Classic vs. modern lens - Asahi Takumar 50/1.4 vs. Olympus 45/1.8 (MFT)

A new comparison of one of my best older M42 lenses vs. a modern Olympus lens.

Video:

In short: the Olympus is very well balanced and has fast AF. The Asahi offers more bokeh at F1.4, but is a bit softer and glowy, with F2.8 (looks more similar to F1.8 mft) we get great details, colors and contrast.

Used to have the oly lens when I was using mft, it's nice little (tiny really) lens. It's considered the best bang for the buck in mft world

Ummmm...what is a 200% crop? A 100% crop is full resolution, pixel-to-pixel mapping.

Isn't it amazing how little we have gained in that time!!
Re the "200%" wide open of the branches - note the vertical branchlet. At the bottom of it there is a little double light mark - see on the Asahi it is a little sharper. I suspect it is the closest piece of the subject matter to the camera and the Asahi is slightly front focused onto it. This (and the wider aperture) would largely explain the extra fringing of the oof areas.

Nice comparison!

That "glow" is almost certainly caused by scratches, grease, dust, fungus, balsam degradation in the old lens.

100% crop and upscales 2x (bilinear) so people with higher pixel density screen can see something.

Right, the Olympus is one of the best lenses in the mft range. Funny enough the price is only 266€ in Euroland (including 19% sales tax) but 399€ in the US, so Olympus discovered supply and demand curves.

Ok...so you upscaled to defeat the screen resolution on Retina and similar displays. The result, of course, is to decrease per-pixel fidelity and make the two lenses appear more similar in regards to detail capture.

In regards to the wide-open comparisons, your results are similar to those found when comparing the ST/SMC 50/1.4 to a ST/SMC 55/1.8 or more recent Pentax 50/1.7 lens. The f/1.4 fast 50s tend to be softer overall than their slightly slower stablemates to about f/3.5. I would be interested in seeing how the SMC 55/1.8 measures up.

Addendum: The M Zuiko is an impressive piece of glass and has a well-deserved reputation.
