Sample Photos of Full Frame Fisheye and 43 Limited on 5D

Further to my last blog entry, here is the sample photo gallery for some test photos taken with my film lenses, the Full Frame (not with a dark circle) Fisheye Zoom F 17-28/3.5-4.5 and the FA 43/1.9 Limited on my new K-mount 135 Full Frame DSLR, the "Cantax" "K5D":-

A few more footnotes about the shooting conditions/settings as well as my observations and comments on the final image quality (for the last listed point):-

1. All pictures were taken in Large Fine Jpeg file mode at a full resolution of 12.8 MPs (4368 x 2912);

2. A -0.5EV exposure compensation was applied for most pictures (as both lenses on 5D overexposed by a half-stop most of the time - all the exposures were accurate and consistent thereafter);

3. Most samples were taken at aperture values ranged from f/4 to f/8 with the most usual used aperture at f/5.6 (and around f/5.6 for the Fisheye Zoom);

4. The K5D was able to focus at apertures not smaller than f/8 on bright objects but with best sensitivity at f/4 or faster. The focusing accuracy and hit rate are both considered to be very high (as you can actually see from the samples);

5. All uploaded pictures are down-sampled to 2048 x 1365 and saved at Jpegs at 90% quality level with Irfanview. No anything else is processed and edited, the EXIF is retained also;

6. The totally dark corners as seen in a few samples of the Fisheye Zoom on the K5D is caused by the rotated built-in lens hood for what the adapted Pentax lenses are all now rotated to the left in about 20 degrees (owing to the consideration to avoid the aperture coupler of K-mount lenses in conflict with the bottom part of the EF-S mount of Canon APS-C bodies so that the K-couplers need not to be removed but can still be adapted). As this Pentax Fisheye Zoom is of 180 degrees in the Angle of View, the original built-in lens hood is designed to be in a pedal / flower shaped rectangular form and thus the upright position is critical. I have already found out a way to adapt in the fisheye zoom with less rotation but slight modification to the adaptor is required and I shall buy another adaptor to do the modiffication shortly. The widest setting for what the full vision of the Fisheye Zoom is not blocked by its lens hood is at around 19mm (With modification to the adaptor, it can be further improved down to 18mm and thus close to the ideal 17mm with full 180 degree AOV);

7. The optical quality of the Fisheye Zoom and the 43 Limited on the 5D are both really really *Amazing*, as I surely knew that they are, for years I used them in the Pentax film age. To list a few:-

• The flare control is superb, which I have never been able to see any Canon lenses (L or not) can attain that level of flare resistance and retain image clarity with strong light source / contrast in frame. Just look at the sample on board of the boat of which the camera was pointed directly to the morning Sun (which has been burnt in the picture for that part, of course);
• The resolution is amazing and with all that Canon crispness and sharpness, accurate colours (in "Neutral" Picture Style). Clipping of colour channel(s) is minimum - just look at the red boat shots and those for the flowers;
• The corner sharpnesses are yet amazing for both lenses on 5D. CAs and Purple Fringings are minimal even for the Fisheye Zoom. There is little corner blur nor obvious vignetting neither (far better than anything produced by the DA Fisheye Zoom on any Pentax APS-C DSLR bodies (which have far too more all the above problems mentioned which are actually not found with my 5D/Pentax F Fisheye Zoom combo);
• The resolution of the FA 43 Limited on 5D, for just shooting at just f/5.6 or f/6.7 is stunning! The super ever large image file size says it all (I have never been able to see such high resolution neither with my EF 50/1.8 nor my EF 24-105/4 L)! Just inspect this sample yourself! (Of course, to get this super high resolution and image fidelity, a very accurate "AF" system is crucial);

Well, these are just the results of the magical combination and fusion of the best optics with the best DSLR body on Earth! But of course, it needed to be Full Frame at the first place! (so as to get beyond the diffraction limit of Physics first - even putting aside all those other compromised design limitations of the APS-C DSLRs)
