Trying a Photar f4.5 80mm Macro

I noted the presence of this lens on Ebay for quite a long time. I believe I was one of 12 watching. Offers were invited and I waited for it to be relisted before submitting and offer. I expected a counter offer but mine was accepted.

Before buying, I tried to find information about the lens and its performance but found nothing useful. Based on having a 50mm Photar with superb performance, I went ahead with the purchase.

I used the same triple helicoid extension that I used for my Tominon. On m4/3 (17.5mm sensor) one helicoid fully opened up gave FOV 7mm wide, two gave 4.5mm and three gave 4mm. Extensions from the camera flange were 320, 360 and 415mm, respectively (add 20mm for distance from the sensor).

The setup was hand-held and illumination via triple TTL RC flash.

I chose f8 and f11 to test. Only the images sets at 4.5mm & 4mm FOV delivered one worth using, such that here the (uncropped) ones with the subject a little large were FOV 4mm.

A great deal of what a lens will do depends on how it is used. This was my first attempt. It was in bright sunlight, which illuminates the subject perfectly but it also is very contrasty, making seeing the subject in the viewfinder a bit difficult, such that using the tiny DOF can be tricky to judge. So, not many images were acceptable and none should be taken as a showing the best that the lens can do.

Whether by intention or sheer luck, some of the images provided stereo pairs, presented as crosseye versions.

The subject is the fruiting bodied of the slime mould Stemonitopsis typdoides. They are not necessarily in line with their stalks or straight cylinders, so there DOF issues.

Olympus EM-1, Leitz Wetzlar Photar, lots of extension, 1:4.5/80, triple TTL flash.




The body is willing but the mind is weak.
