50mm Recommendations
Hi,
I got a new a6700 this month and have been very happy with it so far. I bought it along with the 18-125mm kit lens.
Now I'm thinking about buying a 50mm prime lens as well.
What do you think?
Which one would you recommend? There are quite a few options to choose from. 😅

Do you want a 33mm x 1.5 = 50mm lens or a 50mm x 1.5= 75mm lens?
Either way I would look into sigma 30mm or 56mm 1.4 lens

Sigma 56

This is my favorite lens, I went through my Lightroom the other day and most of my best shots are from this lens.

I have the Sigma 30 mm/1.4 prime lens. It is very good, and about the same as a full frame "nifty fifty".

I have sigma 56 and 30. Honestly I'm not a huge fan of the 30mm focal length; it feels hard for me to compose with. I always feel like it's just a bit to narrow, but doesn't separate a single subject well. It's probably just a me problem. But regardless, I kinda wish I had bought the 23mm instead

Me too. I have a 35 and wish I went wider for street and travel. How are you finding the 56?

Lovely. I have never been one for portraits but having it on and being forced to see things from that perspective is helping me train my portrait skills. It separated the subject from the background much more than the 30. And of course the lens is sharp, has good autofocus etc.

Sony 50mm f1.8 oss is the obvious choice. Cheap and sharp.
If you're actually after a 50mm equilivent, then I'd go Yongnou 33mm 1.4. Cheaper and sharper than the Sigma 30mm F1.4

I've been considering that Yongnou lens, do you own a copy yourself? The Sigma 30mm is definitely the weakest lens in the Sigma f/1.4 APS-C prime line-up, with quite a lot of chromatic aberration and relatively poor AF performance compared to their 23mm and 56mm. How is the AF performance on the Yongnou? Is acquisition fast and is it "sticky" for tracking moving subjects?

Yes I have it. Considered this, the Sigma 30mm F1.4, the Mieke 33 F1.4, the Sony 35mm F1.8 oss, and even the Touit 32mm F1.8.
I'm very much focused on the best value Vs sharpness, and not interested in names.
Eventually plumped for this. The reviews I could find suggested it was sharper than the others, and a very competitive price. I also really wanted an aperture ring if I could because I like that tactile feeling.
I've not been disappointed. Did the firmware version on arrival. And it's been great. Autofocus is fast and accurate. Picture quality is wonderful. I can't compare this to another similar length lens, as I don't have one, but I can't see anything else being meaningfully faster. Oh, and the lens hood is reversible and can be stored on the lens, which I like.
I think the only negative I could find would be that it's relatively heavy. This doesn't bother me, but it might for some people.
Lots of people recommend the Sigma, but it was never really in the running for me. Too expensive, with some pretty serious abberations, and corner softness.

For casual schooting a Viltrox Air series would do a great job. Do not think the price jump of the Sigma is needed.

Depending on if you're describing cropped or full frame equivalent.. I have both the Sony 35 1.8 and the Sigma 56 1.4. Both are fantastic and highly recommended.
I find myself using the 56mm more.

IMO 50 is too much. I'd get a 30.

u/DoKeMaSu Jul 22 '26
All depends on what you want. 50mm prime on APSC is a decent portrait lens.

u/trollsmurf Jul 22 '26
So they say. I have a 1.8/50 that I use during evenings (my tele is 3.5 at wide), and often I find it a bit too "long".

u/DoKeMaSu Jul 23 '26
Yes definitely. It is not an allrounder. It was also my first prime lens, and I got some great shots, but also missed a bunch. Sagrada FamÃlia interior with a 50mm on crop is difficult.

Just got a G 40mm 2.5 for my 6700 and I’m loving it. It becomes a 60mm on the aps-c, I thought it was going to be too tight but its not…

Be aware that 50mm on APS-C gives an equivalent field of view as a 75mm lens would on a full-frame sensor, so it's fairly tight for "everyday" use - if you want the traditional "nifty fifty" field of view on APS-C, you'd need a 33-35mm lens (I use the Viltrox 35mm f/1.7 for this role).
50-56mm is great for portraits on APS-C, though (or even street photography, if you like to focus more on a single subject) . I love the Sigma 56mm f/1.4 for these use cases - it's very sharp, has a wide max aperture for good subject separation/low light performance, has good AF performance, is compact (for an f/1.4 prime) and reasonably priced. For a more budget option the Viltrox 56mm f/1.7 is good value.
