Easy mistake to make as Minnies changed a lot. I almost always have to refer to the Rokkor Files as the chops and changes are quite confusing late on in the SRTs life.

From what I saw with this and thinking about it I suspect that the sequence of events was......fungal and oil contamination weaked and probably ate whatever coatings may have been present. The acetone destroyed the fungus but exposed either an oil base or the remains of the coating. When the IPA hit it somehow affected the remmains of the coating or the oil residue causing the cloudy look, the cloud was inpenetrable by the way looked like an opaque piece of glass or frosted glass. The second stronger acetone bath removed some of the worst drek and fungal stuff that was left and the long IPA bath broke up the oil, though there was no residue after the second IPA bath. I think pethaps the second IPA bath weakened whatever was causing the cloudiness and the strong washing up liquid just allowed it to float off. Thats all just guesswork....in truth I have no idea what was going on as I have never seen lens glass react like this.

I am really more au fait with astro stuff and generally use pure soap flakes to clean mirrors and lenses. Talking to a chemistry boff today his view was that commercial soap powder suitably mixed into warm water would be the best at killing off crud on a lens as it contains anti fungal, oxidisers and is quite kind and unlikely to eat stuff like coatings.

This one has been a complete bitch of a job so far. At the rate its going I am going to have to take this puppy down to its constituent molecules.

I should have taken pics for the back from the dead thread but while the digital was charging up I made a start and got so obsessed by the time I remembered to take some pics there was not much point.

Its an ancient 50mm Takumar M42 thread of course acquired for not much in shocking condition. Looked like it had been left in a ditch for 10 years. I have used a acetone before in a dilute solution to remove complete horrors including suoer bad fungal drek that was actually black in the rear element of this lens. Its always a method of last resort and yes I know it will strip paint, coatings, almost anything even in very dilute form which is why I never use it near a painted surface and prefer not to use it all. Given by the time I got to using the acetone the prognosis was terminal I thought it was worth a try. On anything plastic I would never use acetone or IPA as it will frost the surface super fast.

Want to know something really weird that makes abolsutely no sense at all ? I left the lens in IPA for 6 hours took it out and it had improved somewhat, another wipe with a microfibre cloth started to remove the frosted glass looking effect. And started shifting the frosted glass effect around on the lens almost like oil but like nothing I have ever seen, moved around like oil but looked more like fungal etching and although its edge would move and or occasionally show clear the central portion never did !!! So I gave the lens a warm bath in a strong washing up liquid solution, took the lens out after 10 minutes, ran it under a tap and OMG its come out sparkling clean apart from some small fungus etching at the extreme edge in one place....at least its assumed to be fungal etching because so far nothing has been what it seemed with this piece of glass.

From where I was yesterday with a lens that started out hazy with fungal spores and threads, through to the lens looking badly scratched and finally looking like it had been rubbed down on an emery cloth the transformation is amazing. The extreme edge now has what looks like fungal etching but I have seen so much weirdness with this that I am going to give it a shot of peroxide as soon as I can get some and see what happens, while waiting for the peroxide I am going to try the old pure hand cream trick and see if that makes any difference.

I have done quite a bit lens cleaning and never seen anything like this. My best guess is some kind of chemical reaction between the compounds used, the fungus ( which I am now thinking was more pervasive than it seemed on initial inspection ) and perhaps the coatings. Whatever it was its gone away and the lens now shows clear.

I dont know that thats true with the SRT......I have had 5 SRT 101s to bits,admittedly not a total strip but I didnt see any plastic gears at all. The later models like the cheapie SRT 100b they made for Sears which were stripped down versions of the 101 rather like the K1000 was from the KM/KX might have replaced bits with plastic.

If you really want metal and tank like construction check out the Canon FTb, it weighs a ton and I would serioulsy doubt there is any plastic in it at all.

I am trying to bring annold lens back from the dead but have hit something weird I have never seen before.

Front element had fungal growth behind it. It wasnt super bad and I had imagined a hit of acetone would clean it off no problems. So I gave the lens a quick bath in a dilute acetone solution and hola off came the fungus. The lens also showed hazing which I had taken to be general drek build up and vapourised oil as the diaphragm was oiled up and the focus was cranky too.

Heres whats weird, after the acetone wash I gave the lens a wipe down with some IPA and scratches started appearing, at least they looked like scratches. I was weirded out by this as the lens was cleaned with a microfibre cloth. So I just assumed maybe some contamination. Cleaned the lens again with IPA and broke out a new cloth. After the second round the lens was very cloudy and now looked like it had been rubbed down with emery cloth. It made no sense to me at all. I cant see why successive IPA should make the lens go milky and more worryingly start to look scratched.

My best guess was that somehow the coating was the problem and the scratches were in fact linked in some way. So I decided to take a gamble and give the lens a 6 hour bath in a strong acetone solution. Now the scratches or at least what looked like scratches have vanished but the lens now exhibits super bad haze. Interestingly the acetone bath showed an oil like residue on the surface which leads me to think the coatings were dissolved by the acetone or else the hazing was some kind of contaminant thats now been removed but the contaminant has damaged the glass.

My best guess is that something in the cleaning program has caused the coatings to go weird but I cant imagine what that is. The lens was badly hazy when I got it but nothing like as bad as its now looking and I am at a complete loss as to what the issue may be. I am considering a strong peroxide bath but wondering if I am wasting my time.

I am wondering if the original hazing was down to some kind of coating issue, rather like the Tamron BBAR teleconvertor can suffer from which was down to the factory coatings being faulty causing them to go cloudy over time.

Any ideas would be welcome.

Yes I had seen the other items, frankly the prices are completely bonkers.

I think he is either on drugs or mahbe acting as money launderer for the cartels he also has a Canon T50 he wants 382 for :)

I bought a Tamron135mm a few months back and it was just like new, in a box, with instructions, dealer display tags, waranty card, silica gel bag and case. Outer box was near mint and inside it was hard to believe it had ever been opened paid peanuts for it on eBay.

Lord Lucan.....yep another UK bod here and I cant ever remember seeing a standard set up with anything other than a 1.7 or 1.8 depending on brand. Must have been something ro domwith our dismal weather.

Check this out......
A Minolta 50mm f1.7 for a mere 231. Once you take it out the box you are down 200.

I bought one in as new condition recently for 31... ok I didnt get a cardboard box and polythene bag with mine but its indistinguishable from a brand new lens.
I have seen a vew of these old new stock things and I cant see the attraction. The lens could still suffer ills sat in a box unless its been kept warm and dry for its entire life and even then the lube could have dried out from lack of use.

Well I suppose I could if I carted my Skymax Pro scope around but its a tad on the heavy side. Its a 7 Maksutov telescope with a 2700mm focal length and f15 to boot. Only problem is it weighs a few pounds :) and needs a monster mount to hold on to it. I must get round to taking some shots with it though as I do have the adaptors to hook it to one of my OM1s. Hmmmmmm thats got me thinking :) Outside of astro....fast film, lots of seagulls roost near me. Hmmmmmm, :) thanks thats a project for me to mess with.

And heres my beloved - Minolta Rokkor 58mm f1.4 PF - shot on a. Minolta SRT101. Again its just scanned from a print and not an art shot- only a test roll to check out the SRTs meter. The lens had terrible haze, fungus and dust plus a stuck/sticky focus ring due to crud build up. I did this one myself as these lenses are not terribly tough to work on unlike the Nikkors.

This will get me drummed out the Pentax magic circle for sure but these are my two faves back from the dead......

Nikon 50mm f1.4 - used to be a favourite lens of mine. This one had super bad fungus round the rear edge of the rearmost element. It was so bad I had to get it done professionally. Her focus mech was also rather gummy and has now been cleaned and relubed.The shot of the River Wey with a reconditioned old mill block (now flats) was taken with this after refurb.

This wasn't an art shot just one from a test role to check out the Nikon F.

I don't like working on most lenses and especially not Nikkors.

I have a Made in Japan one.....

It has Asahi on prism housing
No blanking plate or moulding where the KX battery test would be. Its just plain metal.
Metal top and bottom plates
Metal shutter speed dial
Asahi Opt. Co. engraved under film advance lever
Small silver sticker on base plate marked Japan

Came with an M series 50 f2.0

People seem to have lost their minds with the prices of these and of late I have been sorely tempted to sell it and cash in on the madness and buy myself another Minolta but then I would have to deal with angry Pentaxians with burning torches storming my castle :)

Id say just skip the K1000 and get a KX, it wont be as expensive and its much nicer to shoot with plus it has a better meter, self timer, DOF, mirror lock up and PC connect for flash cords for non hot shoe flashes.

I cant say from actual experience but I have done a lot of research and reading and the early FEs are reported as prone to electronic failure of varying degrees. It could be something dead simple like corrosion on a contact, resistor or switch gear somewhere or it could be something very serious. The FGs were rated as very unreliable electronically as well. Best bet would be to have a tech look at it as it could be simple. Some of the early minoltas suffer various electro ills and many are down to pretty simple fixes IF you know what to look for.

In the main I steer clear of electronics based cameras for just this reason.

Latest and (hopefully) last is a Minolta XD7. She looked very shabby when I bought her from eBay mainly for the older MC lens she was wearing. leatherette had disintegrated (common problems with early models XDs), shutter speed indicator in viewfinders non working (lying eBayer) and the air piston that slows the mirror down was clogged so she would stutter when taking a pic (common problem with XDs) and naturally all the light seals and mirror damper were perished and she was absolutely filthy- though her finish, ap[art from the leatherette was near mint - all that crud on her had probably protected the unique black finish these had.

On the upside I only paid 23 and got a near mint Rokkor MC1.7 which was the whole point of the buy anyway but I thought I would see what could be done to salvage the camera as the electronics were all running. The MC lens was nicked to allow me to get a full original Minolta SRT101.

So she had a new set of leatherette, replaced the non original film rewind spool, replaced all the seals and mirror bumper, thorough external clean and then she was sent off tom favourite camera tech to have the VF shutter speed indicator fixed, the air piston cleaning and an internal clean including the focus screen and a check that her speeds were running correctly. Voila- for an investment of maybe 80 plus the 23 to get her I now have a near mint beautiful black Minolta XD7 (2nd production batch) - serviced and ready to rock and roll.

Here she is with the correct kit lens she would have been sold with.

Weirdly I had some old Smartmedia cards and Cardflash cards from the early fays of digital, all running and tested. Put them on the bay for .99p in case anyone wanted them as collectable plus some old digitals cant work with new high capacity cards and it turned into a bidding frenzy. Cant remember what they sold for but its was like 10 a card for the SMs.

Outside of Pentax and for small size you could consider a Minolta XD, fabulous small camera with aperture and shutter priority, small size. Be wary the electronics in it can be rogue but there are good ones out there. Aim for a late model if at all possible.

Nikon FM and FE are apt to be pricey.

OM1 is nice and compact, reliable and mostly mechanical. Older ones can suffer meter failure and very old ones can suffer prism desilvering if no one has cleaned the cruddy foam out of them. Used to be my personal favourite but its been pushed out by the Minolta XD7.

Canon I dont much like on the whole. Had an EOS when it came out, hated the feel of it and it was a horror for faults, AE1 is a bit too plastic fantastic for my taste and handles like a dog especially if you want smooth DOF control. The only Canon I have recently grown to love is the FTb, very smooth, built like a tank and all mechanical but its a beast of a camera in size and weight.

Pentax KX, about the same as the Canon FTb but more refined. Still a beast with tank like construction.

Price may be different as all these seem to vary country to country.

I think you need to decide what it is you actually want to use it for...is it a trip down memory lane, a passion for old tin, a devotion to film, curiosity, art etc and how much do you want to spend. WARNING a passion for old cameras can seriously damage your wealth. I started off picking up a KX in a charity shop now I have a whole collection of the damn things and never get to spend anytime taking photos as I am too busy fixing them and too poor to afford film as I have to spend every penny on restoration :)

What were the preferred film types in 1983 for a film shoot at night?

I was semi pro back then and for night work woould most probably have used HP5 pushed to 800 or beyond depending what the subject was. Pushed it up to 3200 once and it worked ok for press type work. I generally kept a pair of bodies locked and loaded in my tote bag as I never knew what I might need as a freelancer but mostly selling to the press...car accidents, train derailments, court appearances etc my other stuff was the dreaded weddings, bar mitzvahs and the like mixed in with some product photography.

Big league fashion would have more than likley used Hasselblad or Bronica back then. Some of the big league 1960s guys used 35mm for some stuff so might have shot with Nikon, Olympus et al.

No idea what a landscaper would have used for pro gear. Some of those guys were using monster plate cameras back then. I am guessing they would have gone Bronica or Hasselblad though.

Cant say on Mamiya.....never saw one being used by a pro but pros are quite often super specialised and sometimes quixotic in their choices :)

K mount starter set advice
Posted By Astro-Baby

I would go with;

Wide ......either a 35mm or 28mm depending on preference. I prefer 35mm but I also have a 24mm whcih gets not much use.

Standard......50mm I always tend to stay with whatever the canera was sold with. 1.7 is fine and keeps the cost down. I have some cameras with 1.4s, 1.2 is usually insanely priced.

Telephoto.....135mm should be good for most. I get little use out of 200 and 300 lenses.

Zoom......I always like to have a short zoom something like 35 to 70 for walkaround when I am not carrying a gadget bag. Not essential but in the world of old glass try to keep the zoom ratio low as old glass was not good at coping with massive zoom ratios.

Brand, I always prefef the 50mm standard to be whatever the cameras was originally supplied with. The others could be anything. As I have a wide range of bodies I use Tamron for the Adaptall capability but thats just because of the different mounts I have. If I were sticking with K mount Id be flexible and try for OEM but maybe settle for third parties products.
