Hi guys,

I went to do a paid job this afternoon and used this lens. At first everything was working all fine and dandy, but all of the sudden during a (really) important moment, the darn lens stopped changing the aperture with the XT3 front wheel dial. It just stopped working and I could not change the aperture. It is sooooooooo frustrating when stuff like this happens and you look like an idiot in front of your customer because you can't change settings to get the right exposure. Talk about bad timing

I should have removed the lens to see what happens and maybe that might have fixed the problem back then, but I just didn't think of doing that right at that moment. How stupid of me. After I got home I plugged the lens back on and it is now working as it should. I am so upset right now. It is so annoying when your gear fails you right at the worse possible time hahaha!

I kept pressing the front wheel/dial in but the camera and lens would not respond. The lens firmware version is 1.00. I don't think there is a newer updated version. My question is did I do something wrong that I'm not aware of, perhaps I pressed something that I shouldn't have?? But again like I said the lens is working normal now so I'm really frustrated right now because I can't afford to use gear that simply doesn't do it's job when it should. Has anyone else encountered this problem? If I did something wrong I would like to find out to correct this situation otherwise bye bye to this lens.

Is pass midnight here so I will catch up tomorrow thank you so much for your input.

Sorry to hear about your experience. But it only shows how important it is to know your gear inside and out when shooting for a client.

Yeah seriously man.  It just sucks when your camera has or does “hidden” weird things when it shouldn’t.

While I don't have the Tamron, I've had a few lenses without aperture rings (XC ones and the original pancake), so I think I've come across similar situations.

Perhaps the aperture value showing on the screen/EVF was in white instead of the usual light blue? This denotes aperture is set to auto. On lenses not having an aperture ring, rotate the wheel associated with aperture to the left (counter-clock-wise) and you'll move past that auto setting to manually set values.

I have no idea what color it was when it locked up on me, but right now I’m changing and rotating the wheel and it stays in blue. I’m rotating it left as you said as well as the opposite direction and I can’t get it to turn white as you said. I don’t understand how you would switch to “manual”. Does it work differently with the XT3?

I hope this solves it for you. To be honest, I don't really know why Fuji cameras do that, it would sometimes randomly occur (mostly after changing lenses).
