Focus Ring Detached From Inner Focus Track

By Jacob
Rated 1 out of 5
Date: 2025-11-06

The Lenses Work Well In Most Scenarios, But The Focus Ring Has Detached From The Inner Focus Track On Our 50mm. The Focus Ring Now Slides Freely Around The Outer Housing, Without Moving The Lens Focus Elements. The Only Way To Focus The Lens Now Is To Slide The Ring All The Way To Infinity Or Minimum Focus To Catch The Inner Focus Track Again, But It Detaches Consistently. The Lens Is Now Only Usable Manually And Can No Longer Be Used With A Focus Motor. Even Manually The Focus Will Be Inconsistent And Unreliable.

Pretty good

Good lens but the focus ring is very stiff for focus pulling.

These lenses vs the Rokinin cine lenses? What would the difference be exactly?
Asked by: Benjamin
The Rokinon's have faster apertures The Meike lenses are smaller and have longer focus throws (which makes them more accurate to focus). It is also worth noting that Rokinon has several lines of cinema lenses from their DS series to their Xeen and Xeen CF. The Meike are closest to the Xeen CF in build quality. The Meike are compact sturdy lenses.

if the t stop is T2.1, is the f stop f1.8?

if the t stop is T2.1, is the f stop f1.8?
Asked by: Brenton
There isn't a constant F to T-stop conversion ratio since the T-stop is a measurement of the light being passed through the lens where as the F-stop is the size of the opening of the aperture. The F stop is only dependent on distance while the T stop is effected by all the things that change the amount of light passing through the lens to the sensor. But it is safe to assume that the F-stop is going to be a smaller number than the T-stop.
