SMC Pentax-Q 03 Fish-Eye 3.2mm F5.6
supersize


Description:
This is a fisheye lens for the Pentax Q System compact interchangeable lens cameras. It does not produce rectilinear images.

This lens is part of the Pentax-Q "Unique" lens series ( as opposed to "High Performance" ) and features super-protect lens coating. No hood or filters are available. The lens mount is made of plastic. It is manual focus only and has no built-in shutter or ND filter.

If this lens is mounted on a Q7/Q-S1, the camera will switch to a mode where it utilizes a smaller part of the sensor.

Pros: Tiny.
Cons: Poor sharpness, poor focusing ring.
Sharpness: 4    Aberrations: 7    Bokeh: 5    Handling: 3    Value: 8   

160' field of view, fixed f5.6 aperture, tiny and light, pleasing fisheye effect.

Manual focus ring has very short range making focusing a bit tricky, plus unlike any other lens i know it doesn't hit infinity at the end but just before.

The fixed aperture is not very useful. No built in ND filter and no way to attach any filters.

Having to use the electronic shutter seems very restrictive, maybe i am doing something wrong but I cant seem to set the shutter speed any longer than 2 seconds.

Below average image quality, especially as the slow aperture can force you to use a higher ISO.

I would love Pentax to make an updated version as it has many negatives, but with all its problems it's still fun to use and used carefully can produce nice enough results, plus as it so small and light its no hassle to carry around.

Pros: tiny size, flare resistance, round diaphragm
Cons: need to adjust settings and focus for optimum IQ (not a surprise)
Sharpness: 9    Aberrations: 7    Bokeh: 8    Handling: 10    Value: 10   

At first I was really disappointed with IQ of the 03. Images looked soft and with low contrast.

Then after experimenting with some settings, this is what I programmed the #1 dial for (jpeg):

saturation +1, key -2, contrast +4, sharp +2

Also the focus needs to be taped-set to the first bold mark, left of center. This makes a huge difference, and is the ideal hyperfocal setting IMHO!

With the above settings in effect, under ideal conditions like in good sunlight and iso125 up to 400, it gets to within about 80-90% of an aps-C dslr comparing favorably to the Sammy 8mm FE. Also note that although the aperture in fixed at 5.6, it is has round diaphragm, so the sun looks round with no "star" effects (like you get with the mentioned Sammy 8mm!).

This is good enough for PP and really great results with the Q/03 combo. I find no "diffraction problems", just take a look the the full screen panoramics linked below - results about as good as one can expect with the Q! ::

Aerial & VR Panoramas

It's a really fun lens!

Pros: Inexpensive, small, light, and its a Fish-Eye
Cons: Manual Focus, no threads, diffraction b/c f5.6
Sharpness: 8    Aberrations: 7    Bokeh: 5    Handling: 8    Value: 8   

This is my first Fisy-Eye lens and given that its for the Q it wasn't expensive at $114 BNIB from B&H. It is a Toy Lens in all but name because its manual focus, fixed aperture, no sensor in the MF ring to tell the Q to shift to manual focus assist, etc. However, its built well and weighs nothing at 29g. The lack of MF assist is not a serious problem because its DoF is extreme. The online DoF calculator says that the hyperfocal distance is ~1ft for the 3.2mm f5.6 lens. So, for anything beyond a foot it's hard to get it out of focus, motion blur maybe but not oof.

Photozone indicates that the lens has problems with defraction because it's f5.6 on the tiny Q sensor. They did indicate that there is no major drop across the frame for this lens. I realize that there is a lot of distortion but its a fisheye and that is part of what makes it fun to use.

It has a minimum focus distance of around 10cm or roughly 4 inches. So, at less than a foot or so you have to manually focus the lens but the MF assist is helpful and the V1.1 firmware's focus peaking helps too.

Bottom line for me is that this is a fun, lets play around with it, lens. The 01 Prime is a terrific lens for sharpness and overall IQ, this lens is just for being creative and having fun - which is what the Q is all about for me.

Pros: Big fun! Cheap
Cons: Focus can be a challenge
Sharpness: 8    Aberrations: 6    Bokeh: 3    Handling: 7    Value: 9   

This lens is really fun to use and quite good, special for that price.
A normal fisheye is to expensive for me, regarding you don't use such a lens that often.
In the beginning it's not easy to focus, but that will be learned real quick.
I was amazed at the quality from the pics with this lens.
