What are the best smartphone lenses out there and are there any decent optics tests online? I know brands like Moment lead the way (perhaps with their marketing) but are there better options for an iPhone 11? Looking for quality over price although of course when it comes down to it price will be a concern. Thanks.

- PRICE: $599
- STRETCH: 2X
- FOCUS: Double-focus
- PAYMENT METHOD: Paypal (fees to be paid after initial payment)
- LOCATION: Switzerland
- SHIPPING: Not included
- INCLUDED: Redstan rear adapter with foot support and Redstan front clamp (value = $100).
- CONDITION: No scratches and no fungus. Clean glass with the exception of a couple tiny spots on the rear glass. A couple of VERY light scratches that are only noticeable under a light source. Body shows some signs of wear but it works perfectly. Coatings are not flamboyant but the lens creates these signature purple/orange flares perfectly well. I wasn't able to get 1000% tack sharp images, so the lens might need to be serviced. It gives reasonably sharp results though, and my issue might actually come from my taking lens. Bought it from a fellow member of the Anamorphic Shooters group on FB and barely used it because of a decrease in filmmaking activity.
- COMMENTS: I can send some footage via wetransfer. Open to offers.

Hi,
5 months ago our company bought Zhiyun crane plus gimbal.
While we edited our footage we discovered that there is a problem in gimbal stabilisation. Though the gimbal was 100%balanced in all positions, it still appeared stabilization problem to every single shot.

This a video sample with the Crane plus and a Sony A7III.
I tried to sent email to the company but none of the emails in their site works and in the tech support on Facebook the answer was that everything is ok.
