I've been captured by aliens and they keep making me buy things I already have. This time, an Asahi Pentax SV, 50mm super takumar, dedicated exposure meter and case.
Help needed. I'm reaching out people. Is it possible to have your ebay password erased from your memory or something?
It arrives tomorrow.

"I had to have it" sounds perfectly rational to me. But what do I know... Perhaps you need a G.A.S. mask? _________________

I must admit, this new syndrome I've developed has left me exGASperated. I've never thought of myself as a collector, and that the large box of gear I have is simply the product of someone who's had an interest in photography over a long period of time. 'Stuff' kind of accumulates I've always thought, but buying another SV is changing my mind on that. |

Like . It looks like the lens on yours is about centred. The one I have is more out than yours. I must admit, the photographs weren't the best and the seller didn't mention if anything actually worked, but having poked around inside mine a few times to keep it running, there's not a huge fear in acquiring one blind. Like yours, everything is there, well, apart from the flat sided triangular strap-lug rings, which I don't see made anymore. Fingers crossed.
Actually, to get those kind of lug rings, I'd probably need to buy another SV which still has them. Oh god... it's getting worse... |

There was one big surprise I wasn't expecting. I'd always thought, courtesy of the internet, that the f/2.0 50mm, which I already have, was simply an f/1.8 with an insert which governed it down to f/2.0. So I wasn't expecting, when I compared the two, to discover that the f/1.8 also has the same insert, but the front and rear elements are greater in diameter -
I can't tell if the glass elements are actually larger, or if the elements in the f/2.0 are being governed down by the rings. But I'll find out soon enough as there is some fungus to attend to in the f/1.8. Still, not what I expected from reading on websites (not MF Lenses I have to say).
Onward... |

Sounds similar to my case. I started with old manual lenses simply because I couldn't or wouldn't afford to buy new modern glass. I was never going to collect them, just try a few and use the ones that are not completely useless, that was my original plan. But the turning point in my "career" was when I realized I just wasn't any good at photography and probably never will be, so I decided I would become a "collector" instead. So now I have to support a growing family of old Minolta cameras and lenses plus some others. The main problem is that being a shit photographer is mostly free, but being a "collector" costs money. _________________ my flickr stream |

My interest in photography was rekindled when I realised you could buy adaptors for your old lenses and fit them on to a digital back. While hunting for a digital back, I ended up with a Panasonic GF1, I realised it was pretty affordable to add to the lenses I already had. I still don't have a detachable auto focus lens to my name yet. |

I have the version that goes past f/2.0, but I don't get a larger aperture as, when I click past '2', the blades drop behind a fixed aperture in the lens, making therefore no difference than when set to f/2.0.
I removed the fungus from the f/1.8 last night, but.. duh!, forgot to take the opportunity to compare the size of the glass elements in the two lenses. I'll have a look perhaps tonight if I get a chance. |

For someone who would 'do without' for periods in his younger days in order to buy a decent film camera, the value of them today needs a constant suspension of belief.
SV without lens. Stuck shutter curtain, but otherwise complete. £3.20 plus postage.
There's a couple of things I want to attend to with my others, but it requires delving into the mechanisms more than I would normally. So I've bought this one to strip down and familiarise myself first.
Crazy times. |

I had time to take the two lenses apart this morning and can confirm that there is no difference in the diameter of the glass elements between the f/1.8 and f/2.0. What makes the f/2.0 an f/2.0 and not an f/1.8, is deeper locking rings and an insert that prevents the aperture being smaller than f/2.0 at the diaphragm. Otherwise it is the same lens.
You kindly helped me a little on the variations of the 50mm super takumar, so in turn I hope this adds a little to your own knowledge.
At f/1.8 on 1.8 lens. One click past f/2.0 on 2.0 lens -
I appear to have spent a bit of time proving what websites already confirm! In my defence, critical thinking has been part of how I've earned a living, but this time it sent me off on a wild goose chase. My mistake was in initially thinking I saw an insert in the f/1.8 lens, like there is in the f/2.0 and it set me off questioning everything I'd ever read on the subject. There isn't one. |
