Nifty fifty lens conundrum...

I was wondering which 50mm prime lens outside of the limited stock opt for. It will probably be my walk around lens in the city on my k30, but which one. I have looked at the Pentax 50mm FA f1.4 and also the SMC DA 50mm f1.8 which is about 180 cheaper.

Has anybody used or own either or both? And recommend one for me. On the face of it I would say the f1.4 will be the clear winner, but I always like the underdog or less popular option, providing its a good bit of kit and value for money.

Apologies if this topic has already been debated.

The 1.8 is a great optic.

I personally have found 50mm lenses too long for a city lens on a cropped sensor. It's fine for people at distance but not up to much for buildings. What will you be shooting?

Thanks for the responses guys.

K10D I will be mainly capturing buildings, through my urban exploration, but I do like the odd candid shot too.

I toyed with the 35mm Pentax, but now thinking a 16-45 or even 10-20mm. I knew it was a conundrum..lol

The 35mm 2.4 AL would be my recommendation. Small, a useful focal length, compact, nice and sharp and cheap enough too!

50mm was the most common standard lens in the old days but unless you enjoy walking backs wards into things then I expect you'll find it too long for your requirements. One way to find out is to tape up your standard zoom to 50mm and see how you get on.

As suggested, the cheap and cheerful plastic fantastic 35mm might be a better option.
Best wishes,

Andrew

You won't be disappointed, cracking lens for the price

FWIW, I would go much wider! I use a 10-20 Sigma a lot of the time when I am in towns.
K-3 II, K-3 and a K-70 from SRS (having now relegated the K-30 /"K-50" to a backup body) , & some Sigma and Pentax lenses (and a lot of old 35mm gear!)

Although the DA 35 2.4 is a good lenses, I too wonder if it fits the bill?

A Pentax 12-24 (superb lens) or the Sigma 10-20 (no personal experience but owners seem to love it) would be more versatile. Or, for a bit of weirdness at the 10mm end, but good WA performance therafter, the Pentax 10-17.

The original posting mentioned walk around lens; which typically means the smallest and lightest lens. Guessing that knocks the Sigma 50 out of the running completely; it's by far the largest and heaviest 50

I have both, and both are wonderful but for different reasons.
Before you ask, both work on Film as well, just make sure you have a film body that controls the aperture with the DA50.

Now to the nitty gritty.

FA50 F1.4 - Heavier of course, but better build. Not much bigger than the DA50. Lens does extend with focusing. Has the focal distance in a window.
IQ? Softish wide open. I would have said soft until yesterday when I used it wide open on my K-01, it certainly not soft. Lacking contrast possibly, but easily corrected in CameraRAW. CA is mad wide open in certain situations. sometimes not. Depends on the light. Stopped down to F2.5 and beyond, this lens is sharp and then some.

DA50 F1.8 - Cheap but great. Plastic mount, yet very light. Internal focal movement meaning the lens does not extend. More contrasty wide open and better control of CA wide open. However the FA knocks spots off it from F2.5 with its contract and sharpness. Then again it is not total. There is something like the old SMC-M F1.7 about it though, a certain magic in the images. (I have the F1.7 as well)

It all comes down to what you want with the nifty. The FA has the extra 1/3 stop and in the right light gives you a magic in DOF. It also provides far superior IQ when stopped down.
On the other hand the DA50 is more contrasty wide open and better control of CA up to F2.5, but then again that is when the FA is superior. Then again it is less than half the price now, and far lighter. albeit cheaper build.

At the end of the day, If you can afford the FA, go for it. If you can't, get the DA. It is still a fantastic lens and produces wonderful images. It really is not an inferior lens to the FA, instead, just as good but has different but wonderful results.

I have the 50mm 1.8, cracking lens, and based on reviews it would be hard for me to consider the 1.4 which has not had a good press.

I also agree that a 50 mm might be a stretch for your needs as on a cropped sensor it is actually classed as a short/ medium telephoto at 75 mm when applying the 1.5 magnification factor.

However it is a nice lens (. 50 mm 1. and capable of excellent results.

Going wider is a conundrum but I have settled on the best compromise with two lenses, one is a really underrated zoom ( Pentax 18-135) and the other (Sigma 35mm f 1.4 DG ) is about to become a " legend"

I bought the Sigma 35mm f 1.4 DG ART lens recently based on incredible reviews; after a couple of weeks I would underline what the reviews say " it is astonishing" and much better suited for what you want than a 50 mm .

However, as I have said numerous times before on the forum the Pentax 18 -135 is my choice as the walk around zoom "par excellence", optically and creatively.

I just wouldn't leave the house without it, ever.

It is the ultimate all-rounder and never ever disappoints (see some of the shots on my portfolio with this lens)

The Sigma is just breathtaking for sure, as a prime, but the innocuous little Pentax 18-135 is capable of being breathtaking as a zoom; if you just use it with some thought it will surprise you.

Regardless of what my shooting plans are, which are very varied, it is always tucked in the bag.

When I am travelling light on business, it is the lens of choice , the only one I take.

Focus on John Riley's comments at the very end of his review on this little gem; it is such a great little lens.

As a closing point regarding 50 mm - I just read a review on the new Sigma 50mm 1.4 ART lens - it says , this lens is the first lens we have tested that we can't fault, it is a near perfect piece of glass. However , as I said above not the best focal length for you if you want a prime and in any event it is not yet a available in a Pentax mount like it siblings ( 35mm and 85mm)

Best of luck with your conundrum

Regards
