If the picture turns out dark


  1. Lower the shutter speed
  2. Raise the ISO Number
  3. Switch position to allow more light coming through the lens into the camera imaging sensor

FULL MANUAL LENS, no electric contacts→no auto focus→no image stabilization, require more exprerience with Manual Exposure. Also, the aperture value is not displayed in the camera.

  • 67mm filter size.

  • Because our products are manual focus lenses with no electronic contacts, Please set the camera to M mode.

  • First, please rotate the focus ring on the body at the front of the lens to focus. If it is still blurry, it is recommended to use a tripod and time-lapse function to keep the image stable.

  • The photo is too bright because it is overexposed, in this case you need to lower the ISO and increase the shutter speed. If the photo is too dark because it is underexposed, you need to increase the ISO and decrease the shutter speed.

Great long range lens for an inexpensive price. It is a bit stiff when adjusting your focal length and focus. So definitely not as great for dynamic situations where your subject may be changing distance from you fairly quickly. I'm pretty new to photography but I've had lots of fun trying to capture images. Attached some images taken with the lens in varying light and distances from 15' to over 300'.

For the price this is a great lens. It gives good images, reasonably sharp. It also works better with other lens add-ons (e.g. 2x telephoto attachments that screw onto the front of the lens) because it will focus past infinity. Build quality is solid. The ring locking the zoom (which then allows focusing) is primitive but adequate.The lens is basically a telescope with a camera mount attached. It does not have a diaphragm (so no choice of f stop) and there are no focus marks, you just turn the focusing tube until the image is focused.Color seems ok, I didn't notice any obvious chromatic problems. But I just took some landscape pictures, not sure what it would do with something like astrophotography.The lens will also work on any camera - it's an M42 mount with an adapter provided. So if you also have a different brand camera it will work using a different adapter.A nice long telephoto for "the rest of us". You won't get the image quality of a $2000 lens but also won't break your bank account.

I can go to an outlook in my town, see the one city that's 20 miles away, take a picture, and it's as if I was standing curbside to a house the picture is so good. Works great for planes and birds that are far away too. Great for the price!

The plastic that holds the tripod to it broke off after the first month

It can zoom to a farther distance but can’t get a well focused shot. You only rely on the shutter speed and ISO adjustments. It is frustrating if you want to use the aperture. The ring that is used to hold for tripod attachment split broken after few usage. It is not a good product. Save yourself some money and buy a good and reliable lens even if it costs more.

I love the zoom on this lens. It is crystal clear once it is focused in. I'd say I'm taking photos from around 100 yards and it is great. It does add a lot of weight to the camera but I didn't mind that. I would absolutely buy this lens again for long range photos.

It focuses beautifully, but when it arrived the cover was jammed in and was difficult to get off, there was a small crack mid way down, but small enough to deal with it. Today the crack broke off. Of course too late to return.

This is a great lense for cheap. I’m able to get high quality shots of wildlife with this attached to a different cameras. There’s no weird filter, vignette, or resolution. The only con is the weight, but that’s a known issue with camera equipment. I’m very pleased with my purchase!

The ring that grips the lens and mounts directly to the tripod snapped when tightening. It felt loose when I tightened it normally, so I tried going just a bit further to avoid any movement when shooting and the plastic broke.The lens itself is quite nice for the price. Not as sharp at 800mm as a native lens, but you really can’t beat the price. Solid all metal construction, the focusing ring is smooth with a good rubber grip (and necessarily stiff so you can find focus easily). Overall it’s a great lens, though I wish the aperture had more range. I have a 55mm-210mm Sony lens with f32 at 210mm. Helps for long exposures at night.

J'essaie de prendre des photos avec mon appareil canon r10 . J'ai installé une bague d'adaptation R/EF.... Je ne comprends pas pourquoi je n'arrive pas à prendre des photos en mode manuel. Merci

Vorher hatte ich ein Teleobjektiv 70-300 mm. Den Unterschied habe ich nun gesehen. Das neue Objektiv ist sehr stabil und auch ohne Automatik kann man irre Fotos machen. Ich freue mich auf meine nächste Fototour durchs Gelände. An meiner Kamera habe ich keine großen Einstellungen vorgenommen. Es hat einfach gepasst. Preis-Leistung ist top. Daumen hoch.
