I normally have mine attached to a cotton carrier vest, but the weight is all supported by the lens foot. I think it’s just a combination of taking it off that vest and in and out of the vehicle that has probably caused mine. I will most likely put a dab of blue Loctite on there later today Just to be safe. It’s really strange because if you were just looking at the screws, you would never know they were loose. They were still flush with the housing, but I turned all of them almost a full turn.
Yes, exactly the same in my case- there was a tiny bit of play & I had assumed that it was due to wear & tear from TC use, but the there were no indications that the screws were loose (they were flush as in your case- see below).
I wonder where that screw ended up at lol
Haha, indeed- I suspect it fell off when I removed the lens at some point!
Yeah, this is definitely the first time I’ve ever seen or heard of this I mean .060 of an inch is a tremendous amount of play in that mount. This could’ve been leading to some of my focus issues as well, but this is definitely going to be a regular routine check that I do on all my equipment once I get home today I’m gonna check the Screws on the front of all of them rather be safe than sorry
I am using 2.0 Phillips and have two different kinds as shown.
Wow (I say as I run to check the tightness of every adjustable screw on all my gear!
).
Yup, I'm in the habit of grabbing edge of lens hood and camera to lift my 600 tc out of the cotton carrier; gonna be both hands on the lens, to do so going forward.
I think mine is primarily from getting it out of the vehicle and off the vest as you mentioned. This morning was always two hand approach. This could have ended really bad for me.
Very badly. And for some loose screws!! Great the problem was identified and you got it fixed!
I’m really surprised that many more were loose on the other items. That’s just something I have never even thought about checking over the years.
Although your probably fine with a small Phillips precision screwdriver, it is advised not to use one due to possibly stripping the screw head if you overtighten . I would recommend the following;
I do have JIS and Phillips I saw no difference whatsoever in either bit with these particular screws. Hopefully there won’t be any more issuesAlthough your probably fine with a small Phillips precision screwdriver, it is advised not to use one due to possibly stripping the screw head if you overtighten . I would recommend the following;
Sony teleconverter flange screws are very small precision screws, and they are typically JIS 0 or JIS 00 size.
JIS 00: Best for very tiny electronics screws like those found in teleconverters, camera mounts, and lens assemblies.
JIS 0: Sometimes works if the JIS 00 is too small or if the screw head is slightly larger.
Important tip: Do not use a Phillips screwdriver, even if it seems to fit—JIS and Phillips have different internal geometry, and using Phillips can easily strip the screw.
Good luck
The difference is hard to see, but here is a breakdown:
Yeah, like I said, I’m aware of what they are and have a few of them, but for some reason in this case, it almost seemed like the precision Phillips fit more snuggly. They’re both nice to have though because there are certain things the JIS will only work on which I’ve ran into in the past.
