Does Otus 85 Canon Mount work on Ursa Mini Pro?

PostFri Oct 19, 2018 7:55 pm

Hi I’m at a event and tried to put my Otus 85 on my UMP. When I put it on I’m not able to change the Iris or aperture of the lens via the iris control.

Does this lens work on the UMP or is there a step in missing?

It should work, check the heads up display pull down on the f=stop at the top of the screen and make sure you do not have auto iris clicked on th elite level box in the lower right hand corner that pops up with the iris slider. Also check to see if the iris slider works to control the f/stop. The Iris control wheel also has several settings, be sure to select Iris on the switch in front of the wheel.
Cheers

Thanks Denny!


I tried using the lens on a DSLR and I got the “F - -“ error. So I think it’s an issue with the lens pins in the back of the lens. I’m going to try to use some cleaning solution on the pins. If not do you recommend some other home remedies, or should I prepare to get it repaired.

It’s a brand new lens only use once. I can’t thibk of how I could have damaged the pins after using it only once.

If cleaning the pins does not work, return it to the seller, and get it replaced/repaired at their expense.
Also you ave the Zeiss guarantee to use to get it repaired, if the seller is unwilling.

Yeah, I’ll have to get to start the process on Monday!

The only thing that I can think of causing the issue, besides a faulty lens, is the MC-11 Sigma Adapter I was using. I’m not sure how, but maybe using the adapter was the cause of the issue.

Great gads Batman :!: You didn’t say you we’re using an adapter! POW, Bam... :roll:

This is the most likely issue, it is the adapter, not the camera or lens, 90-percent of the time, especially third party adapters which are reverse engineering the interface.

Why are you using an adapter, isn’t the lens a Canon mount or ? The Pro has its own mounts for Canon EF and Nikon F, along with PL and B4 mounts.

I was hoping it wasn’t the adapter!


I use a mc11 adapter with a 55 Zeiss and it’s been working fine.


I got the canon Zeiss so I could use it on my Ursa as well as on a Sony Mirrorless for photos.


Does anybody recommend a canon lens to Sony emount adapter that they think would work better.

Or is the problem I’m having a unfortunate inevitable side effect of using adapters?

OK, you have totally lost me here. The MC-11 Mount Converter enables the use of Sigma EF-mount lenses on Sony E-mount mirrorless camera bodies. Why are you using this on the Ursa Mini Pro?, it will not work or even fit, as the UM Pro is not a E Mount. So what camera are you trying to use the MC11 adapter with?

Does the EF Optus work on the UM Pro with the Pro’s EF Mount? This was your original question, now you have added a Siny mirrorless csmera to the mix.

Sorry for the confusion, i'm using the MC-11 adapters when I put my otus Lens on a Sony e mount body.

I'm using the Canon mount ursa so im just attaching the otus lens to it.


I use the Zeiss Lens on my sony mounts for photos

and the Zeiss lens on my UMP for video.

I bought the Zeiss lens so I could use them for photo and video both!


I first tried to attach the Lens to the UMP and I couldn't get the Aperture to change, I thought it was the UMP causing the issue, which is why I made the initial post.


Later that night I then attached one (with the MC-11 adapter) to my sony e mount camera and got the "F--" error.



So I realized it wasdn't an issue with the UMP, it was an Issue with the Lens




So thats where I am now! I'm hoping to get it repaired or replaced.



After that I have to decide on weather I should give up using them with adapters, or try a new adapter.
