I don't know but the picture leaves a lot to be desired. If I could do it all over I would get something that has a wider angle and a better picture.

Yes, 77mm. Since this is a pretty wide lens you might want to get a thin one.

It is 6.3 mm. For an engineer, it might be possible to replace it, but as an average customer, I do not think it could be replaced my myself. So I bought an adapter from 6.3 to 3.5.

Hi, as far as I know, there is no Opteka 600mm, I think you mean 650mm - 1300mm right? The one that I bought is 500mm-1000mm. The main difference is Focal Length Range and mine is a mirror lenses.

The lens you are referring to uses a 62mm filter. This filter comes in various sizes.

I don't know if it was a mistake or not, but the two lenses I received were both STM lenses: EF-S 18-55mm 1:3.5-5.6 IS STM and EF-S 55-250mm 1:4-5.6 IS STM.

Both RMR's are the same dimensions externally. These numbers refer to the area the internal sighting dot subtends. The 3.25 is a smaller dot and would be used for a precision shot under target or range conditions. The 6.5 is twice as large, and would be used for combat or competition shooting at high speed. The larger dot on the lens is quicker for the eye to locate during a rapid draw and presentation of the weapon to the target. Most seem to prefer the 6.5 and it works very well. I prefer the 3.25 as I shoot more precision than combat. I hope this helps.

if you look at the front of your lens, around the outside ring of it, it will say the size - so it might say 52mm or 48mm, etc. - it depends on the lens

95mm filter size. Do remember that this lens is f/5 up to about 170mm and at 420mm is already f/6.3 so it's not "fast" if you're considering using filters not light-friendly.Cheers.

The filter size is 67mmhttp://www.nikonusa.com/en/Nikon-Products/Product/Camera-Lenses/2201/AF-S-NIKKOR-85mm-f%252F1.8G.html

As far as I know it is 6mm. I use 6mm BBs in mine and that's all that I've used.

The lens is about 5 inches in diameter. I actually bought this for my mother, who crochets and does needlework. She loves it and has no complaints about it.

I don't see the 6.5" anywhere. We did not do the original listing and so I cannot change it with Amazon. I did measure the base of the actual camera and it is actually just a hair less than 5" in diameter. Let me know if you need anything else. Kind Regards, Perry U-Spy Store Chicago.

there's not this spec on this camera, but in my opinion they are sort of 3mm to 3.8mm comparing the angle of view of my dvr cameras 2.8 lens. 6mm won't be suitable for cars reverse, they are more specific for longer distances objects

Yes, this is a 72 mm lens. I have a Nikon 600D camera and use this lens almost exclusively. I love it, as it has so much range of focal lengths. Works very well in low light. MikeMike

The magnification with my 18 to 55mm zoom lens set at 55mm is 6X. The distance frim the subject is about 4 inches.

I would think so. It sticks on to your phone with a magnet that you put over the lens. I have never looked at a 6's lens though so I don't know if its a different size.
