Macro Extension Tube Ring Set for M42 Screw Mount


12 in stock


– Macro Extension Tube set for SLR cameras with M42 lens mount is composed of 3 extension tubes – 7mm, 14mm, and 28mm with male and female M42 screw mount adapters. Mount the tubes between lens and camera body to get your choice of macro ranges – 8 combinations in total
– 3 extension tubes – 7mm, 14mm, and 28mm
– Mounting Extension Tube in between the camera body and lens will create more distance between the lens and film plane. By moving the lens further away from the film or digital camera sensor, the lens is forced to focus much closer than normal. The greater the length of the extension tube, the closer the lens can focus
– Use this set with your normal lens and you will get the quality, which is as good as the lens and the size, sharpness and versatility is perfect for the macro and close-up pictures
– With all M42 mount lenses you will need to use manual focus and manual aperture while shooting. Please make sure that your M42 lens has a switch or button to put the lens into stop-down mode, commonly referred to as the Auto-Manual or A/M switch

How to use:
Please note: when tubes attached, you need to do all manually, and it is important that you use lot of light.
There are some main steps how to use tubes:
1) set your lens to maximum aperture (recommend);
2) set-up camera and lens to manual mode, switch off and detach the lens;
3) attach extension tube between the camera and lens (look for red dots and align on mount collars; attach same way as lens);
4) put your camera on tripod, or better on rail system;
5) put object close to the lens and use lot of light (2-3 flashguns, or 3x 500w lamps, or at least 1 strobe-light, or take pictures outside in bright sun);
6) increase ISO, decrease shutter speed;
7) focus by moving camera further or closer (if on rail system), or use manual focus ring on lens mm by mm (very slow) until object in focus. Please remember that DOF (depth of field) is very small.
You don’t need to use all tubes together – you can combine tubes – shorter length you use, in viewfinder becomes lighter, but again not as high magnification as with all tubes together.
