter to focus with the center ring. Note your diopter position for the purpose of quickly realigning if someone changes your setting,

I think it is best if you start with 0.5mm because it is safer and not painful and if you like it and get used to it get a replacement head of 1.0mm.Also depends on the areas where you want to use it, use smaller needles as a beginner or to use in gently areas such as around the eyes. hope this helps.

15X is if you want to see extremely close! I have bad eye sight, so I need this. Only bad thing is you can not see your whole face at one time. For normal use, I would suggest a 7X. 15X you can almost see every pore on your face, and only one eye at a time pretty much. Hope this helps.

The CPC is listed as using 1.25" star diagonal. You should be able to use the 2" star diagonal in this kit to use the eyepieces in this kit. You will need to remove the 2" diagonal and reattach your 1.25" diagonal to use your 1.25" eyepieces.

Thanks for taking the time to reply. I suspected as much, so I have just been using one at a time. Nice to know that I needed to, and should continue to, in the wide angle range.

You can choose between 60, 90 and 120 deg angles in the menu. Even the 120 isn't really fish eyed where as normal fish eye lenses distort around the edges. Hope this helps.

My brother has loan his 50 1.4 to me. I like. I may get the 24-70 2.8 - we get so many positives about it. Use the 24-70 indoors and the 4f lens where there is good light??Thanks for your suggestions.

Hi Anthony, The correct magnifications are 1.5x, 2x, 2.5x and 3x. The magnifications in the current video needs to be updated. We sincerely apologize for any confusion.

Remember, the minute you go from 1x1 up the power scale, you change your field of view!! If you have vision problems, then who cares!! Target acquisition during combat is probably 75% reflex. Good vision, good reflex, breath control, and trying to control adrenelean rush is paramount, but if you are shooting 300 yards or more then acquiring your target should not be a problem with a 2x magnifier. For closer targets stick with the 1x unless you have severe vision problems. ENJOY!!!

I read that it'sto do with the exit pupil size and why I went for 15x70. Apparently adult pupils (those over age 25) have a pupil diameter of around 5mm. So with 15x70 binoculars that's an exit pupil size of just under 5mm (the 70 divided by the 15). So essentially these will let in the maximum amount of light into your eye thus giving the sharpest and brightest image. I believe that if you buy 25x70s then the images may appear quite dark. PS still waiting for mine to arrive so and brand new to astronomy so happy to be corrected. Hope this helps.

I am actually hesitant to answer this question, because obviously no one here read the product description. On the first line it states "8 1/2-10 1/2" eye relief". So 10.5" at 2x, and 8.5" at 7x.

2.75 is not a standard lens magnification offered by the manufacturer in this style, so most vendors do not carry it. Some vendors do carry it as a specialty item, however. The vendor LittleGorgeousThings does have the 2.75 lenses at this time, but it may not be listed in the Amazon product catalog as an option; you would have to contact them directly to get it put in your glasses.

Id say pick the 17-35 if you intend to stay on DX size for another 5yrs... the 50mm covers the middle of the 24-70 so moving your feet will cover that distance, but the 17-35 will allow for group shots and landscapes/buildings... the 24 will limit that somewhat.... my2cents!

Download the user manual, there is a chart with that info. I have 92" (diagonal) and am at 14'2" without adjusting the focus and so on. You'd need to be back some .... Mines a 3010, so YRMV.... It's worth the effort to get it "just right"....

They adjust for interpupillary distance at the hinge. The adjustment is so wide, I can't imagine them not fitting everyone. Hold them up to your eyes and move them in and out until the two circular images merge into one. The interpupillary distance is set. Then focus them until the image in the left eye is sharp. If the right image is also sharp, the focus is done for that distance. If the right image is fuzzy, adjust the diopter ring on the right eyepiece until the right eye is also sharp. From then on, focus is done with the big wheel in the middle. Easy peasy.

I can confirm that the best fitting sizes are #44 for the objective and #13 for the eye piece. The good folks at Cabela's let me try a few sizes on the display scope so that we could determine the best fit. While some have said that #14 should be the right size for the eye piece, I found that it was simply too loose. #13 was a tight fit, but was more secure than #14.
