How times change...When I set out on the path of learning photography in the 1970s a 24mm was considered ultra-wide and I could only dream of affording a 20mm.....most of us had a 28mm and that was as wide as we could afford to go.

Wow, this sudden topic about wides and landscapes have really opened my eyes. And may I say pleasingly saved a few quid that is going to be put for a better use somehow .

Thank you very much for all your input on these, and sorry to the OP for hijacking the thread but it was unintentionally.

Gwyn, your idea of stitching images together sounds fantastic. Something that I knew about but had never crossed my mind that it could be put to use and probably get a better effect compared to even a wide angle image captured. And you are right, in Africa everything is so distant , and I am more prone to find a landscape with something of interest to turn it into a focal point very far rather than so close that I would need a wide angle lens.

Thank you all again .

You see, we can discuss equipment after all and benefit from it even to the point that one who is an outcast from the brand prespective still gets to learn a lot here

John, your comment regarding wide angle lenses really made me think deeper as this is something I am planning to acquire fairly soon. I am used to 18mm at the widest at the moment obviously also because that's the widest angle lens I have, mind you its a zoom and not a prime. I am about to travel to Africa for a few weeks and will be travelling a good extension of the Indian coast and was thinking I should get a wider zoom something like 12-24mm Siggy.
Wasn't it you that virtually bought all of the LHR Samsung 12-24s for £179 Amin? But forgetting to go to the one in the satellite terminal allowing me to buy mine??

Actually my 16-50 is wide enough for 99+% uses so I have to have an incentive to use the Samsung

This topic is going to haunt me for the rest of my days isn't it?

... and Yes I was the one who bought them.... and No, I didn't buy them for £179, and ... No, I did not go inside to buy it. And if I had probably I would have benefitted enough to put up with the old ghost sprouting its head once in a while to bring back the subject and I would definitely have made a full swoop and get hold of every copy of it from LHR

Deja vu. I didn't have the monies back then for a 28mm. Used a Pentax 50mm std and a Sigma 200mmf/3.5 for two years at Croft circuit. Still have the 200mm!

I thought I was pretty well sorted with 28, 35, 55, 135 and 200 SMC Takumars!

Yeah John, I remember those days 28mm 125th at F8 K64, feels nice just writing that out
When I had various 10-12-24mm Zooms I just couldn't fill the space

The 12-24 is a superb lens for capturing interesting buildings in the city, and also for camped interiors. But it's not a lens I would choose for landscapes.

Ultra wides do seem quite popular among landscape photographers, though.

Funnily enough since I got my DA10-17 I've probably taken more landscapes with that than the DA12-24, and that of course is absurdly wide.

(Eg. link link)

Though I've possibly taken more still with longer lenses.

You have an incredible knack with that 10-17mm Mhuni. Even at the extreme end, your shots make great use of the distortion without looking gimmicky (which I guess is the fear, with a fisheye).

Lovely shots!!!

I love my 10-17. John is right about having some foreground interest though and I love enhancing curves with it ..

I recently bought a Pentax 14mm prime which is cool for, err, less distorted wide stuff

Thanks Pentaxophile. The fisheye's a challenging lens to use with any subject. With landscapes the foreground can be highly problematic, as can the shrinking effect it can have on more distant objects - like JR has mentioned in reference to ultra-wides. But it's great for skies and if you place the horizon close to the middle you mitigate the distortion.

To continue with the thread hijacking... these posts from Mhuni & Smeggy have just persuaded me to stick my 10-17mm in my bag to go out to Cuba!

"I find it quite amazing that when the K7 was launched is was regarded as a good camera, all of a sudden the K5 comes along and the K7 takes a bit of a slating."

I've said before on this forum that the K-7 sensor is not a great one & that was long before the advent of the K-5.

I certainly don't see the K-7 getting a slating and rather liked it. Had it not been for the faster AF and better ISO performance of the K-5 I would have kept mine.
