But that doesn't stop the lens working at 1.8 - it's just soft outside the centre.
Unfortunately, even the centre isn't sharp until 2.8, with a maximum at 5.6.

I use it for autofocus snapshots, but a cheap manual 1.4 is better when you've got time to set something up.

Thank you all for your suggestions and advice For the last 2 days I've been reading reviews,comparing shots with both lenses... I've even compared the DOF at minimum apertures using DOF calculator. TBH I was looking for a reason to get the 50mm, but after these last 2 days of research, I've decided to go for the 35mm. The only reason I even considered the 50mm was the f1.8, which I thought would work better for low light photography; Something I have yet to try out. That, and the slightly better reviews of the 50mm. However, after a few of you pointed out that the 50mm is sharp at f2.8 and above (and sharpness is the main reason I'm getting a prime in the 1st place), I've decided to go for the 35mm, which really is more practical for everyday shooting.

I'm gonna pick it up next week.
Thanks again for all the help

Pick up the 50 at a later date. I have both in my walkaround bag.

They're tiny, cheap and very good - great intros to the world of primes, a Pentax strength.

Get them both, they are a steal for what they deliver and you will have a lot of fun with them.

Don't be fooled, the DA50 is sharp enough at f/1.8, for me at least, and better at f/2.8. I think you made the right choice but if you think the DA50 isn't sharp at f/2 because it is sharper at f/2.8 then I have to disagree.

Both lenses are excellent but not comparable, I believe you should make your choice based on your needs (i.e. focal lenght). but that's just me, my opinion isn't worth more than any other.

+1

It is sharp at f1.8, but the autofocus let's it down. I manually focus the lens when shooting at apertures bigger than f2.8.

It is sharp at f1.8,
Nup. See Imatest results attached, Rob.

But I'll always carry one and use it, though! :-)

Being a bit soft makes it not bad as a portrait lens, especially indoors where something like a Tammy 90 might be a little too long, little slow, and little too revealing of every blemish on the target, I mean, subject's face.

Let's dispute over what "sharp" means to different people.

I believe the 50 is the better lens, or my copy was at least - but as a first prime, 35mm is more versatile, or it is for how I shoot. Well, enough about me.. neither is a bad lens so you cannot lose!

Well, that's why numerical tests exist, Filoxophy.

But they only cut down on arguments, not eliminate them, because you can still argue about methodology, and you need to make sure the cameras underneath are the same if comparisons are required.

Well done on deciding!

And to set your mind at rest - and confirm that clackers is absolutely right with his point re: sharpness - here are a couple of images just snapped using the 50mm:

Full image (out of camera) scaled to 800px: http://i91.photobucket.com/albums/k283/pjm35/20140502-IMGP8938-fl50mm-ISO400...ps20e790de.jpg
100% crop of centre, showing fuzziness on "in focus" area and some pretty bad CA: http://i91.photobucket.com/albums/k283/pjm35/20140502-IMGP8938-fl50mm-ISO400...ps28ad6bee.jpg

Given what you wanted, the 35mm does seem a better fit, but you'll obviously still be getting a nifty 50 at some point

You didn't prove anything with your chart, I will even say that if anything you validated my argument.
You are welcome to come up with a new, more convincing one, while I'm outside taking real pictures.

Pablom, you're free to ignore Pjm1's 'real picture', my experiences with the lens (which is one I like, BTW), and independent third-party testing.


You've clearly made your mind up on the matter, but in contrast, the OP was genuinely open to information to help him make a choice.

The 35/2.4 hardly distorts at all. And the little that exists is very easy to correct.

No distortion either, though (just 0.2% for the XS, according to Photozone).

They both have a 'normal' FoV, wide enough that they're perfect for environmental portraits, shots of family or friends together, and oriented sideways, half-body length individual portraits.

But the 50 is a natural for your 'head and shoulders' from short range. :-)
