Bought a cheap spanner off Amazon to adjust infinity focus on a vintage Nikon lens. The tips bent after two turns. Slipped and gouged the helicoid threads. Now the lens is toast. Anyone got a source for real hardened steel spanners?
I spent years fixing old screw-mount lenses where the aperture ring is directly coupled to the blades, no levers or springs in between. Last month I tried adjusting a modern electronic aperture assembly on a Canon EF lens and holy cow, it took me three tries just to get the ribbon cable seated right. Has anyone else found that older mechanical designs are actually faster to work on despite being more fiddly?
I was stuck on a Pentax Spotmatic that had the slow speeds all gummed up. I figured I could just eyeball it like always and call it good. But the 1/15th and 1/8th were way off again after a day of testing. So I caved and ordered one of those cheap digital shutter timers from Aliexpress for like 40 bucks. It showed up 22 days later in a beat up bubble mailer. I spent about an hour that first night learning how to use the thing. I guess I'm just stubborn and thought my ear was good enough for years. Has anyone else fought with timing lenses by feel only to finally give in and buy a proper tester?
I put a vintage 1930s Heliar on a Speed Graphic for years, and the soft look was perfect for portraits. Last month I switched to a sharp modern Zeiss thinking it would be better, but now every face looks too clinical and flat. Anyone else gone back to older glass after getting burned by the new stuff?
I had a Ricoh TLS 401 on the bench last Tuesday, cleaning the shutter assembly, and one of those tiny little curtain springs just went flying. I spent a good 45 minutes on my hands and knees with a flashlight trying to find it in the carpet. Ended up having to order a replacement spring from a parts donor camera I bought off eBay for $25. Has anyone else dealt with those finicky spring-loaded shutters on old Ricoh SLRs? It really tests your patience.
Honestly it was just a tiny bit of corrosion on the contact spring inside the button assembly, took me 3 days of disassembling and cleaning before I spotted it. Anyone else run into something that simple that took forever to figure out?
The brass just glides like butter even after 70 years, while the newer nylon stuff I had to sand down twice and it still caught on reassembly - has anyone else gone back to older parts just to get that feel back?
I was helping a friend fix a vintage Pentax lens last weekend in his garage. He wanted to separate a stuck helical group using a simple hair dryer. I was skeptical because I thought the heat wouldn't be strong enough or might warp something. We gave it a try anyway after about 15 minutes of warming it up. The element popped free with zero damage, and I was honestly surprised. Has anyone else had good luck using low heat methods for stubborn lens parts, or do you usually stick with solvents?
I had been struggling with fungus and haze on old glass for years, using q-tips and solution by hand. Finally broke down and bought a decent ultrasonic unit. My first job was a 50mm f/1.4 from the 70s that looked like a swamp. Ran it through three 5-minute cycles with a good surfactant and the elements came out spotless. Cost me $300 but it saved me maybe 6 hours of scrubbing on that one lens alone. Has anyone else found these things actually cause damage to certain coatings if you run them too long? I keep hearing mixed opinions.
I picked up this Yashica-Mat from a guy in Austin last Saturday for $15. The shutter blades were frozen solid, probably from old lube turning into glue. I see folks online jump straight to using lighter fluid or acetone on these old leaf shutters, but that's how you strip the coating off the blades. I spent 3 hours carefully warming it with a hairdryer and using tiny drops of naptha, and it freed up without any damage. Anyone else run into people ruining shutters by going too aggressive with solvents?
Guess I'm ordering the $80 version from the proper tool shop tomorrow, anyone else had those cheap tools let you down right when you're in the middle of a tricky shutter curtain job?
I used to go through a can of compressed air every week blowing out mirror boxes and sensor cavities. Finally got a Giottos rocket blower about two years ago and it paid for itself in three months. No more worrying about propellant residue or condensation ruining a clean. I also stopped getting those weird sticky spots on low pass filters that I could never explain. Has anyone else had that issue with canned air leaving a film on things?
I went to clean this used camera that had spots all over the images. The owner said it was just dust, but when I looked at the sensor under a loupe, there was this sticky residue from some old cleaning solution. I used a fresh swap with just a little methanol and worked from left to right in one pass. After 3 passes total the sensor was spotless and the test shots looked crystal clear. Has anyone else run into residue problems from people using the wrong cleaning fluid?
I was at the Philly camera swap last Saturday and this retired repair guy, Frank, watched me work on a beat up Nikon F2. He said I was using way too much lighter fluid on the shutter blades and that less is more with old lubricants. He showed me his technique with just a drop of naptha on a Q-tip and it worked better than my usual soaking method. Has anyone else been over-cleaning stuff like that without realizing it?
I spent two hours fighting a Leica M3's vertical alignment last week, but a Canon 7 I grabbed for parts lined up in 15 minutes with the same screwdriver. Anyone else find the old Canon and Nikon rangefinders easier to calibrate than the German stuff?
I bought a fancy ultrasonic cleaner from a shop in Portland last month thinking it'd save me time on old Zeiss glass. Cost me 90 bucks and it left a weird residue on three lenses I had to redo by hand. Anyone else had bad luck with those ultrasonic tubs for delicate optics?
For years I hit every sticky shutter with 91% isopropyl like it was gospel. Changed my mind after a 5D Mark II came back with intermittent ERR 20 codes 6 months later. Switched to dry cleaning with a microbrush and only use alcohol if the foam is actually gooey. That was probably 3 years ago and my repair success rate bumped up from around 80% to 95% easy. Anyone else find alcohol does more harm than good on those ribbon cables?
He watched me dunk a shutter blade in naphtha and said 'you're etching the lubrication seats, kid,' so I switched to ultrasonic cleaning with a specific 3% solution and my CLA failure rate dropped from about 1 in 4 to maybe 1 in 12 - has anyone else had a repair guru totally change their process with one comment?
Got a customer's vintage Pentax Spotmatic in last week with a sticky shutter. I had to pick between rebuilding just the shutter blades or swapping in a whole replacement lens unit from a donor body. I went with the rebuild because I wanted to save the original glass, but it took me 4 hours of fiddling with tiny screws and the timing is still off by half a stop. Anyone else wrestle with this choice and regret not just swapping the whole assembly?
Had a dusty old Nikon F2 come in last week. Customer said shutter was sticking. I always just use canned air. But a buddy from the local camera club handed me a rubber blower. Said it was a Giottos. I laughed. Tried it on a mirror box full of grit. Thing worked way better than my cheap puffer. No moisture issues. Now I'm a convert. Anybody else swear by a specific cleaning tool?
I had a client's Leica IIIf come in for a shutter curtain replacement. I could pick between a donor camera with a wrecked exterior but good curtains, or a clean body that cost 60 bucks more. I went with the junker because it was half the price and I figured I could just swap the whole curtain assembly. Turned out the junker's curtain was actually in better shape than the client's original, and the whole job took me less than an hour. Has anyone else found that ugly donor cameras can be hidden goldmines for parts?
Was going through my logbook from the last 3 years and counted 503 shutter replacements. Never thought I'd see that many. Anyone else keep track of their numbers like this?
My bench is covered in a pile of scratched lenses and half-fixed Minoltas from the last 30 days, and I'm pretty sure I forgot to eat lunch like 12 times, but hitting exactly 500 repairs just made me wonder if anyone else loses count halfway through a stack of bodies too?
Got a Pentax Spotmatic in last week with a stripped tripod mount hole. I went with the timesert since the helicoils I've used before seemed to back out over time. It held up fine during testing, but has anyone else noticed timeserts being harder to install straight?
