You get what you pay for and then some. If you are not a professional and are a budget photographer then this lens will be perfect for you.
Once the settings on your camera are set you can take some nice shots which I have uploaded three shots I took just this morning with my Sony A200 to show its magnification power. First with the stock lens @ 28mm then the Kenko lens with its minimum to it maximum without the 2x teleconverter. You can easily see the pictures come out pretty nice for a lens of this price.
Shooting at night is just not an option with this lens less you can take a long exposure or shooting a bright object like the moon. Obviously flash doesn't really help when shooting distances.
The lens is not fast but the brighter the day the faster it becomes but that's with any lens. I haven't tried to catch anything very fast like an animal running or a sports player but people walking, even jogging can be captured easily.
The lens is light weight but has enough weight to it where it doesn't feel like you're going to break it easily. I have been carrying it in my Canon camera bag with all my other gear and its held up nicely. Though, It's looking like I need a larger bag with all the gear I carry.
That's about all I can say about this lens. I have to give it 5 stars because for its price and what if gives you it's certainly worth all five of them. Now if we were to compare it to other more top of the line lens then less stars obviously but on its own, this is a great lens.
A few helping tips:
1: Anything with more magnification make any hand shaking more noticeable. Shoot with a sturdy tripod.
2: Even with a tripod you can transfer shake to the camera so also use a remote shutter controller to snap your pictures. If you don't have one or can't use one on your model camera set a time delay of a few second. That way you have time to pull away and let your camera and tripod settle before the photo is taken.
3: Software is key in making the pictures better looking. Even with good setting on your camera this lens can make things look slightly washed so with software like Photoshop you can adjust levels, contrast, brightness and more to make a cleaner looking photo. Filters help and if anything a UV filter is nice if just for the protection of the main lens but software can help as well.

I own this in the Canon EOS mount.. they are in fact all the same, just ships with a different T-mount adapter, and the 420-1600 just ships with a 2x teleconverter.
This is a very light weight lens, especially for its focal length, it has no aperture blades, it's completely empty on the inside, its like an old style hand telescope. When sources of strong constrast/light are coming toward the camera, expect heavy chromatic aberration, free of chromatic aberration in other situations.
However, I've found a particularly excellent use for this lens, which is taking great photos of the moon on a tripod with a shutter release cable on my Canon 30D.
Although be warned, the lens is very physically long, although light, it makes focussing extremely difficult, especially on a tripod, as there is no tripod collar, you attached the camera to the tripod, then when you zoom the lens all the way (linear pull zoom) the lens is over 30cm long (12 inches!), although light because its empty, its supported on the tripod from the camera base, so soon as you touch the lens or camera, or the focussing ring, the image in the view finder shakes like crazy while trying to focus, making it hard to focus on the most useful application with this lens... on a tripod.
You can only use this lens hand held in full day light, and if you're doing so you'll need a shutter speed of 1/500 sec to eliminate blur from your own movement (due to the massive focal length), 1/250 sec is the minimum for sharp shots I could personally get.
And shooting in daylight, whether hand held or tripod, you're going to want to use a 1A sky filter AND a polarising filter (or at least one of them) to increase colour and contrast, luckily this thing comes with a lens hood.
The top of this lens screws off easily, so you can keep the lens pieces clean, if they ever develop fungus, good thing about this lens is water wont damage it, as it doesnt even have aperture blades, just glass and coated metal.
Though since the tip screws off you could cut a circle out of some black card then a hole in the middle and insert it into the middle of the lens to create your own aperture to try and improve sharpness and increase depth of field, and reduce aberration and flare etc.
I hope this helps.
Also, forgot to mention that this lens has pretty good macro capabilities (in terms of enlargement in close focus objects with miniscule depth of field).
