  • UV filters are individual compounds or mixtures to prevent ultraviolet (UV) light from coming through. UV filters are used in sunscreens to protect skin or in photography to reduce haziness or fogginess created by ultraviolet light.

  • This is an Ultra Violet absorbing filter that helps overcome the abundance of blue in outdoor photographs. Not really necessary in digital photography as the camera's white balance system adjusts for the colour temperature of the scene.

  • This coating is a filter for the harmful UV radiation. The coating is either put on the lens or is imbedded into the lens to protect your eyes for the harmful effect of the sun’s UV radiation.

Taken to demonstrate K20D high ISO capability
taken as RAW and PP done on the PC in an effort to maximize image quality
Lens is SMC Pentax-M 35/2.0 f=5.6

This photo was posted as part of a discussion about certain compact cameras alleged ultra-high-ISO capabilities.
Please note that this picture was taken with a rather good APS-C sensor (23.5X15.6mm compared to 5.3X4 to 7.6X5.7mm used in compacts) and an old but very sharp prime lens. Also note that most compacts does not record RAW files and in-camera processing is usually inferior to that done on the PC.

Why do I write this…
Wanted to buy this lens for some time now. But living outside of the U.S eliminates any possibility of returning camera goodies due to warranties or poor performance. I actually searched through the web looking for a decent review of opinion of this lens before buying it. I was really disappointed of what I found. Either way I bought the lens. An OPTEKA .35 and wanted to write this little review for anyone on the need of some info related to this product so you don’t go through a bad experience if this lens is not what you were looking for.
First and most important. This is not a fisheye lens it’s actually a SEMI-FISHEYE lens. Something you will feel scammed at first due that it is shown as a full fisheye in Amazon and any other web page trying to sell you this lens.
In your Mail Package:
Having cleared that out, when you open your UPS package you should find an adapter for 67-52 adapter that screws directly into your camera ( I used a NIKON D40 with a 18-135 lens) and a box just like the one pictured in your sellers webpage.
In your Case
Inside of it you will find a thick material carrying hard case with a soft red interior (it used to be a pouch but this is much more durable and protects your new lens way better) when you open it, you will see, wrapped in plastic, your lens covered by two plastic protective caps. These caps are almost useless due that they fall off too easily with time. I’m pretty sure that’s why the changed the worthless pouch they used to provide with a harder case.
I was a surprised by the fact that this lens actually comes with an attached MACRO lens screwed at the bottom of the Fisheye lens itself. (they have to be together in order to work properly as a fisheye but you can easily detached to have a nice macro lens for some good ultra close up shoots. (Sorry if all fisheyes have this feature but I just found out about it :D )
The Lens itself
It’s made of metal and glass and is surprisingly heavy. It’s multicoated and manufactured in Japan.
It comes with a 52mm thread, so it screws right onto your Nikon kit lens. But you in order to get the best fisheye effect you should use the shortest focal length possible. 18mm should do well. This lens has some lack of performance with softness found around the edges, but at the same time it compensates it with a good sharp central point of focus, This problem is much more visible when you use a small aperture. Sadly flare is also an issue. A last bad feature is that EXI data (Camera settings and scene information) is redundant due that this lens is an attachment to other lenses. At the very top it comes with a filter adapter that lets you screw them directly into the fisheye.
My 2 cents.
Come on! You are not reading this in order to get only the good news about this great lens (otherwise you would’ve gone to OPTEKA’s web page or the seller itself) I’m just telling you what you should expect about a lens costing around 25$ to 35$. Which by the way it does a superb job at being what I would call the “poor’s man fisheye lens” just like the 50mm 1.8 D is to all of us. It really gives great pictures, sorry if my pictures disappoint you but I’m an amateur trying to help. Look at the pictures taken with this lens by me. No modifications or enhancements were done. Hope it helps you as much as I wanted to help me decide before buying it.
