Review: Quality Lens - Great lens for the price. Only downside is that it is fully manual and not able to do autofocus. This makes it hard to capture birds in flight and get detailed photos. But for still instances, it works well with expertise and practice. Here are some of the pictures I have taken with it. I have had this lens for a year now, now upgrading to a Sigma 150-600 mm lens for the Autofocus capabilities. I really appreciated this lens for the convenient price.
Review: It's alright (Read) - This is amazing for the price, but it lacks autofocus and has a somewhat pixelated image. You get what you pay for, and it's also pretty shaky, but still great.

## Questions & Answers

**Q: Why can't I press the shutter after mounting the lens (An error page display)?**
A: Please do Enable the "Release w/o lens", and then you can press the shutter to take a picture.

**Q: Why does my picture out of focus and very blurry?**
A: Since our lenses are manual lenses, there are no electronic contacts for autofocus. Need to turn the focus ring (on the front of the lens) for manual focusing. If it is still blurry, use a tripod and time-lapse function to keep the image stable.

**Q: Why is F-- displayed and how can the aperture value be set?**
A: As the manual lens has no electronic contacts to recognize the aperture value, “F--” is displayed. The aperture value can only be adjusted automatically by changing the focal length. (420mm/F8.3 →500mm/F10→600mm/F12→700mm/F14→800mm/F16)

**Q: What if the image turn out bright?**
A: If the image is too bright, lower the ISO (e.g. from 200 to 100) to reduce the light sensitivity and increase the shutter speed (e.g. from 1/125s to 1/250s) to reduce the exposure and avoid overexposure.

**Q: What if the image turn out dark?**
A: If the image is too dark, increase the ISO (e.g. from 800 to 1600) to increase the sensitivity and decrease the shutter speed (e.g. from 1/250s to 1/125s) to allow more light onto the sensor.

### ⭐⭐⭐⭐⭐ Great price and quality
*by R***G on December 5, 2025*

I'm a novice when it comes to photography, and I've never used a ridiculously expensive lens, so I can't speak to comparisons, but I love the shots I get with this one. A tripod is definitely a must use, and I don't have a remote, so I use the camera timer to let it settle down after pushing the button. I have a Canon R100, and it fit right up. With some time and effort in making those adjustments, I can say I'm fully satisfied with the results. Pictures are 2 at 800mm and one at 600mm
