Comparison of focus lenghts from 15 to 20mm on APSC/DX

[tb_a]

As I was too lazy to pack and store my little portable studio since yesterday, I took the opportunity to show the difference in FOV of several super wide focus lengths on my Ricoh GXR-M (APSC/DX-sensor).

As usual just resized for publication.

1. CV 15mm/5.6:



2. Zenitar 16mm/2.8:



3. SMC Super-Takumar 17mm/4:



4. SMC Pentax 18-55mm/3.5 at 18mm:



5. Super-Takumar 20mm/4.5:



The picture from the Pentax zoom was shot at smallest aperture as I don't have any possibility the set the aperture on this lens manually. All others at F11. It makes it (at least for my taste) obvious that any fish eye is looking poor against the corrected CV 15mm RF lens. Shooting distance approximately 1m. Crops would be available on request....

Have fun.
