Landscapes and 24mm

Hello to all of you !

I'm a newbie, and already have lenses questions...

When I'm shooting landscapes, I have my Sigma 10-20mm, but it sometimes is too short, and the image quality at 20mm is not exceptionnal...

I have my DA 35mm Ltd. The image quality is excellent but it is often too long...

I have the 18-55 zoom, but I don't liek it so much...

I would like to shoot landscapes pictures around 24mm and I'm searching for the perfect lens for it !

I know that the Zeiss are great but too expensive for me...

There are the Skopar 20mm and DA 21mm Ltd, but maybe a little bit short.

What would be the best solution around 24mm (about 200 euros) ?
The old manual Asahi 24mm / f2.8 ?
The Takumar SMC 24 mm / f 3.5 ?
Sigma 24mm f2.8 super wide angle II ?

If you tell me that my 18-55 zoom is better at 24mm that both lenses above, of course, I will go back to my 18-55mm...

I don't see so many prime lenses around 24mm or 25mm, maybe the best solution would be a zoom like DA 17 - 70 mm or 12 - 24 mm (more expensive)...

What do you think about all that ?

Thanks for reading all this, and for all your answers / ideas !!!

You can try to go to a manual lens that would be sheeper or streatch a bit more and get DA21 and you get two in one, landscape and also street.
You can always perform a small adjustment crop on image and get the 24mm look you like.

Only my 2 eurocents.

have you looked at the test charts for your current lenses to make sure your shooting at the optimum f stop for them?

Id probably have to suggest the only real lens that can improve your iq would be the FA 31 limited. Since the DA35 is pretty good

Or perhaps the sigma 30 1.4? dont know much about that lens personally though.

You could also be stitching together panoramic shots from the 35.

I don't know any of those lenses in particular, but I can say that my 18-55 II at f/8 or f/11 - where I shoot msot landscapes - is very, very close to as good as my M28/2.8. I'd be kind of surprised if many inexpensive older 24mm prmes - which would have been ultrawide on FF and hence would possibly have required design compromises - would beat the 18-55II by any noticeable amount at all.

The DA16-45 would be the generally recommended inexpensive upgrade for wide-normal landscape shooting.

People say I am nuts but it's the main reason I bought the 12-24 over the 10-20, 24mm is very handy sometimes.

I love the 24mm perspective for landscapes and as a general walk-around lenses. I was in fact looking through the offerings yesterday to see whether there are any smaller primes than my FA*24/2, and there aren't many choices. I think Pentax needs to introduce a new lens at 24mm and be very compact.

Is the A 24/2.8 the same optical formulae as the M version, or is it better ?

I don't know offhand, but the two sites I'd always check for info on old K-mount lenses are:

Personally, I doubt there is a decent prime of 24mm. Da 12-24 or Da* 16-50 could do a good enough job but their colour rendering are not in keeping with the standard of limited.

Fa* 24mm f2 is IMHO a lens for protrait and night time photography instead of landscape application when it comes to digital camera use. The colour balance tends to imbue with yellow hue - yes, a particular problem when it comes to capture green in wilderness.

Da 21mm limited lacked that clinical sharpness look while Voigtlander 20mm tends to lean on the cooler blue tone.

Older pentax lenses are though sharp but casting that 'dirty' black dots in the colour somehow.

Sigma 10-20 is in fact a very good lens in all regards.

Nothing is wrong with my A 24/2.8 lens, or my K 24/3.5 for that matter. Both produce great results. The A24 is slightly smaller than the K24/3.5 (52mm vs 58mm filter). K has slightly more interesting bokeh, and is ultra sharp right from f3.5. The A24 at least matches it on an aperture per aperture basis, but may be a tad bit softer at f2.8. The A24 is a bit harder to mount/unmount than the K24 because there isn't as much to grab onto when locking it onto the mount. The K has those lines that provide grip for mounting/unmounting.

Not sure of what you mean by "dirty black dots" in the color?

If I remember tonight when I get home I'll post a couple examples of both. Cheers!

I love the 24mm focal length, but it is difficult to find a great 24mm prime.

I've had the 25mm Zeiss ZK Distagon, which was incredible up close and had fantastic bokeh, colour and contrast, but it's massive. Looks like a zoom, it's so big. Like all the money for the lens was used on the metal and glass!

The Sigma AF 24mm superwide also focuses very close, and has pretty nice bokeh, but I found I had to stop it down more to get the sharpness I wanted.

Having said that, I usually get by with the 16-50 at 24mm and usually stop down to f/5.6 anyway... The 17-70 is pretty much distortion free at 24mm and has great resolution there too, so it's also a good choice on paper (I've never used one though).

The 12-24 is also a great performer, as Alfisti stated already. Compared to a range like 10-20mm, having the 24mm on there is like carrying an extra lens with you. The ultra wide end is really dramatic, and the 24mm end is more like a standard wide.

Werticus' idea of Stitching with the DA35 is also a great one. Turn the camera on its side and you get the same vertical field of view you'd get with a 24. Take 3 or 4 overlapping shots and have software put them together for you (unless you don't have software).

I find it odd that you find the 10-20 lacking at 20mm. Its certainly good enough for me at 20mm and f8-f16 for landscapes.

For the 24mm primes, I really like my SMC-K 24/2.8, incredible sharpness and no slouch either.

I picked up a Cosina 24/2.8 by accident recently on ebay (got distracted and clicked the 'BID' button instead of 'close window ). I was dismayed when it arrived and looked 'plastic' and 'cheap'. So I was rather surprised that initial shots seem to show that it's pretty good at f2.8 and very sharp from f4 onwards. Flare control does seems poorer than the Pentax. So you may want to try this one out if you can get it real cheap (1/4 the price of my SMC-K24/2.8).

24mm lens

I don't have the Pentax 24mm, but I do have a Kiron 24mm, f1:2.0. I am pretty sure that this is the same as the Vivitar 24 f1:2.0. I have found that this is a very good quality lens, very good for landscapes, and with its fast aperature, equally useful indoors.

It is a very useful focal length, and I find a lot of use for it.

I recently purchased an old AF Sigma 24mm f2.8 and find it a useful length. The IQ of the lens is somewhat different (seems to have a cartoonish look to it) but I find it quite nice actually.
