50-150mm Lens Out Focus

[wkhang]

Hi,

I just got my 50-150mm last week, when I run a test on my Red camera, the 50-150mm is OUT FOCUS during pull out but for 18-50mm is no such problem. Do anybody facing the same problem? Please advise.

Thank you.

Best regards

I'm having the same problem. I sent mine back to Red. I also had another issue where my lens was showing a very weird blur on the left side at 150mm. But I was told it might be sensor aligning. I should here something today and I'll update you soon.

We've seen several RED lenses here for back-focus adjustment.
It's not uncommon. Lenses wear and must be adjusted regularly.
This is true to all brands of lenses.
You will notice it more on the 50-150mm due to its longer focal range.
Any owner/operator should establish a good relationship with a rental house or repair facility to make sure their lenses are calibrated properly at all times.

Mathew, I see you mention lens wear but mine was brand new and a few issues. I'm not worried at all RED won't take care of this but I hope I don't have these problems come up frequently.
