MZ-5n - time to call it a day?

Update on my MZ5N woes (or woes no more?)

I was reasonably happy that I could follow the instructions on Ipernity to change the wheel, other than the desoldering and soldering, as I am not confident with my soldering skills. I invested in a new soldering iron with a 0.2mm tip and adjustable heat, some fine lead solder and some solder wick, and spent a bit of time watching tutorials on Youtube. I then ran through my practices - first a dead MZ50, then a dead MZ-7. There were some differences in the connections to the boards due to differing controls, but I successfully stripped both back to the motor gear wheels, removed the wheels and reassembled the bodies. Having done that with some success, I went through the soldering process on a partially dismantled MZ-5N. I found the soldering on the MZ5-N a bit more challenging - the contacts are more tightly grouped and some are close to plastic parts.


It was then time for my first actual repair, the victim being my newest MZ-5N. Again, I found the soldering challenging, in particular four short pillars that join the flash board to the main board. I had a problem that I hadn't had with the three practice bodies - one of these pillars came away at both ends. After struggling for some time to try to resolder it to the flash board, I gave up and swapped the board over for the one from the practice MZ-5N.

The next problem was that when I got to the gear wheel, I realised that I had ordered the wrong wheels. This was my fault - I followed the links above, but didn't realise I had to enter the width and hole diameter into fields on the manufacturer's website. The fields had default values, so I got wheels to that specification. Fortunately, one of the practice bodies yielded an intact wheel, probably the MZ-7, which had a mangled shutter. I fitted this wheel and reassembled the camera. Disappointment awaited when I fitted batteries and switched it on - there was a reassuring whirr I assumed to be the mirror gears resetting themselves, but the shutter wouldn't fire. Fortunately, I found this was simply because there was no lens on the body (I didn't know that an MZ-5N shutter won't fire without a lens). With the lens and back on, everything seems to be working fine.


I have reordered the gear wheels and will tackle the other MZ-5N when they arrive. I may then see if I can rebuild a third working MZ-5N from the two dismantled bodies I have.

Kudos to whoever posted the repair instructions and link on Ipernity and also with thanks to Not a Number for leading me to it.

Thanks to all, especially Not a Number for the link to KKPMO. This is exactly what I was hoping for and I have ordered three gear wheels in PMO. At the time of my last MZ failure, there didn't appear to be a source for replacements. I have taken stock and I have two intact repairable MZ-5ns, one in pieces and five dead MZ series bodies to practice on. I also, currently, have a bit more spare time than usual (as long as my wife isn't delegating DIY chores).

The repair I did on the MZ-10 was, as I recall, to loosen the motor and the metal plate between it and the gears, move the grey gear wheel as far along its plastic pin as possible, then cut the pin, leaving as much of it behind as possible, and remove the grey wheel. I was then able to replace the broken gear wheel with tweezers through the gap. It's not ideal as, apart from using an old wheel that may not last, the grey wheel is now only supported from one end, but it did work and I have run a couple of films through the MZ-10 since. The reason I ordered the replacements in PMO is that, if I am forced down this route again (although the five dead bodies should give me plenty of practice), I reckon I have more chance of getting them on the motor spindles with tweezers than I would with brass wheels.

I will report on my efforts.

I dropped a couple of batteries in my latest MZ-5n today, turned it on, pressed the shutter release and heard the whirr of death. This is my third MZ to suffer the mirror motor fault. The fault appears to be more age than use or abuse related - the last two to go were on the first press of the shutter release after the cameras not being used for some time. Looking on Ebay, nearly all MZ-5s and MZ-5ns listed are now as "spares or repair". Assuming there is no new fix, is it time to give up on what has been one of my favourite camera bodies? It looks certain that if I buy another, or an MZ-3, it will already be on borrowed time.


I still have an MZ-7 and an MZ-10 that work, but they are not nearly as nice to use as the MZ-5n. Incidentally, I did manage to replace the mirror motor gear wheel on the MZ-10, which I bought dead, without completely dismantling it. It works fine, but I wouldn't trust it too far, especially as the "good" wheel came from a body in my large and growing MZ graveyard.

Cleaning the Sensor of Ricoh GX100/GX200

Has anyone done this? My GX100 has some serious dust on the sensor that I want to clean off. I tried disassembling it following instructions on here and elsewhere for GRs, but the interior architecture is very different. The back came off easily enough (no hidden screws and you don't need to dismantle the hotshoe), but I couldn't figure out how to remove the screen to get to the sensor.

Can anyone help?

Just trying to reply to this for the third time - my posts keep disappearing (moderated for some reason?). Anyway, I do actually have a Fuji bridge camera at home that belongs to my son and is, I believe a 9000 series. I had forgotten about it. That's probably the perfect camera for her and she'd appreciate the monster zoom range. He has upgraded and I'm sure would be happy for her to borrow it.

Thanks to all for your help

As I understand it, where she will be staying there's no power, but she will be making some visits to a town with power, where she may get am opportunity to charge a phone. If she took the K10D, I'd buy a fresh set of rechargeables and have her take two sets of quality disposables with her, rather then trusting local sources.

If it were me, I'd probably take the MX, Espio Mini and either Espio 120S or Olympus Mju zoom. I wouldn't lug around both film and digital kit and get more pleasure from shooting film.

Thanks Saltwater,

I do have a 40mm pancake lens, but it's manual focus and my daughter isn't a photographer. Having said that, I could set the K100D on AV, ISO to 800, lens to F16 and infinity and she could use it like a hyperfocus P&S. Then again, 60mm equivalent focal length is a bit 'neither fish nor foul', which is why I almost never use the lens on a digital body.

If I had the DA pancake, I wouldn't risk it on this trip.

Solar charger is a thought - I just had a look on Amazon and they start at around 18, however it would require a camera that charges through a USB port and any I have have a dedicated external charger that connects to mains power.

My daughter will be travelling in Africa this summer and won't have access to electricity. She's not a photographer, but does want to take a camera on this trip, so I'm thinking she needs something that takes standard disposable batteries- AA, AAA, CR123 or such like. I could lend her my K100D, but she's planning on travelling light. I have loads of film compacts she could choose from, but then she's need to pack film.

So, any recommendation for a simple digital compact that takes disposable batteries and won't be a disaster if it gets lost, stolen or broken?


Thanks,

Thanks for help and advice on my detached lens mount. In the end, I went for the original screws supported by correction fluid on the threads and a bit of non-permanent glue around the screw holes. The worst part was trying to reattach the spring to the earthing cable. In the end, I gave up trying to solder it and used a spring from a dead body with cable attached, so I soldered cable to cable.

Here are a couple of shots I took early yesterday on a cold and murky Hastings beach. The previous evening was fine and clear and I was hoping to catch the sun rising, but it didn't show its face into well into the afternoon.

Not sure this is the right place to post this, but I'm after a bit of advice. It's not strictly a K20D issue - it could apply to any plastic bodied camera with a steel lens mount, but in my case a K20D is the subject.

I took a punt on a damaged K20D last year. It had clearly been dropped with a heavy lens attached as the mount was off the body and badly distorted. 47 for the body, about 20 for a new mount and a tenner or so for a battery had me up and running.

Because the mount had been torn off, the screw threads were all partially stripped in the plastic body. They were just about tight enough to hold (as a precaution, I have avoided heavy lenses), however the camera has suffered from some more rough handling (not by me) and the mount is off again. I haven't tried refitting it and suspect that now is the time to address the issue properly. As I see it, options are:

  • Source some slightly larger screws to cut new threads in the body (hopefully, without needing to adapt the mount itself)

  • Supplement the screws with glue, or use something like Loctite

  • Replace the body (I'd be stretching affordability there)


Ditching the 'o' ring and sacrificing weather resistance may be necessary, as compressing the ring adds to stress on the threads.

Any ideas anyone?

Thanks,

As mentioned in my last post on this thread, the new laptop was subsequently upgraded to Windows 10. Today I tried using the scanner for the first time and my original instruction let me down. The solution was in Sark's post - add the line about the twain source in system variables. In windows 10 when you select "edit" in environment variables you are preseneted with a list and the option to "add" Paste the line:

C:\Windows\twain_32\CNQ8400

into the new box that opens for you. It's slightly different to as described in Sark's post for Windows 8. you do not ned the quotation marks.

Assuming all are in working order, I'd keep the MX and the MZ5-N. Anything the ME and ME Super can do the MZ-5N can do too; the MX gives a different shooting experience. These are two of my favourite SLRs.

Since starting this thread I've upgraded my laptop and, thankfully, the new one has good old Windows 7. This means that one of these days I'll have to upgrade to Windows 10 again. When I do, I'll be referring back to my own thread for instructions.

Hi,

I thought I'd struggle with installing my Canoscan 8400F under Windows 10, remembering what a faff it was getting it to work under Windows 8.1. As it turned out, it was quite easy - here's how I did it:

Download Canoscan Toolbox 4.9 software. I already had the install file saved - I don't think it's hard to find on the web. There are later versions - don't be tempted.
Locate the file on your computer, right click it to open properties, select compatibility and set this for Windows XP SP2.
Right click it again and run it as administrator.

Re-start the computer as requested.

Download TWAIN driver file 8400fvst6410231a from Canon's website (note I think the 64 in the file name might mean 64 bit, so you may need another for a 32 bit system).
Locate the file, right click it to open properties, select compatibility and set this for Windows XP SP2.
Right click it again and run it as administrator.
This will create a folder called 8400fvst6410231a_64en (again, might be different for 32 bit) in the same directory as you downloaded the file into. In that folder is a file called SetupSG. Run that to install the driver.

A restart here is not required

This worked right away for me. I had the scanner connected to the computer all through the process and don't know whether this makes a difference. You will see Canoscan appear in Device Manager if you have it open when you install the driver.

Hope this saves a few people some time and grief. The process is probably the same for other older Canon scanners.

Which 35mm zoom compact?
Posted By mzsaunders

So, having started looking, I ended up with a small collection of film compacts, of which only the above mentioned Espio 120 (at 7.28) cost more than 3; most were 1, one was free. From memory, they are Espio 120 and 125M. Yashica Zoomtec 90 and Microtec 90 (I actually got two of each of the Yashicas, one of each was a dud), Olympus Mju zoom and Mju III (both of which turned up at the same local charity shop in consecutive weeks) and Samsung Riva 170. For good measure, I also got myself a PC35AFM for 1, but haven't tried it yet.

As predicted, none has had more than one film through it and I didn't bother with the 125M at all. I reckon the best results were with the Espio 120 and Mju Zoom, which I took to a 50th and an 18th birthday party respectively and got some good people shots. I guess this sort of use was pretty much what they were designed for. The only one I tried taking to a gig was the Microzoom 90 and the results weren't too good with Delta 3200.

So, it was a fun exercise, but the lesson was stick with the SLR when lighting is tricky and forget about taking photos at a gig that doesn't allow SLRs. I took a few of T V Smith playing The Railway in Southend last Friday with the Z1-P, 50mm F1.7 and Delta 3200 and was quite pleased with the results. I'll post some later.

thanks Christian.
The four compacts have all arrived now. The Yashicas are solid and chunky, though far from pocketable. One has a fault, but I reckon the other will perform pretty well, as all my Yashicas have nice optics. I have no real use for it, but will run a film through it to see.
The 125M looks like it was made down to a price. I haven't tried it yet as I don't have a spare CR123 battery around. 120SW is a nice size and looks well made. I had forgotten about the unlikely way the lens extends on these - enough to make a sailor blush. Again, I'll run a (fast) film through it and see what I get.

Thanks Christian. The problem with a wide fixed focal length compact for my purpose is that it will expose for the whole scene which, typically at a gig, will massively overexpose the performers' faces. I reckon the lack of any form of exposure control will be a bigger problem with a film zoom compact for this task than the slow lens. My usual camera for a gig is an SLR with 50mm F1.7 and HP5 or Delta 3200 and I meter manually, or dial in a couple of stops of underexposure. The gig I was at last week didn't permit use of 'professional cameras' (strange really when half the crowd are filming it on their phones) and I've never got good results with a digital compact at a gig, which is how I hit on the zoom compact idea.

I reckon my ideal for this would be a pocketable compact with something like 80 or 100mm fixed focus F3.5 or F4 lens, DX code override and manual exposure control or at least EV compensation, which I'm sure is too precise a spec ever to have been put into production.

I ended up picking up four zoom compacts over the weekend - the 120SW (7.28), Yashica Zoomtec 90 (1.50) Zoomtec 90 Super (0.99) and an Espio 125M (0.99). I'll be surprised if I run more than one roll of film through more than one of these, but as the lot cost me little more than the price of a film, who cares?

update - I bought the Espio 120 for the princely sum of 7.28. I didn't think I could go far wrong at that price.
I looked up some specs and, apart from a very slow lens (balanced somewhat by ability to use 3200 ISO film) it seems to fit most of my requirements.
I'm still open to suggestions.

Can someone recommend a 35mm compact with a zoom range around 35mm to 135mm and reasonably fast lens? Doesn't have to be a Pentax, but has to be available cheaply on eBay. A little control over exposure and film speed would be welcome, but may be asking too much. It can sort its own focusing out.
I have some nice film compacts (none of which are Pentaxes) , but was looking for one to take to a gig this week and realised I have this gap in my armoury (all are fixed focal length around 35mm)
There's an Espio 120 going cheap that might fit, but I don't know whether this is a good model.
