Yep. I sure do.

[micromacro]

I can tell you from extensive experience with Canon DSLRs that lenses designed for film use are usually disappointments when used with a digital sensor.

I agree, that's why I switched to Pentax to use old lenses on DSLR.
I do keep M42 Vivitar 20mm, love that lens, but have problem focusing manually in VF with wide lens when using that range for something else than landscape.

[NZ_Ross]

Yep. I sure do.

Excellent!!!!

Personally I am waiting for the Irix 15mm/f2.4. Manual focus, but that's not a deal breaker for me. Best of all, it has a 95mm filter thread.

It will come in two versions which are optically identical. Firefly is the cheaper one, made of simpler materials and not weather sealed.

The Blackstone is made of metal, is weather sealed and comes with a hard case, but is heavier.

They are supposed to be released "this summer".

Irix. Prepare for more

[Interspieder]

I almost bought a M 20 F4 today, but in the last moment, i decided to go for the IQ than for compactness. I'll wait for the Irix, maybe the 11mm F4 or try out the 15mm 2.4. I love the aspect, that it's going to be weathersealed.
Until this moment, i'll use my Sigma 8-16 on APS-C mode. Or maybe try the Samyang? I am really not sure

You can wait for Irix... or wait for this Monster.... also coming in K-Mount: World's widest f/2.8 rectilinear lens @ 12mm

Full review @ Review: LAOWA 12mm f/2.8 'Zero-D' lens

Samyang 14/2.8 is already very good in practical use.

K28/3.5 is excellent as well.
Cheap and sharp to the edges.












Based on Wild_Mark's evaluations, the F and FA28/2.8 are good as well

I do have a FA* 24mm f/2 and a M 20mm f/4. Both great lenses, but when I want to go wider than 31mm I want the 20mm, color and contrast is great, but it lacks sharpness in the edges and the stars from light sources are not as beautiful as from my DA 15mm or my FA 31mm. I just don't get it that there is no modern f/4-ish 20mm-ish with stunning image quality on the roadmap. The 15-30mm is optically probably what I want, but that is another kilo to carry.

+1 (and not to mention the price of the 15-30 )

Did a search in the thread and don't believe I found any info on the Sigma 18-35mm f/1.8 DC Art on the Pentax K-1 (i DID someone talking about a 17-35 sigma though, unless that was an error)
Any first hand experience? I suppose it too won't be usable at 18mm in FF mode right ?

I think we the consumers (ok.. maybe not you and me... ), got what we asked for.
The buying public is made to think fast and sharp and the result of it are the fast UWA that all companies have brought out to the market.
The downside is size, weight (though again, some portion of the market may view it as a pro)

Pentax went its own way with smallish lenses, and their reward for it has been market irrelevance.
In today's numbers based online reviews, once the spec vs spec is presented between two lenses, the Pentax has already lost out in the mind of the buyer.

So Pentax has no choice now, but to address this 'call' for sharper/faster lenses.
They did say this too in their K1 special site.

Hopefully, they find success in the FF system to eventually return to smallish primes.
Right size/performance for the job at hand, rather than spec sheet champions.

IMO, don't bother with this sort of 'make do' solutions unless you already got the lens.
Usually, the edges are not that good even if it clears the vignette.
So it makes little sense to spend on such an expensive lens to 'make do'.

There are a couple of 17-35 out there for Tamron and Sigma.
Used to be cheap and no one wanted them.
Now, I think its harder to find.

Decent lenses in the ball park of the Canon 17-40L for edge sharpness.
Thats not saying a lot of course as the 17-40L isn't known for edge sharpness.
But, it was the lens many used to capture many nice photos over so many years (even now), so edge sharpness does not always make a photo.

Man, remember when 28mm was considered wide angle? And 24mm was "wow ultra wide!" ?? Now its like "Pffft, only 14mm? What is this for, birding??"

24mm seems to have become the new 28mm.
I have mixed feels between 28mm and 24mm as my wide lens.
24mm gives a wider FOV while not having that much perspective exaggeration like wider lenses. (eg. 20mm, 14mm)
Its also easier to use in that it often can give a good enough sweep from foreground to the distance esp in portrait orientation and easier to get everything within DOF too.

28mm feels more 'normal' wide.
IQ generally seems better on most 28mm than 24mm.
Smaller, cheap too.


I live in a concrete jungle and UWA really come into great use here.
The limitations of vantage points, the inability to 'move further back', and close proximity of buildings and often the need to exaggerate the perspective make 14mm, 15mm almost essential.
