Back in April 2012 Grays of Westminster sold the ultra rare Nikon 6mm f/2.8 fisheye lens for £100,000

The 220º Nikkor fisheye lens weighs 5.2kg, measures 171mm in length and has a diameter of 236mm. It’s one of the few 220º Nikkor fisheye lenses ever to be made.

Last week another one turned up on ebay : Nikon 6mm Fisheye on eBay

This one failed to reach the $49,500 dollar reserve (approx £30k), which compared with the previous sale price was an absolute bargain.

Even so is any lens really worth this kind of price tag?  Would you pay this kind of money for a lens?

A tele-converter is a budget accessory that will increase your photography options. The most common one is a 2x converter that doubles the focal length of your lens. Your 50mm lens becomes 100mm, your 70-300mm zoom becomes 140-600mm.

Vivitar made a number of converters through the 70s and 80s.

Teleconverters are ideal for photography such as sports and wildlife.

Advantages:

• increased magnification
• light weight
• cheap

Disadvantages:

• light loss
• quality degraded
