The need for speed: Four crazy 90mm f/1.0 Lenses

Most über-fast lenses (with f/1.1 or faster aperture) do have a focal length between 25-50mm. But there are some (crazy) exceptions. Take a look at the follwoing four items (clicking on the link will show you the lens on eBay):

1) FJW Industries Lens 90mm f/1.0 } if ($loc == 'ES') { $sel = "1"; ?>FJW Industries Lens 90mm f/1.0 } if ($loc == 'IT') { $sel = "1"; ?>FJW Industries Lens 90mm f/1.0 } if ($loc == 'AT') { $sel = "1"; ?>FJW Industries Lens 90mm f/1.0 } if ($loc == 'DE') { $sel = "1"; ?>FJW Industries Lens 90mm f/1.0 } if ($loc == 'BE') { $sel = "1"; ?>FJW Industries Lens 90mm f/1.0 } if ($loc == 'AU') { $sel = "1"; ?>FJW Industries Lens 90mm f/1.0 } if ($loc == 'FR' OR $loc == 'FX') { $sel = "1"; ?>FJW Industries Lens 90mm f/1.0 } if ($loc == 'NL') { $sel = "1"; ?>FJW Industries Lens 90mm f/1.0 } if ($loc == 'CA') { $sel = "1"; ?>FJW Industries Lens 90mm f/1.0 } if ($sel != '1') {?>FJW Industries Lens 90mm f/1.0 } ?>

2) Leica Leitz 90mm f/1.0 } if ($loc == 'ES') { $sel = "1"; ?>Leica Leitz 90mm f/1.0 } if ($loc == 'IT') { $sel = "1"; ?>Leica Leitz 90mm f/1.0 } if ($loc == 'AT') { $sel = "1"; ?>Leica Leitz 90mm f/1.0 } if ($loc == 'DE') { $sel = "1"; ?>Leica Leitz 90mm f/1.0 } if ($loc == 'BE') { $sel = "1"; ?>Leica Leitz 90mm f/1.0 } if ($loc == 'AU') { $sel = "1"; ?>Leica Leitz 90mm f/1.0 } if ($loc == 'FR' OR $loc == 'FX') { $sel = "1"; ?>Leica Leitz 90mm f/1.0 } if ($loc == 'NL') { $sel = "1"; ?>Leica Leitz 90mm f/1.0 } if ($loc == 'CA') { $sel = "1"; ?>Leica Leitz 90mm f/1.0 } if ($sel != '1') {?>Leica Leitz 90mm f/1.0 } ?>

3) Varo Optical Inc. High Speed Lens 90 mm f:1.0 } if ($loc == 'ES') { $sel = "1"; ?>Varo Optical Inc. High Speed Lens 90 mm f:1.0 } if ($loc == 'IT') { $sel = "1"; ?>Varo Optical Inc.

High Speed Lens 90 mm f:1.0 } if ($loc == 'FR' OR $loc == 'FX') { $sel = "1"; ?>Varo Optical Inc. High Speed Lens 90 mm f:1.0 } if ($loc == 'NL') { $sel = "1"; ?>Varo Optical Inc. High Speed Lens 90 mm f:1.0 } if ($loc == 'CA') { $sel = "1"; ?>Varo Optical Inc. High Speed Lens 90 mm f:1.0 } if ($sel != '1') {?>Varo Optical Inc. High Speed Lens 90 mm f:1.0 } ?>

4) Canon XI 90mm f/1.0 } if ($loc == 'ES') { $sel = "1"; ?>Canon XI 90mm f/1.0 } if ($loc == 'IT') { $sel = "1"; ?>Canon XI 90mm f/1.0 } if ($loc == 'AT') { $sel = "1"; ?>Canon XI 90mm f/1.0 } if ($loc == 'DE') { $sel = "1"; ?>Canon XI 90mm f/1.0 } if ($loc == 'BE') { $sel = "1"; ?>Canon XI 90mm f/1.0 } if ($loc == 'AU') { $sel = "1"; ?>Canon XI 90mm f/1.0 } if ($loc == 'FR' OR $loc == 'FX') { $sel = "1"; ?>Canon XI 90mm f/1.0 } if ($loc == 'NL') { $sel = "1"; ?>Canon XI 90mm f/1.0 } if ($loc == 'CA') { $sel = "1"; ?>Canon XI 90mm f/1.0 } if ($sel != '1') {?>Canon XI 90mm f/1.0 } ?> -> Images samples on flickr

I found image samples for the Canon lens only and I don’t know if you can use all of them on a MicroFourThirds camera. Let us know if you ever used one of those lenses on your camera!
Thanks!
