Do it! It's a relatively simple job, once you have it back together anyway! My aperture blades collapsed last time I took my rokkor apart for cleaning, took a while to it back together but I'd be able to do it much quicker next time
i have no issue taking it apart but i dont know how to get the aperture mechanism apart.

somewhere i think i posted directions on this, will look for it. the rokkor 58/1.2 is a mercifully easy lens to disassemble, though putting the actual blades back in the iris is always a pain.
I just did my 85/1.7 top to bottom since the blades would not go past f4 and were getting worse, and focusing was an effort. It wasn't too hard to do the blades, getting the blades back together wasn't too hard.
There was a disk with holes at the bottom, the blades have a stud that goes in the hole, stack the blades moving to the next hole, the last 2 are the hardest to seat since they go under the first ones, just hold them down so they don't pop out, space out the upper studs, that will make it easier to set the cup with holes into position with the studs in the holes, invert the sandwich onto a tube(or your hand), then lower the lens slowly over the sandwich till it bottoms out, keep pressure on it till you flip the lens and set it down, then it's just a matter of reversing the disassembly.
My lens works like new so, I'm a happy camper now.

I bet you are. That's a damned good lens! One of the best, IMO. Worth the effort!
The lens is the Rokkor-X 50mm f/1.7. Very inexpensive but a great alternative to larger and more expensive lenses.
The color balance looks quite off. It was weird to begin with (because of all the different kinds of light sources in the bar) and in the web browser it's a lot worse.

This is an underrated lens that often goes on the camera when I'm going out. Works great for portraits.

What colour space are you using? I always make sure to output to sRGB for web. Some browsers support alternative colour space these days, but probably still best to stick with sRGB since it is supported by everyone's browser.
On another note; do they teach American in Swedish schools, or English?
cogitech, I now realize it's Adobe RGB. I usually use it for printing, so that's where I went wrong I suppose.
Off topic:
When I went to school, focus was primarily on British English, but I believe they now teach a little bit of both. My own English is at this point some pidgin blend of mix of Australian, US and British English (after having spent years working with people from all over the world, most of which do not speak English as their primary language).

I can confirm your experience with this lens.It takes the second place after MC Rokkor PG50/1.4 in my personal ranking.This refers to both 55mm Rokkor X (MD) and 49mm series.

Excellent series of images Brad!
Really like the interaction and comp of the 3rd shot.
Makes me really miss my dog.
I liked the SciFi movie with this title.
