Canon EF 1200mm f/5.6 L USM Lens

The longest and perhaps the rarest full autofocus lens in the world - the Canon EF 1200mm f/5.6 L USM Lens.

The new EF 1200 was then marketed by Canon in July, 1993 with an annual production volume of around 2 (that's right - "two") lenses. The EF 1200 L was available by special order with lead times running about 18 months.
For one reason, it takes nearly a year to grow fluorite crystals large enough to be ground and polished for use in this lens. In addition, the lens is "virtually hand-made".
The 1200 L has an 8 blade aperture, but evaluating bokeh was not easy as everything not in focus is always a complete blur. The Canon EF 1200mm f/5.6 L USM Lens uses a Ring USM (Ultrasonic Motor) rear focusing system. This is a electronic focus-by-wire design that works very well. It is quiet and relatively fast.

For the record, the Canon 1200/5.6L USM contains 13 elements (including 2 Fluorite) in 10 groups, stops down to f32, and has a minimum focus of 45.9'. As for filtration, 48 mm drop-in filters can be inserted towards the aft section of the lens barrel.
The original price was 9,800,000 yen - that was MSRP $89,579 in the USA. And "no discounts"
