Do the +2 masks have an insert lens in the bottom? I am looking for a single lens, not a bifocal, that has +2 magnification. I was told that they all only have magnification on the bottom portion of the mask, which is not what I am looking for.

I think my lens are one complete lens at -6. I don't know anything about magnification at the bottom. They are not for reading, so I think they are one complete lens at whatever you order. I am very happy with mine.

Standard Gunnar glasses have a +1.2 magnification to them, per their website:http://www.gunnars.com/gunnars-vs-cheap-alternatives/

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

I wouldn't know about that. All I know is it was very disappointing, and I do not believe it has 3X magnification. At most, 2X.

Her is two thoughts, 1st you can use a minus 1 and that may give you the rsange you want but I took the 2nd way which I purchased a -2, that way I can use the plus adjustment to get the proper adjust. Don't to purchase an eye cup for the corrective lens.

I just got one and couldn't see anything either. When I took it out of the box there was a 3" lens that was separate. I thought it was an extra. Turns out that it needed to be placed in the end of the telescope. If this is your case, unscrew the plastic ring at the large end of the telescope (remove the sun shade piece first) place the lens on top of the other lens and replace the plastic ring. There should be 2 lenses at the end. Once I did that I could see great! Start out with the largest eyepiece (25mm) to find objects easily.

The lens is not tinted. Personally, I wish it was and it is hard to upgrade for this mask. My advice to you is to get a v flex rather than the helix as with the v flex you can get tinted lens.I hope you enjoy whatever mask you decide to get!

From what I understand the IS feature allows you to shoot "hands free". Of course if you use the lens on a tripod (like I do) if you had IS you would have to turn it off. This is an amazing lens and definitely my favorite. For Portraits I would check out the 24-70mm 2.8 IS L Lens. I have not tried a 2X extension with this lens but at this time I really don't need one. However, if you are thinking of using 2X extensions, I imagine that you would be shooting with a tripod and would not need the IS feature.

No, it's not an add-on or "auxiliary" lens -- it's a full lens in itself. It goes on your DSLR *in place of* any other lens, not added on to an existing lens.

I was able to fit in my smaller eyepieces in the adapter. There is a knurled screw that will hold the eyepiece in place. I've also found that it isn't designed to be used as a primary focus adapter unless you have a low profile focuser. Has anyone been able to find any larger eyepieces that will fit in the adapter?

Unfortunately I could not find a bifocal mask with correction for both far and close up vision. I bought a Promate mask with +3 correction for close up vision with the intent of reading the pressure and depth gauges while SCUBA diving and seeing the screen of my underwater camera. However, it doesn't work well with the camera because I have to raise my head to an uncomfortable position in order to see the screen while taking a photo or a video. I also bought an IST mask with single +1.5 correction, which is fine for me for far away vision, but is only of some help for reading the gauges and looking at the underwater camera screen.

No, there is no normal magnification, only 5X. This mirror is really a great mirror! I don't miss having a smaller magnification mirror.

Hi, it does have magnification, but through the included software (via download). It's a digital zoom. So you do lose some quality. To attach, you need to remove the existing eye piece. There is a very small screw holding it. Unscrew that and then pull out. For my microscope, I did not need any of the included adapters. Note installation may be different if you have a different model microscope. Hope this helps.

Hi Ray. There is no magnification. It's just an eye cup that makes it easier to use the viewfinder in that it keeps your face a bit away from the back of the camera and does block some light from entering from the rear of the viewfinder.

Some have different colors like azure(blue) on the inside frame and black outside so it has to do with the color and also GR004 gives you the option to include magnification on the lenses if you want or need that. You can look at the description of each to see if its the one you want. You can choose no magnification on the ones that offer it and the only difference would be the color.

I would not stack more than 2 filters. There probably won't be any effect on sharpness, but you could get vignetting depending in the lens. Try it, if it works fo9r you, it's OK.
