The Sigma and Tamron 17-35 take filters... and are quite cheap for what they can do... might want to grab that until you can get the 15-30 with Cokins...

Other than polarizer and ND for water movement or flash balancing, what filter is essential?

Polarizer generally looks very poor on UWA because of the varying light angles resulting in odd light effects. Better results are generally available in post with no filter.

The other significant issue is that filters added to UWA lenses degrade image quality far more than on normal to tele because of the increased oblique angles of light travel through the glass. And then, you go with a Cokin - and well, that is a toy filter in the first place.

I did not have luck to find that lens, only DC (for cropped format), but never for FF. It's a great lens, although it's a bit back focusing on my K5iis wide open (not in LV).

Yes you are right it is a DC and not DG unfortunately.

I'm still shooting film, and maintain Pentax, Leica, Nikon and Mamiya systems. The K-1 will probably replace all but the Leica and is the first digital camera from any make that I think I can work with. However, I would first like to see how it performs with wide-angle legacy lenses. From what I have seen and read they do not always perform as intended with digital sensors.

This factor, and a lack of big telephoto primes with fast focus speeds for wildlife shooting is all that is preventing me from pre-ordering at the moment. I can't wait till some more tests are conducted!

I'm looking forward to trying my 24-35m and 24-50A to see how they hold up. I used to love the 24-35 on film, though it never got as much use as the old 28-105...

We'll hopefully see in a couple of months...

The Sigma 15-30mm f/3.5-4.5 might be worth a look, it is a tricky lens to find though.



It is also pretty big considering its speed.

I got my Sigma 24-70 F/2.8 HSM for less than 400. I imagine it will be great. I also got my Sigma 12-24 for under 350, again, I imagine it will be good.

I did the same re the Sigma. On my K7 it does not work with the SR, as the lens throws the SR into more or less constant motion. Hopefully this will not be the case with the K1.

The Samyang/Rokinon 14mm (also sold as Vivitar 13mm) should shine on the K-1, as it is proven to shine on Canon and Nikon full frame cameras. That is, if you can deal with the distortion.

I have a Tokina 19-35 so in case I ever am able to afford the K-1, it's not a fantastic lens but it's pretty decent up to the full frame borders from f/5.6 on. Center sharpness in my copy compares well to my DA 35 2.4 from f/4.5 on, it's that impressive. But it also has a lot of distortion at its widest FL.

I have Tokina AT-X pro 20-35/2.8 it is quite soft untill f8 at edges 20 mm(APS-C) but center is quite good from F2.8 I'll have to see how it will perform. And I have also samyang 14, so we have quite similar set up. I have tried tokina on film, and it is no prob, but also film is not so demanding as digital.

Have an FA-J 18-35, not the best of lenses but cheap.

[freerider]

Preordering or not, but I will get K-1, and I realized that I don't have any wide lens for it, only old M45 Vivitar 20mm f3.8. It's a great lens, but adding wide AF would be a plus.

If I had no wide angle lenses, I would probably save my pennies for the 15-30mm. If it's anything like the Tamron version, it's going to be a solid performer.

But because I already have a few wide angle options (8-16mm, 18-35mm, 31mm) I'm going to see what I can get out of them before I fork out for a another lens.

I thought about this subject and I think the budget solution would be using my 12-24 f4 from 18mm.
Beside that I would go for the 14mm f2.8 Samyang. This seems to be a decent lens for wide shots and astro photography (no ND Filter can be mounted as the Tamron).

I realized that I don't really need an AF in a wide angle lens because of the great depth of field it gives by design. A Samyang 35 and beyond shooting wide open in f1.4 without AF is another subject (I think I wouldn't be able to handle the MF on point at that apertures )

the samyang 14mm lens is something i'm strongly considering as well. the only thing that i'm a lil hesitant about is: 1) their not consistent copy to copy 2)no ND filters.

however, i came across this lil interesting video on youtube to put a gel on the back of the lens to act as a sort of ND filter. and because its so close, i doubt it would do much to the sharpness. maybe drop it down a notch. add 2 gels of the same color to really limit light in

Oh my... thats a good point, mate. This Gel workaround might work but I don't really like it :-/
Even a filter system like the Lee stuff won't go on this lens?

Not bad. The SFH 14 filter holder for the 14mm is less than $30 on eBay.

But the prices for big ND and CPL filters ...

I for one have just couple times wished for ND ect for my sammy 14...it is not so often thatI'd buy one of these. Have been looking for one for a couple times thou. If it was my style of shooting, I'd try composite mode on camera, or just a lens which takes filters..
