Should I get A50/1.2 if I already have Voigtlander 58/1.4

I use the Voigtlander mainly for portrait and low light situations. There are some strong advocates of 50/1.2 on the forum and my LBA is calling.

Does it make sense to own both lens? What can't I already accomplish with the Voigtlander that requires a 50/1.2?

You can't brag... And that's important, you know that too right?

Or, for example, if using the Voigt 58 enables you to shoot a tight headshot in a room measuring 1meter across, you can't do the same when you are forced to do the same shot in a room that measures 45cm across! Unless you have the A50/1.2! Ah-ha!

Neither can you shoot at a slightly faster shutter speed than needed! Who knows you insisted on shooting at ISO 100 and refuse to bump it up by 1 stop just because you don't want to! Ah-ha!

That's 3 good reasons for you to own it!

To be realistic, there isn't anything that the Voigtlander lens can do that the Pentax K/A 50mm f/1.2 cannot, both lenses are excellent. The f/1.2 will allow for slightly faster shutter speeds than a f/1.4 lens will - you can also stop the f/1.2 lens down to f/1.4 for a marginal boost in resolution/contrast - but from what I have seen with the Voigtlander 58mm f/1.4 SLII on my Nikon D800E the differences between the two lenses would only be noticeable at the neutrino* level. I also use the Noct-nikkor 58mm f/1.2 ASPH on my D800E and there is a considerable difference between it and the Voigtlander - but that is because the Noct-Nikkor uses an expensive aspherical lens in its optical design and thus the lens is optimised for superior image quality at wider apertures**


Pentax K5IIs SMCP-K 50mm f/1.2

* as Michael Reichmann from the Luminous Landscape once put it "mouse nuts - really, really small"

**though image quality at smaller apertures isn't anything to write home about, these lenses sell for upwards of $6000 in Mint condition. The noct-nikkor is a bit of a rarity: less than 12,000 of them were ever made.

Of curse get it, it wouldn't be LBA if you didn't.

Honestly though, I am not sure there is anything you can't do with what you have (talking of shooting wide open thatis)

I owned VL 58 twice, and I sold it twice. There was nothing wrong, VL 58 is very good lens, I just did not feel to it. (I ended having SL1 Topcor version finally, because it is a beauty). Contrary, I kept 50/1.2 Pentax primes and used them quite often. f1.2 allows to do some very interesting effects.

But the main reason is that 50/1.2 is more versatile. 58mm is sometimes too long for normal lens (especially, on APS-C) and too short as a portrait lens due to distortion.

From usability prospective, Pentax 50/1.2 is also slightly smaller and accepts 52mm filters and hoods.

You can always buy A 50/1.2 and decide which one to keep. Both lenses can be easily sold, there is a good demand on those.

No you shouldn't. You should share the wealth, and if you buy it, give away the other to some poor lost soul, who thinks that buying a A50/1.7 or A50/1.4 too much of a luxury.
