Canon MP-E 65mm f/2.8 1x-5x Macro Photo Lens

[colinbm]

I have bought a Canon MP-E 65mm f/2.8 1x-5x Macro Photo Lens & it works beautifully on my Sigma fp with a Canon EF - L mount adapter.
It is a strange lens in that it has no focus ring, but the Aperture is automatic.
To focus on the subject I have set-up a macro rail, which allows the camera or subject to be moved into focus.
At 1:1 the DOF is 3mm max, so focus stacking is used for deeper subjects.
Did I say it is a nice lens ?

Here I have used one of my pet fluorescent rocks from Puttapa Zinc Mine, in South Australia, To show it full size in the cameras frame in visible light, UVA365nm light & UVC250nm  light, to capture the visible fluorescence, ie UVIVF. The light sources are filtered for their UV band & the camera is an unconverted Sigma fp.

Visible light.....

 

UVA 365nm light induced visible fluorescence....

 

UVC 250nm light induced visible fluorescence....

The UVC version is brilliant! Yes the MP 65 is a great ens, though does need some practice!

Yes a fun lens. But doesn't transmit much UV.

Best for fluorescence. 

Great fluorescence images Colin.

I love this lens too. It perfectly closes the gap between classic macros and the microscope. And at a very high level!
Have fun with it, Colin :)

Very cool looking Fluorescence. Does that lens not work with a helicoid?

It is a very special lens for 1x - 5x only.

It is not possible to use/abuse for less magnification.

It has a front lens group and a rear lens group that are separating when increasing the magnification.

At such big magnifications focussing is best done by moving the motif or camera+lens.

However it can be used with either a Metabones speed booster or a 1.4x telephoto adapter on a m43rds camera.

Nice photos!

Thanks everyone for looking & your comments.

Fluorescence from UVC is awesome.

That's a great lens Colin, and wonderful fluorescence images. The 254nm one is amazing.

Thanks Ming
@JMC Thanks, this is with a 250nm LED light.

Oh, right, very nice for LED lighting at 250nm then.

Sorry Jonathan but I had a senior moment & the LED light is 255nm.

I would really like to have a powerful 253.7nm LED :-)

No worries. Still very impressive.

LEDs have a medium-sized bandwidth, so even if the peak was at 253.7nm, it would probably be 240-270nm in practice. And the peak moves as it heats up, so the “0.7” would truly be meaningless.

Well then just 250 or 255. But having 3W radiant output or more... not those available now.
