Nikkor 300mm f/4.5 H non-AI

Nikkor 300mm f/4.5 H non-AI (non-AI 1969-'77, AI '77-81, AI-S '81-94)
This sample circa '69.

Filter size: 72mm
Close focus: 13 feet/4 meters
Aperture range: f/4.5 - f/32
Aperture blades: 6
Depth of field scale for f/11, f/22, IR index.
Design: 6 elements in 5 groups

Comments: Note there is an earlier 5-element version which looks the same, just with a P instead of an H. I was pleasantly surprised by this lens - it seems like a pretty solid performer, at least for black and white use. The lens is pretty big and hefty, and my sample is rather beat-up externally.

Here are the two 300mm lenses side by side:

The Nippon Kogaku and Nikon versions pretty much look the same.

Oddly this lens was never made in a C version.

The K verion and AI only differ cosmetically. The last AI-S version does focus a little closer, to 3.5 meters (but you should get the ED-IF version which focuses to 2.5 meters). It seem strange the design lasted so long, and that it was never upgraded to 7 aperture blades.

Ken Rockwell's review of the similar Canon EX Auto

Comments: Interesting camera. Well built. This is my first experience with the Canon QL quick load feature, which seems to work okay but I don't like. One just pulls out the leader the appropriate length and closes the back without slotting it into the take-up reel.  There are two very unusual things about this camera. First, you adjust the aperture via the knob under the rewind knob (there's a read-out in the finder). The second, and more distressing, is that the viewfinder image is always sharp. You can't see the depth-of-field the lens sees at all, which makes focusing weird and defeats the purpose of an SLR IMHO, which is WYSIWYG. Have I used enough acronyms yet?

Here's a (bad) picture of the camera with the 95mm f/3.5 mounted. In front are the 35mm f/3.5 and 50mm f/1.8.

Filter size: 48mm (I think? unlabeled
Close focus distance: 1.5 feet/0.45 meters.
Aperture range: f/1.8 - f/16
Depth of field scale for f/4, f/8 - f/16, IR mark.
Made in: Japan

I like this lens!  It is quite sharp and has very nice tonality.  I'm quite impressed since the front lens elements are interchangeable.  The rear 3 elements are fixed, and the front elements are interchangeable.  You can also find 35mm, 95mm, 125mm f/3.5 Canon EX lenses. I am curious if they perform as well at the 50mm.
