One of my PocketWizards has been a little flakey recently, it will work fine on a camera as a receiver and on the Studio heads, but will only randomly trigger if mounted as the transmitter on the hot-shoe. A quick dismantling session (there are only two screws on the body) and a peak inside didn’t show any obvious problems. However after reassembly it was clear that there was some movement in the hot-shoe mount, which as it moved was enough to break the contact with the PCB.
Anyway a small blob of glue is sufficient to stop it moving & now seems 100% reliable, I will order a replacement foot (if they are available) and replace the original, not sure that it will make much difference as I don’t know if the issue is with the foot or the body of the transmitter that is worn. We’ll see.
Having received a replacement rubber weather seal in the post this morning, I thought seeing as I had no football today get straight on with replacing the very worn one on my Canon 2x Extender. I have no idea how it became so worn as it is seldom used, probably less than a dozen times in the last 5 years.
Anyway a simple enough job, undo screws on the lens mount, lift the mount & slide the seal over, re-seat the mount and do up the screws, all in about 5 minutes, then a couple of test pictures to ensure that everything is in alignment and job done.
The Part Number for the seal is YA2-3463-00 and I believe the item is the same for most if not all Canon EF lenses that are weather sealed. I have a couple of other lenses that could do with the seal being replaced so I will confirm in due course.
Brilliant service from CPS, an EOS 1Dx that needed a new Mirror Box, Focusing Screen and Lens Bayonet mount. Dropped in to Elstree on Tuesday and returned via UPS on Friday. Only downside is that it looks like I have to recalibrate the AF Micro-adjustments.
After repairing the 400mm lens recently I have finally dropped my 1Dx that was on it to CPS Elstree, to have the mount replaced & a realignment carried out, hopefully won’t be too expensive. I have also arranged to have a second body that has “issues” looked at. I was informed that (as a platinum member) it should be a two day turnaround plus shipping time. Due to only having one camera that I am able to rely on, I have cancelled my trip to Jersey as the second body that I have is a very high mileage body with 600,000 activations which whilst good for it’s age is in dire need of a new shutter & mirror box as well as a complete service.
So… having found the locking tab for the lens hood, which in it’s bid for freedom only made it as far as the boot of my car, and not the gravel car park that I was in when it went AWOL, I thought I had better fix it. Before that I should just say that the reason I didn’t look in the boot initially is just that I am never that lucky, if something goes missing, it is never where you’d expect it. Today was a case in point, I dropped a 2mm E-clip, seeing as it was dropped on carpet, weighs F*** All, you’d expect it to be fairly close by, but no, searching with a magnet (always handy for these sorts of things) it had managed to travel 6 feet from where it fell.
Anyhoo, I wasn’t sure what size E-Clip was going to be required so I ordered a selection box from Amazon, with sizes from 1.5mm through to 10mm, as it turns out I was the 2mm one that I needed. I have never really given it much thought about how small a 2mm E-clip was actually going to be, well you don’t, do you?
So have assembled the bits required and tried a test run with a spare locking assembly, all went to plan, albeit bloody fiddly. So on to the actual assembly, as the Wedge & the Lock have be joined through the lens hood, it was a bloody nightmare. Holding together the Wedge, the Lock & the actual Hood whilst attempting to fit the E-Clip through a hole, onto a post, with a pair of tweezers. (This because of the last failure of the assembly, stripping of the screw threads required the application of some adhesive to screw threads)
So with the help of a magnet, and plastic bag (to catch the E-Clip if it tried to escape) a pair of iFixit tweezers a pair needle nose pliers and a small flat bladed screw driver, it is now Fixxored! The next job is to see if I can get someone to either machine or cast another wedge (maybe a few as I am sure there are others out there that could use a replacement) so that I have a full replacement for the part should the need arise. If you are needing a replacement, the official Canon part number is CY1-4292 which I also believe to be the same part for the EF300mm F2.8L IS, the EF400mm F2.8L IS, 500mm F4.0l IS & the EF600mm F4L IS, then get in touch as I maybe able to help.
Last weekend the Lens Hood lock on the 400mm decided to part company with the hood itself. Not a major problem, usually, except that it threw the circlip that holds the wedge (the black bit) in place & the wedge went walkabouts, So I get online to find a replacement, except that Canon don’t supply them anymore, despite the fact it is a common part across a number of lenses. So the search begins, after finding a number of ludicrous prices for the part, the most was some £600, although that did also include one of the screws, individually priced at £450.00!!!!!!!!!. A replacement complete lens hood is £700! Anyway frustrated by the prices I went and hunted in the boot of the car, on the off-chance that when it went ping it fell in there, rather than in the gravel carpark I believed it to gone.
So having found the wedge all I need now is a 2mm Circlip, so I have ordered a box of various sized clips (also known as E-Clips) which should be here tomorrow. I will also order a third party replacement hood from the USA, that will also work with the later version that I will be upgrading to later in the year.
After an accident with my Canon 400mm F2.8 L IS USM a couple of weeks ago, the lens mount needed replacing. Seeing as Canon won’t touch it, nor most of the repairers I have contacted, I decided that if I could find a lens mount I would do it myself. Now Canon haven’t supplied service parts for this lens for a while, and if they did they wouldn’t supply them to an unauthorised repairer like me.
Fortunately for me Google turned up a saviour in https://www.eurohitech.com. I ordered the part with not a little nervousness, a) because it was £180 and b) I had never dealt with them before. Anyway two weeks later I am holding the replacement part in my grubby little hands, Thanks Sushil.
So time to crack on, it is a really simple job, just a little fiddly. PH000 & PH00 & PH0 screw drivers, and a plastic tray with a magnetic screw holder and a small plastic pry-bar (spudger) is all that you need. Firstly it may be a good idea it mark the correct orientation of the mount, I used a black marker pen and marked the position of the lens lock receiver, on the body of the lens, next thing is to remove the baffle, which on this lens is held with 3 small screws (a lot of the budget lenses they just lever out), then three more screws to disconnect the electrical contacts. Undo the 4 main screws and away the mount comes, complete with rubber weatherseal.
The reinstallation is simply the reverse procedure.
***UPDATE: All tested and working perfectly, so will be used for shooting football tomorrow & Sunday, Yay!***
Needed a replacement battery cover for a Pocketwizard Plus X, so ordered a replacement from the UK importers Colour Confidence arrived within 48 hours, unfortunately I ordered the wrong part, it was only £9.95 so thought I’d keep it as a spare & order a replacement, however Colour Confidence sent me the correct part gratis. Brilliant customer service.
The replacement couldn’t be simpler, undo two screws & crack the case open, swap the back & reassemble.
