Had a nice outing with an interesting prime that's new to me, the DA 21mm limited.

Good photos! At MFD, the DoF is the shallowest, especially if you are using a wide aperture (low fnumber due to low light). So there might be only one or two millimeters that are actually in focus and sharp. That's just the physics of optics for ya

lol you will want more lenses anyway, just get started.

Of course, FA 31mm ltd is more impressive than DA 35mm f2.4, but it costs a whole bunch more. I don't know of any newbie buying such expensive lenses at the start. We all start with affordable 35mm and 50mm primes, then work our way up as we develop our skills. And yes, FA 35mm f2.0 has a few more features than the DA 35mm f2.4. And the DA 35mm f2.8 macro limited is an amazing lens, with true 1:1 macro capabilities, but even though its price is fair, it is not cheap. DA 35mm f2.4 is the place to start. You can buy it used if you want to save a little more, but you risk getting a less-than-perfect copy. Its good to buy for a reputable source like Keh.com, Adorama, or the Marketplace on these forums.

Yes.

Yes, there is a noticeable difference between f1.8 and f2.4. But keep in mind that 35mm is wider, so you can get away with a longer shutter speed before motion blur will be noticeable, so this is not such a big low light advantage as it might seem. But f1.8 at 50mm will render a much shallower DoF and bigger bokeh blur. Big difference for portraits with shallow DoF for subject isolation, for example. Not to say that shallow DoF is something to be valued, but it is a tool that can be useful.

Different lenses might render images differently. Old lenses tend to have the classic "film" look. Some old lenses are very good even by modern standards, others are funky or have a pleasing effect despite their shortcomings. Sometimes they are so cheap that you can ignore their flaws. It comes down to what you need as a photographer. If you always rely on AF, don't buy a manual lens. If you don't want to spend time to learn about M mode, don't buy a manual lens.

Btw, there are many threads about DA 35mm f2.4 vs. DA 40mm XS vs. DA 50mm f1.8. Usually the DA 35mm gets most votes for "first prime to buy" because it has a more comfortable field of view and can be used for most everyday stuff. DA 50mm is preferred if you want artsy shallow DoF photos, portraiture, things like that. I would not recommend the DA 35mm for portraiture, at least not of just a person's face, due to distortion - faces start to look round.
DA 40mm XS has slightly higher build quality than the other two and is generally a nice lens, quite sharp, very contrasty. Basically you get the DA 40mm ltd for a much lower cost, with a couple missing features.

I'd say buy DA 35mm f2.4 and older A 50mm f1.7. A series are not fully manual, but don't have AF.
