which is the maximum aperture obtainable?

It depends on the lens ie:if the lens f/1.4 that's the max at open closed f/16 and this adapter is only effective on crop sensor

I use the 50mm f/1.4 for almost everything. Although it is harder to get objects from far away, it is amazing what you can get out of it. The shallow depth of field is just top notch.

You can get various degrees of magnification from a short distance away (I don't have it out right now to measure - lets guess about an inch) on up to right up to the clear plastic barrier; from that point if you cut the product into approximately a 1/2" diameter circle, then you can get further magnification up into this plastic 'shroud'. Obviously trying to scan along the surface will have to be what ever max magnification you can get outside the clear plastic piece. Note that there are no indicators that tell you what magnification you are at.

"When seen in the picture, The max height of field of view is approximately 0.85mm with 10X objective. The width is longer about 1mm."

You need to find the aperture of your scope. The typical maximum magnification of any scope is 50-60x this number. So if your aperture is 2.4", then the maximum magnification is somewhere between 120x-142x. For example, a 20 mm eyepiece used on a 1000 mm focal-length telescope would yield a power of 50x (1000/20 = 50) and a 10 mm eyepiece used on the same instrument would yield a power of 100x (1000/10 = 100).

REFLECTOR=actually the higher aperture size means more lightgathering capacity to help see the most distant=dimmest objects and reflectors have less chromatic aberration than refractors, ergo=deep space capability

None off the above, neather summable nor focusable, its beam is so strong you would not need the mentioned. Unit comes with 5 mode. Strong, med,low, strove, sos. You would be amazed of how strong ana well build.

Thank you for your inquiry. In regards to your question, the minimum aperture of this lens is f/22. Maximum being f/1.8, if you have any additional questions or concerns please feel free to contact us directly at 800-991-3350.

Yes, it is. The focal length and aperture value cannot be mathematically separated, and must both be multiplied by 1.53.

I'm assuming your referring to beam focus or dispersion. I don't have exact degree but this is more of a narrow focus beam. Probably no more than 20 degrees.

Not sure about maximum but I primarily use a Nikor 28-70 which is 77mm diameter. Hope that helps.

8x Optical Zoom and Up to 16x Clear Image Zoom... I think that is the digital zoom

Unfortunately, the focus to infinity is not available: 2.5 - 3 meters (8-10 feet) is maximum.I use this converter with Nikon D5100 and with the specially adjusted, the old Russian lens Jupiter-9.http://cameras.alfredklomp.com/jupiter9/This is a very specific lens.https://www.facebook.com/photo.php?fbid=10202107820475164&set;=a.3021099764648.2131658.1177290511&type;=1

This is a speedbooster. The maximum f stop is multiplied by .7. For example if you have a f2 lens it will increase the light gathering to a f1.4. Also makes the lens wider by 0.7. If you attache a 10 mm lens it will be as if you attached a 7 mm lens times the micro 43 conversion factor.

yes it does give you some settings of aperture for different situations. Not as in-depth as it could be.

I'd always prefer a more extreme wide angle... So the 24mm is my favourite. The f/1.4 aperture is all the more glorious when the angle is wider.
