ok, besides the obvious chromatic aberrations and lack of crispness, this lens is worth the money in my opinion! the focus ring is tight, but that’s alright because it allows better fine adjustments. the focal length doesn’t actually lock out, but it’s tight enough that it doesn’t move when focusing. if you’re wanting a thousand dollar lens, pay the money, but for the $50ish bucks i paid for this, i’m extremely happy (as long as it doesn’t fall apart).
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 nchste Fototour durchs Gelnde. An meiner Kamera habe ich keine groen Einstellungen vorgenommen. Es hat einfach gepasst. Preis-Leistung ist top. Daumen hoch.
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!
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 am an absolute beginner at photography so I bought this lens. I tested it out today and I think it’s OK especially for the price. I have a lot of learning to do but it took some decent photographs from a good distance.
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!
EARLIER REVIEW-
Lens works fine enough with ok image quality, but the provided T ring broke into two pieces and the tripod mount snapped almost immediately. Got about two days of use from it before it’s essentially useless as I can’t get the broken ring off to even replace it. Other reviews are good so mileage may vary but I’m processing a return or replacement and I’ve owned this for three days total :/
However, for the price, this isn’t too bad. Ideal fora beginner maybe
No stabilisation so a tripod would be a must and no electronics so all focussing is by hand.
Also, with an F stop of 8.3 the best light possible is needed.
The locking screw to rotate the lens is weak and needs careful adjustment
The lens diameter is small and might be better for video.
It isn’t a lens we would buy but for the amateur or beginner, its a start.
