Hot take: I finally switched from canned air to a proper air compressor for cleaning mirror boxes

For years I used those little cans of compressed air on every DSLR that came in, thinking it was fine. Last month I picked up a small 3-gallon compressor from Harbor Freight for about $120. The difference is night and day. The steady, dry blast from the compressor gets dust out of corners the canned air just pushes around. Has anyone else made this switch and noticed fewer dust spots after sensor cleaning?

I dropped $350 on a Horwell lens spanner and it was totally worth it

I mean, I was working on a stuck front element on a vintage Nikkor 50mm f/1.4, and my old cheap spanner just kept slipping and scratching the barrel. The Horwell one has these super fine, replaceable tips that actually gripped the notches without any play. It felt like a huge cost at the time, but it saved the lens and my sanity. Anyone have a good alternative for a mid-range spanner that doesn't break the bank?

My $40 investment in a set of JIS screwdrivers for old Nikons

I was working on a Nikon FM2 last month and kept stripping the tiny screws on the top plate, even with my best Phillips set. A guy at the local shop in Austin mentioned they were actually JIS heads, not Phillips. I bought a Vessel Megadora set for about $40 and the difference is huge, no more chewed-up screws. Has anyone else run into this with other Japanese camera brands from that era?

Question about a stuck shutter curtain on a Nikon F3

I was fixing an F3 for a client in Austin last week and the second curtain just froze halfway. I thought the whole gear train was shot, but after checking the service manual, I found a tiny bit of old lube had gummed up the pivot post. I cleaned it with a drop of naphtha on a cotton swab and it ran smooth. Anyone else run into this on the F3 or similar bodies?

I always used the standard 1.5mm driver for Canon lens screws. A guy in the shop told me to switch to a JIS #00 for the tiny ones. Tried it on an old FD 50mm and it was a game changer. No more stripped heads. What's your go-to for those micro screws?

Heads up about a weird film advance issue on old Minoltas

I fixed a Minolta XG-M last week that had a stiff film advance. The owner said it got worse over about three months. I opened it up and the old grease in the gear train had turned into a thick, sticky paste. It was like glue. I cleaned it all out with lighter fluid and put in fresh grease. The lever action went from feeling like pushing through mud to smooth as new. Has anyone else seen this specific gunk-up happen so fast on these models?

Vent: I was cleaning shutter blades wrong for years until a client called me out

Honestly, I used to just blast them with canned air, thinking speed was key. A guy brought in his Leica M6 last month and asked if I used a soft brush and lighter fluid, which totally changed my results. Anyone have a better method for old, gummy blades?

A customer told me my bench was too clean and it actually made sense

Can we talk about the shift from using alcohol to using naphtha for cleaning shutters?

For years, my whole bench used 99% isopropyl on everything... but after a sticky Minolta SR-T 101 last month, I switched to Ronsonol on a hunch. The old lube just dissolved cleaner, no residue. Is this a real change in the trade, or did I just get lucky with that one camera?

Vent: Mirror box alignment on vintage SLRs is way too fiddly...

You have to strip down the whole top plate just to tweak two tiny screws... and good luck if they're seized. It adds hours to a simple focus fix and tests my patience every time. Camera makers clearly didn't think about repairs when they buried those adjustments. Makes me wonder why I even take on these jobs anymore.

Pro tip: Manual focus checks often work better than digital tools

Many camera repairers say you must use digital calibrators for lens focus issues. I disagree from my own work. I have fixed lots of lenses by just using a printed test chart and looking through the viewfinder. This way, I can feel the adjustments and see the results right away. It works for old film cameras and newer digital ones too. Sure, those fancy tools are good for very tricky autofocus problems. But for most repairs, like sticky focus rings or slight misalignments, my method is faster and cheaper. I have had happy customers for years without needing expensive gear.

My old rangefinder's focus patch is fading fast.

What's the best way to restore it without special tools?

My eyes got really sore from microscope checks last week

I was checking a camera's tiny parts under the microscope for hours. Now my vision feels off when I look away. How do you handle eye fatigue during detailed repairs?

Called busted digicams hopeless, then the e-waste pile changed my tune

I used to tell clients to toss their old digital cameras when they acted up, thinking repair wasn't worth it. Then I visited a recycling center and saw mountains of electronics, including tons of cameras. I grabbed a few to tinker with and found most just had dirty lens assemblies or bad solder joints. Now I take time to fix even the cheap point-and-shoots that come my way. It keeps plastic and heavy metals out of the ground, which feels way better. I've saved hundreds of cameras from the dump by now, and my shop gets known for it. Customers are stoked to keep their memories alive without buying new. Honestly, seeing that waste pile firsthand is what flipped my view for good.

Paying top dollar for factory parts isn't always smart repair

I see a lot of talk about how only original parts from the camera company are good enough. I have to push back on that idea. Last month, I fixed a Sony mirrorless with a sticky aperture blade. The Sony part was quoted at a high price and would take three weeks to arrive. I used a quality aftermarket blade set from a supplier I trust, and the camera works like new. The customer was thrilled to have it back in two days. If we always wait for the branded part, we hold up people's cameras and charge them more. We should test and use reliable alternatives more often. It makes our service better and faster.

Showerthought: My trick for cleaning viewfinder mirrors without scratches

I mean, I used to worry about scratching them, but a microfiber cloth dampened with lens cleaner works best. Idk, maybe it's just me, but wiping in one direction from the center out keeps it safe.

Warning: My little cousin actually listened when I explained mirror alignment

He kept messing with my tools, so I sat him down and showed him how to check the mirror in an SLR. Now he points out when one looks off, and it's cool to see him pick it up.

From my bench: Everyone says to avoid touching mirror box foam, but I replace it by hand all the time.
