| | I'm really pleasantly surprised by the images from the 'weakest' lens, the Super Takumar 200/F4. Although it has the coated optics (not multi-coated like the 300/F4), it has a much smaller area of glass than the other two lenses, but seems to be a really strong performer. |
| | |
| | The Takumar 200/F3.5 is clearly the sharper lens of the two 200mm focal lengths and has a much larger area of glass to collect light. It's a higher quality lens with more features and heavier construction than the 200/F4 and also seems to control chroma (slightly) better. However, I really don't understand what was going on with the sudden (and sustained) brightness fall-off at F11 and above. This needs looking at. If I can work out what is causing the brightness drop-off, I have no doubt that the performance of the 200/F3.5 would remain very good at F11 and F16 and suspect somewhere in the region of F8 - F11 would be the sweet spot of brightness and sharpness. |

| | The Super Multi Coated 300/F4 is a chromatic aberration //monster//. Visible chroma is present at almost every aperture setting, though it reduces to a very trivial amount by F11 and F16. It, of course, resolves far more detail than the 200mm focal length lenses do, as well as retaining higher brightness levels as it is increasingly stepped down. |

| | All chroma removed in Rawtherapee and white, highlight and shadow balance all adjusted a little. No trace of chroma left, and a nice looking image for an old 200mm lens. Really pleased with this one; I wasn't expecting much and am happy with the outcome. |

| | Definitely a //more serious// lens than the 200/F4. Again, all of the chroma / fringing was easy to clean up in Rawtherapee. I'm sure this is capable of better performance at F11 and higher, but whether it was the conditions, or me being new to this lens, it just didn't work out this time. |
