Mamiya Sekor 4.5/105-210 ULD - the birds and the bees

Oldhand

Forgive the subject matter, but our magnolia has just produced its first ever flowers, and a yellow faced honey-eater has built a nest by our front door.
OK the bees didn't hang about for the picture but the bird stayed.
Here ya go

Beautiful series. I especially like the bird preening in the second to last image.

Nice photos! The CA is well controlled thanks to ULD glass.

Thanks Calvin and JJB.
This is a seriously good lens and one that I hummed and harrred about for months because of its strange zoom range and slow maximum aperture (4.5)
Saw this one very cheap and decided to try it out.
The ULD glass certainly makes a difference and the colour and definition are pure Mamiya - very chuffed am I.

Splendid shots. Very clear and vivid. Seems good for birds and macro.

Thank you Pancolart.
I took these images to help build up a small profile for this lens.
There is almost nothing about it on the web that I can find and it is often available cheaply.
Here are some extra images.
Most of these and the previous are taken at full aperture.

Wonderful pics of that bird! Shocked

Seems to be a very good performer. Btw how to shot birds like this?

Finally, a picture of the lens itself.
Even though it is a lens designed for Mamiya 645, it is still around the same size as a Vivitar zoom of similar range and vintage.

A shower of rain and everything in the garden looks different.

That's a great lens Tom, there are zoom lenses out there that surprise us - that's one of them.

I just have checked the earlier and much larger "non-ULD" version of the Mamiya Sekor C 4.5/105-210mm, comparing it with the Canon nFD 4/80-200mm L at f=105mm and at f=200 (210)mm on 24 MP FF. Even the the "non-ULD" is as good if not better than then Canon L glass, both regarding resolution as well as lateral CAs (virtually non-extistent at f=210mm).

I'm pretty sure the "non-ULD" version of the Sekor C 4.5/105-210mm has ULD glass as well - as it must be the case with the Sekor C 5.6/300mm: The 5.6/300mm "non-ULD" and the later "ULD" version have exactly the same optical properties (i. e. lack of lateral CAs).
