thanks Magdalena.

I recently purchased some aputure trigmaster ii radio triggers (x1 transmitter and x2 receivers) from a forum member, and already have a metz 50 af-1. Been having a bit play and they work great.
Seen as though ive got an extra receiver, can anyone recommend a cheap manual flash for the other?
Theres some neewer ones on amazon for £29, but ive no experience of them. I dont want to spend too much, its just for a secondary off camera light source.

Payment sent.

You have a pm.

that would be great. I'm not in any hurry, so will give you a pm after the 20th.

Anyone got one they dont use, and willing to sell for around £60?
Long shot, i know, but worth asking.

I would guess that it is something on the sensor, especially if its in the same area of an image, and using different lenses.
I'm sure someone more knowledgeable will be along soon, and possibly give you advice on how to clean it, if that's what it is.
I have never leaned a sensor, so would be reluctant to offer advice.

Holding "mode" while turning the flash on will tell you what firmware you have.

Hopefully i can help with this....the firmware update bit i mean.
Ive got a metz 50af-1, and having checked ealier (after reading this thread), it was on firmware 2.0.
Now, im not tech savvy at all....but ive got a son who is!!
So,
On the firmware update instructions, it says that the computer will recognise the device (i think its step 3.2).....mine didnt recognise it either.
Ignore that step, and go to step 4.0. Double click "FirmwareUpdateGB.exe", and follow the instructions from there.
Im now on firmware v5.0

Couldnt agree more.
I dont post often, but do check in every day (a few times a day tbh!!), and very rarely submit an image, but i love PU.
Well done and thanks John.
