Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary

Quite a bit of distraction with all the vines but I thought it was nice to see them together.

Thanks, Harry

Here's a Tufted Titmouse, seems like we have an abundance of them around our house. Fast little dudes! Hopefully, I can venture out away from the house with this new lens, the weather has been wet and cloudy for days.

Thanks, Harry

Edit: I suggest you Not install this new Firmware - various users including myself experience the AF point jumping erratically, plus other issues.

SIGMA 150-600mm F5-6.3 DG OS HSM | Contemporary for CANON EF Mount Update

It has improved the stability of the image in the viewfinder, making it easier to confirm composition, thanks to the updated control algorithm of the Optical Stabilizer.

Cool, it was already really good once I used the USB dock to set the OS mode to dynamic.

Not updated my lens yet - I currently have my C1 set to Moderate View Mode for the OS which I think is fantastic. Be interesting to see how the update can improve on this..

Thanks for the headsup!
Harry

Updated the firmware this morning.

At first I thought the C1 switch was broken, I've assigned that switch to Moderate View Mode. On initial testing it would appear the OS did not make any difference at all, as if it's not working. Confused I set C2 to the same setting, again no difference.

After a reset I set C1 and C2 switches to "Moderate View Mode" still no OS.

Ok, this time I set C1 to "Dynamic View Mode" and C2 to "Standard" OS works again..

It would appear "Moderate View Mode" no longer works after this firmware

Anyone confirm before I email Sigma and tell them this Firmware is Broken?

I've always used dynamic a throwback to my years with the sport model .. I will have to borrow a usb hub to do mine

Contacted Sigma Imaging UK -

Initial reply:

"When the OS is customised to moderate view mode it is very difficult to see the OS working through the viewfinder. The OS is more effective but less visible. In dynamic mode it is less effective but more visible and in standard mode it is somewhere in the middle."

Which I think is incorrect according to the OS Mode description:

Moderate View Mode

"This mode offers excellent compensation of camera shake and achieves very smooth transition of the image in the viewfinder. The composition of the image remains natural even when the angle of viewing keeps changing."

My concern has been forwarded to the Japan office.

EDIT*

Received an answer back from Sigma Japan..

"OS operation in Moderate mode may not look as strong as former version, but the actual effectiveness is still very good, and it will be reflected in the better image quality ultimately.
So I guess his lens is not defect. Please inform the customer to set Standard or Dynamic mode in this case."

Great shot - Always nice when they land on your door step!

Did you upgrade your firmware?

Sigma states:

Update Date 2019.03.14

● It has improved the stability of the image in the viewfinder, making it easier to confirm composition, thanks to the updated control algorithm of the Optical Stabilizer.

They forgot to mention that it warrants another feature useless, I'm so annoyed I upgraded!

I updated the firmware,definite improvement to the OS I would say,I never quite knew if it was working at all before,works in all modes because I can hear it working,granted the moderate mode doesn't seem to do much but I don't use that.
