Why are these so cheap?



I can only use this on my Nikon D300 at present, but it would be able to be used on other types of camera I am sure.
With a glassless adapter, it cannot focus to infinity.
Its normal minimum focus range is 4.5metres. With the adapter, this shrinks to 3 metres.
Maximum focus range with adapter is 10 metres on the Nikon.
This range is very useful for me and fills the viewfinder nicely.
Here is a sample image:
-wide open at f/5.6


Compare to Nikkor AI 50mm f/2 exposed at f11:

Yes.
It was up for seven days, and I was the only bidder.
OK it's not a fast lens, but it sure is sharp.
Cheers

Definitely not fast, but your comparison against the Nikkor 50mm f2 shows almost identical results. I recently put my Nikkor against my Minolta MD Macro Zoom and the Nikkor won hands down. Sharper and more importantly contrast was strong. The Minolta zoom looked flat in comparison.

This would be either Tokina or Komine made.

Thanks for that.
I was unaware that Minolta lenses were made by other parties.
Always imagined that Minolta made their own for some reason.
Cheers
OH

Why so cheap? I guess it was you who won this for $30 recently.

I think the reason it's cheap is that Rokkor dont have a magic name like Nikkor, Super Takumar, Hexanon et al. Also wides tend to be more expensive as thats mainly what people want.

regards quality its not too hard to make a 300mm prime lens, its a very simple formulation, so almost every decent brand of 300mm is capable of giving great results compared to sub 135's.

The particular model you have was made and badged for the US only between 1975 - 1977

I bet its heavy, a couple of pounds easily.

Enjoy.

... by Minolta? or as has been suggested, by Komine or Tokina?

Heavy - not so much. 800grams or 1.7637 pounds.
Long though, yet easy to hold.
Thanks
OH

Afaik, minolta made it own lenses, except those made with leica.

It's difficult to beleave that there are some people who don't know that minolta did excelent lenses, like the 1,2/58, 1,4/50, both mc version, almost all the 135 too, the 1,7/85, the 1,8/35, 2/28, the last version of the 1,7/50, the 20 mm one and the 2,8/24.

****Why are these so cheap?****

Well the lens would be ok for sunny Australia, but for the UK without a tripod and say f8, would need a fast shutter speed/high ISO combo to be of much use......so that lets me out as a film user as my favourite films are 100 and 200 ISO. Sad

i have this lens and it's very good performer. and it's lightest 300mm lens i own.
why cheap? probably because of f5.6

The 'X' was a designation for lenses destined for the North American market and like the MD lenses had supposedly more advanced coatings

I found some "X" rokkors with the coated identical to not "X" ones.

Almost all collectors think that the "X" lenses for US are market branded, no more than this. The better lenses? Perhaps for japanese market, not for US one

Ohh....my english is so bad, man.

For example, my mc 2,5/100 has the same -orcontrast very similar- coating as my mc "X"lenses lens. The coating in minolta lenses changed with the time (dos i'm not speacking about the celtic ones) by the time. Contemporary lenses the similar coating
