300mm
The EF 300mm lens refers to a family of telephoto prime lenses made by Canon, five of which have been sold to the general public and one of which was only made on special order. The lenses have an EF type mount which fits the Canon EOS line of cameras.
When used on a digital EOS body with a field of view compensation factor of 1.3x, such as the Canon EOS-1D Mark IV, it provides a narrow field of view, equivalent to a 390 mm lens mounted on a 35mm frame body. With a 1.6x body such as the Canon EOS 650D, it provides a narrower field of view, equivalent to a 480 mm lens mounted on a 35mm frame body.
This lens is most commonly used by sports and wildlife photographers, but is short enough to be use for extreme close-up portraits. Because of its rather high native magnification, it can be used for some macro type photography.

Hello
I have had to adjust a sink hight by several mm. Now my bathroom basin 300mm flexi is a fraction too short. It does up but under tension. Is there a bush of some sort that I could use to extend by a few mm. Ideally 1cm or more. I’m thinking that a 500mm would have too much slack. Or would...

We have some large Britannia brass taps, one of which has begun to leak pretty badly because the washer that should be attached to the tap spindle has degraded and is pulling way when the tap's opened.
The trouble is, the washer is huge: 1 1/4" (300mm) by the looks of it.
Does anyone know...

Does anyone know if you can get the below product in either 100mm or 200mm lengths. All the majors only seem to stock it in 300mm and 500m.

Dear Friends
Just thinking about things!
If you have a piece of 15mm copper pipe 500mm long, and you need to bend it at say 300mm to go around a corner (90 for arguments sake), how do you do it?
i.e Do you measure 300mm along pipe, put pipe in bender, 300mm mark aligned with edge of former...
