what is the focal length, i.e. how close do you have to get. I want to use this for soldering on pc boards and need to have both hands under it

Sits right on the object being viewed, very close. You need a bench magnifier lamp.

The one we have has a pretty short focal length if you want it to get higher magnification. However, if can focus farther but with much less magnification. If you are doing PC boards you may be better off with something else like a stand magnification lamp.

I dont know the focal length but have used it succesfully from 2" from the specimen to 14". You should easily work with your hands between the specimen and scope. Focus takes a minute, and make sure you buy the articulating stand. Computer viewing is simple.

You can get reasonable resolution at 2 to 3 inches. Just checked and I can get the soldering iron and solder under it without any difficulty.

Sorry it took me so long to respond. I left it at work! The diameter of larger part is approximately 4 inches. The smaller greater magnification part just under an inch. Still working great!

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.

I use one to work/solder surface mount electronics to printed circuit boards (PCBs). I love it but naturally if the parts get too small... I should have added that over the years I've use many magnified extension lights to work on PCBs, all had external springs. This light does not have external springs and seems to be much smoother when trying to position it for work. I haven't noticed any distortion when working on 0603 parts and don't want to go much smaller than that.I just ordered one for personal use.

I use this often and I couldn't tell you for sure. However, I'm freakin' blind, even with bifocal contacts lenses I keep reading glasses in all my camera bags to focus with even a 7" HDMI monitor. And it's great, magnification wise - you will nail focus far better than just using the LCD. The bigger issue of this one is using it on a rail system - it offsets your camera by 15mm left or right (depending which mounting hole you use). So you're SOL if you use a rail-mount matte box (my follow focus does fine). You need a camera baseplate that adjusts left/right to align with a matte box. I've used this on rails with huge lenses, and find lens supports still work OK though.

I'd like to know the same kind of thing: how close/far away does this or a more appropriate model have to be to fill as small as 12x18" up to a maximum 18"x27" area from a 6000px X 9000px digital image? I'd like to keep the zoom/macro to optimum sharpness setting. TIA, GEB

According to the spec the minimum focus distance is .82 ft. Of course with close up filters you can easily go closer. That is what I do.

Thank you for contacting us. As per the manufacturer, the focal length is 24-105mm. Please feel free to call us at 1-800-991-3350 if you have any further questions!

As far as I can research, it is 16.4 feet the close focus. A closer minimum close-focus distance usually means forfieting magnification. A closer minimum close-focus distance often means an reduction in overall image clarity.

It depends on how you are using it. Ideally you want it on some sort of boom mount as it works better above than beside the piece you are soldering. Also, if you lay the unit down it has decreased distance. I have found that it is good for up to eight to ten inches beside the work you are doing in the upright mode. The fan is really powerful for such a small unit.

There is a Macro Mode option. How close you can get to your subject depends on the zoom setting. It ranges from 0.4 inches to 2.0 inches from the lens, according to the user manual.

1" diameter but I have to use the mirror to get a lateral picture of welding

The focal distance is needed as if you are too close or too far from the desired object or surface , it would be blurry. Or you would not be able to fine tune the resolution on the screen. Detail would be lacking. The light power is great and produces images of great resolution. Alexys M. Sears

The requested information is not included in the enclosed pamphlet. At range of 6 to 8 inches from face focus is not possible. I agree with Rod below. Exactly. Not for craft/jewelry makers only watch repairers.

Under fluorescent lighting the focal distance was 93 inches. Field of view 4 inches wide. Excellent manual focus. Great zoom. Easy to tell manual focus with evf because it outlines the subject when in focus. Picture quality not as good as my Nikon d90, but very satisfactory.

I am at work now but I can measure it when I get home. PaulI have 4 of the 60 led Sabre lights here at work and the lens is 7.5 inches long , total length of the light is 16 3/4 inches long.

There is approximately 5" between the bottom plate and the upper arm. There is no way for the mic and your Nikon. This thing will fall apart under that load. I would not trust it with that amount of weight and that large of an investment. Remember this thing is plastic!
