Further to my previous posts  Nr's. 57 and 58 in this thread:  Yesterday, I visited the same local nature reserve pond armed with SL 601, vintage Novoflex Noflexar 600mm f8 and Leitz APO 2x extender to photograph dragonflies and birds

This was the first time I'd tried the 600mm Noflexar in 'close-up' mode i.e. using the Novoflex mount built-in bellows to reduce the minimum focus distance. Using the 2x extender doubles the focal length to 1200mm and reduces the max aperture to f16. The lens diaphragm was stopped down by half a stop thus the resultant taking aperture was approx. f19

Mature Male Emperor Dragonfly      SL / Novoflex 600mm & Leitz APO 2x extender 

 

 

Note the specimen's torn wings … but it can still fly well and defend its territory. The specimen was approx 4m from the camera and the images have been slightly cropped. 

 

I'm pleased with the lens close-focus performance - especially as it cost just £69 (head and tubes only … not the full mount) from Ffordes 4 years ago. I've only recently acquired the rear Novoflex bellows mount so was not able to explore the lens' c/u ability previously. The lens head was actually manufactured by Leitz for Novoflex … and Agfa made and assembled the Novoflex mount including the rear bellows.

 

One day Leica will probably introduce an SL 560mm lens with matching extenders - but until they do, and given the fact that there are no third party AF lenses for the SL, I'm quite happy to continue using manual focus legacy lenses. 

 

 

 

Best wishes

great photos, such clear and sharp images from your rocket launcher, well done. what speed can you use considering the aperture size, how do you get it so still, do you need a remote shutter release

The Jobu Design gimbal as illustrated in #63 enables perfect balance when the lens / camera is set up at the C.O.G. and very stable operation - thus no DA or remote release required. Perching dragonflies don't move (apart from their perches blowing in the wind) so ISO is selected to enable shutter speed of c. 1/320 to 1/640 or faster … in this case ISO 1600 and the camera selected 1/640 to match the f19 aperture of the 1200mm lens. I was seated in a chair with my left hand 'squeeze focusing' the lens and the right hand gently pressing the shutter release. 'Squeeze focus' is very different to conventional helicoid lens focus and enables more accurate focusing with the 1200mm lens; focus can also be achieved via the bellows. The 'squeeze focus' mechanism comprises spring loaded tubes and was lubricated with trombone slide oil for efficient 'fine focus' movement. Also managed some dragonflies in flight photos using the same set-up. The SL's clear viewfinder and magnified live view helps with focusing too. Most modern digital cameras have good high ISO capability thus have no hesitation in using ISO 1600 or 3200 with the SL.

Female Emperor Dragonfly in flight 

 

Emperor Dragonflies are the only UK/European anisoptera which exhibit a 'curved' abdomen whilst in flight … thus easy to identify 

 

SL/ Noflexar 600mm with Leitz APO 2x extender … thus 1200mm;  ISO 1600, 1/640, f19 … manual pre-focus from approx 4m distance   'close focus' (for a 1200mm lens) achieved via the Novoflex mount's built-in bellows

 

If only Leica would / could offer e.g. an SL 560mm lens with a dedicated SL 2x extender, this type of image would be a lot easier to achieve i.e. with a higher shutter speed and lower ISO
