I don't know what "Lens Coat" is, but that sure looks like a plastic plant pot -- not a bad idea. They are plastic, and easy to get. Just re-pot the plant, and clean it out. Then cut a hole in the bottom to fit your lens. I've got a ton of those pots!

To my eyes, it looks more like a fabric. Nice. Thanks, Basil for that report.

The extra reach is nice but I'm not sure that I can't get a sharper image from the Minolta, cropped to equal the 700mm field of view.

I think if I were to consider a longer mirror, I'd try 1000mm Rubinar or MTO. The focusing gets harder and IBIS a necessity.


Thanks for your thoughts Mike! No I have never had the Minolta; as Joe said the Sony is just a rebadged Minolta probably. I agree, using the Sony 500 in APC-mode on my a7r4 will make an excellent, and lightweight AF 750 cat! I would like to use a Rokkor 800/1000 though ... The Nikon 800 gets great reviews; on eBay most of these come from Japan and the price for the Rokkor and the Nikkor is about the same.

I've used sheets of fairly dense black craft foam to extend hoods on lenses and telescopes .
Just wrap it round the lens and use a thick elastic band to hold it on and slide it forward so it's got a good overhang .

This thread has renewed my interest in this lens. I have to get out and play with it some more.



Thanks for your thoughts Basil! Would love to see the results of your playing with this beauty!

Leo: This is something I do not understand - using the camera in APS-C mode. How can that be any better than FF and cropping?

I'm guessing that you already know that buying lenses from Japan (which I have done) includes a greater risk of fungus. From what I've seen, it appears they have a climate that is ideal for growing fungus.

The Lens Coat travel hood is a thick cordura fabric with rigid plastic internal ribs. It wraps around the lens and closes with Velcro. It is much better than the plastic bowl I used at first. I also tried a flower pot as well as foam craft paper. I bought the lens coat hood for my Minolta 400/4.5 which has a hood that tends to fall off at the most inappropriate times. It's a bonus that it fits the Rokkor, as well as a few other long lenses I have. It wasn't cheap, but it was worth it for the frustration it saves with the 400's hood. Click the green text above for a direct link to the product page.


I would also love to have a go with the 1000 or 1600. Since I have yet to win the lottery, those dreams will simply have to wait.

We all have our limits. That's true. That's why I like the flower pot idea!

And good luck finding a 1000mm or 1600mm. The 1000mm will be especially hard to find, and I suspect collectors will drive the price through the roof. I just noticed that one of the original Minolta Rokkor 800mm CATS recently sold on EBAY for about $1,100. It's only "claim to fame" is that it is marked as 80CM, not 800MM -- like all of Minolta's early lenses over 200mm.

I'll stick with my much less expensive Honeywell 1250mm f10.5. Despite being a slightly-stripped Celestron C5, if focuses down to 16 feet with a very fine focusing dial on the rear.

Not much of a claim to fame. It just means it the first version. From a post a few years back:

The 80cm came out in 1972, just before the Rokkor-X line appeared -- that's when the 80cm was changed to 800mm and the "-X" was added (in the US market). So the 80cm version is definitely harder to find.

It makes composition easier, that's all.

If I buy from Japan, which is seldom, I always buy from excellent sellers; and only if they indicate the lens has no fungus, and have a good return procedure.
You're right, Japan is a dangerous country for lenses!

Thanks for the link! Did you buy the large or the small hood?

Leo,

I bought the large. It is versatile enough to use on a wide variety of my long lenses. I have even added it to the slide-out hood of my 600/4 in very bright conditions. It folds flat so it fits in a camera backpack quite easily.
