Say, Trimagon 90/2.6 has superior rendering and OoF compression (bohkeh) to any 85/1.4 of today, and it keeps that look when 'nifty' 85mm loses all charm. Aperture conversion by stops of equivalence (say between FF and APS-C sensors) is futile experiment and a false science, because each lens can be made to deliver unique OoF look at any aperture. There is no 'look equivalence' between formats. Here are the final photos, sans YouTube compression and in a higher resolution so you can compare for yourself: Of course, the smaller in sensor size you go, the greater the chances the noise in low light may become significant. And that's where, predictably, the full-frame shots pull ahead with more subject isolation (and lower noise which you may or may not appreciate depending on viewing size).

When it came time to shoot at night, Manny had to change tactics a bit and shot the A9 photos with the G Master almost wide-open at F1.8 to avoid having to crank the ISO too high. The bokeh was better on the GM though, as the Zeiss FF/1.8 is known to have onion-ring bokeh (with green/purple fringing). It's no surprise then that the images had roughly the same subject isolation, since Manny shot at equivalent apertures. To try and match depth of field, Manny shot the A9 photos at F2.8, and the A6500 photos were taken wide open at F1.8, at least for the daytime photos. Now that these two things are out of the way, click play up top to watch Ortiz' 'real-world comparison' between the full-frame A9 with an 85mm F1.4 G Master lens, and the APS-C sensor A6500 with a Zeiss 55mm F1.8.

Most people agree on this definition and that's good enough for our purposes, but by all means feel free to gripe about it.

Full-frame has been arbitrarily defined as 'a sensor the same size as a frame of 35mm film'.

Test charts and studio scenes do not exist in some alternate dimension where the laws of physics are suspended-they, too, are 'real world' tests. Every comparison is a 'real world' comparison.He simply went out shooting with his wife/model Diana and two different Sony cameras-the full-frame Sony a9 and the crop sensor Sony a6500, both 24MP-to see if he could tell a significant quality difference between the two after a portrait shoot. You can read our more technical take on sensor size hereĪs usual, Manny's take is a bit more down to earth and less tech-focused than we tend to go.
