* SOLVED * Focus problem w/XCD 120M

isarus · April 08, 2018, 02:40:39 AM

* SOLVED* Hello I'm getting frustrated and wonder if some one else have this problem: While using manual focusing and moving slightly the focus-ring and then, when near pristine focus the servo kicks in - and automatically move the lens totally out of focus. It is totally impossible to use manual focus with this lens. Anyone else?

Kent,

I have had problems with the 120 auto focus not working correctly. In my case, the auto focus indicated that it had focus, but the image was completely blurred. I have also experienced the 120 not finding focus. That said, your description is exactly the problem I experienced with my 45mm lens. When it happened I had to remove the battery and restart the camera to get it back in line. That particular issue has not happened since. Given that you have experienced this on the 120 and I on the 45 might indicate that it is a camera issue as opposed to a lens issue.

In my case, i was shooting with a Profoto Air Remote TTL-N attached to the top of the camera. I don't know that it was related to the issue as in one instance the Air Remote was on, and the other it was powered off. I will say that I had been shooting for over an hour when the issue started, and as I said I finely reached the point where I had to remove the battery. I should also note that during this same shoot I experienced a white screen on the EVF such that the camera was unusable. At that point I had to remove the battery.

I did reach out to Hasselblad US about the issues I experienced. They asked that I collect some additional data next time the event took place, and they did not know, off hand, what might have caused the problems. Not much help I am afraid.

Well, I guess I might have a slightly different problem. The focus-servo just goes banana on the 120 when I try to focus manually. None of my other lenses have that problem. In my case its easy to replicate - just use the focus ring and manually set focus in small steps - and suddenly the servo take command and sending the lens totally out of focus. I'll try to mount the lens and remove the battery and restart. Let you know.

Nope, did not work!

Might be a stupid question but have you updated to the latest lens firmware that came out about two weeks ago?

isarus · April 08, 2018, 06:32:43 AM

Yes Bill, I did!

I share the difficulties of using this lens for both street and landscape photography. My 70 year old eyes are not adding to the solution. My self taught method of using this fine lens has me pre-focusing the lens to an approximate distance after I have selected an IOS and an f/stop. Doing the pre-planning above, I am often able to capture the photograph without the lens going into autofocus fit. My normal walkabout kit is the 45mm and 90mm and a spare battery: Hard to criticize these lenses.

Right. The lenses are razor sharp. My other lenses works as expected. It is just the 120 that behaves strange. It is not usable for manual focusing and I'm afraid it is broken or buggy in some way.

Ouch. This is a lens I really would like to get but I am skeptical seeing what others are enduring. I have the 45 and 90 which are performing great.

Is the AF setting on: Full? I had it ones when this setting was on Near...

One would think that if you are in manual focus that the servo for focusing would be turned off completely. I am guessing that there is an issue inside the lens firmware and it needs to go back to the mother ship for evaluation.

Yes. I've tried all settings to no avail. Will open a ticket with HB. The XCD 30 and 45 both acts normally. Will let you know.

Yes I've opened a ticket with HB and will bring the lens to Stockholm tomorrow. They will send it to Gothenburg. So, bye, bye for a while.

Thank you Nick.

Just realised that HB just released FW 0.5.20 for the lenses. I currently have 0.5.16 and there is no ReadMe to the new firmware so I do not know whats fixed. I'll install the new FW now and let you all know......
