| Pros: | Small, lightweight, usefull | | Cons: | Not for modern lenses without aperture ring. | |
Bought it out of curiosity for 25€ (27$ ar current exchange rate) a few months ago.
Quite nice coupled with a SMC-M 135mm for wacthing birds in the backyard.
Tried to use it with Sigma 50-500 HSM, but it is very dark. Probably due to the aperture being always closed to its maximum setting, and no aperture ring. Hence the main negative point listed. Otherwise, would give it a 10.
Otherwise, a very nice addition to any camera bag for outdoor expeditions if you have a compatible lens with you.

| Pros: | superb magnification | | Cons: | not for zoom lens? | |
Bought it out of curiosity . 99 euro. Bit expensive for a curiosity item, but looked cheap enough compared to new ones like lens2scope kenko (160..200 euro, seems popular at birdforums)
Works fine on my primes like pentax-k 200 f4 en -m* 300mm f4. Bright and sharp.
On the (cheaper) 200mm sometimes there can be noted some purple fringing-like aberations, but not annoying.
With these lenses it outperforms my standard binoculars..., so I am happy user: it is a less bulky add-on to my camera backpack than a binocular!
Looks a bit like a pirates or sailors telescope when you use it. Especially with long lens it draws attention.
On a longer and heavier 400 mm lens it gets more difficult to target handheld, maybe I should use a monopod for stabilisation.
If you find an older point and zoom lens (= single ring focus&zoom lens) targetting and focussing single handed becomes a lot easier compared to zoom lenses with seperate focus and zoom rings.
My mirror lens works also well but as a 500 mm f6.3 with shallow dof, focussing and targetting is on the edge: the viewing angle is so narrow that you easily miss your subject. The f6.3 of the mirror is not an issue, brightness is good to the human eye.
Added: I found out that older, one touch lenses (focus and zoom by one ring) are extremely convenient. While zooming looses sometimes focus to some extent, the fact that you can correct with one hand/zoomring makes it easy to find your subject using the wide end and then zooming in.... I am using now Soligor 70-300mm f3.8-5.6 MC C/D.
I tried it also on a newer era zoom lens , but found it difficult to focus/zoom/target.
Note that while zooming you lose focus on the zoom lens making the zoom less usefull for target finding: you have to focus and zoom - turning 2 different rings on your lens at the same time. (focus breathing? - i used a Pentax 55-300 4-5,8 HD Pentax-DA ED WR).
So the trick to use wide for finding your target and then zoom in, didn't work that well.
The magnification to the eye appears to be higher than the same lens on my aps-c camera .
Oh, and to remove it from your lens, push the little, round button on the side to unlock it.

| Pros: | converts your good lens into a scope | | Cons: | no | |
Today I've acquired a mint monocular converter K, mounted it on a FA* lens and was very impressed about the clarity and detail of a long throw (1000mm total). My wish for buying once an ED scope is now history. Even at short focus with a macro lens it is useful.

| Pros: | Optics and build quality are great, picture is upright | | Cons: | Does not open the aperture wide in lenses without aperture ring | |
This device does come in handy when outdoors with a camera and several lenses, as it turns a lens into a monocular scope / telescope.
So someone else can look through this while you are taking photos :-)
It has a built-in prism so the picture is upright :-)
Optics and build quality are great.
Focal length of lens should be at least 50mm and if it is very long you would like a shake reduction.
Great max. apertures are fun because then you get a very bright picture in dim light.
Unfortunately, if your lens has no manual aperture control the this adapter does not move the aperture of the lens wide open as it has no means to push against the lenses aperture lever.
You can then use a small piece of e.g. plastic to hold the lever in the wide open position, but that is always a bit of a hassle.
A very nice accessory.
