They look like Seconds or forgeries to me

I bought one new when they came out. Didn't use the 35-70mm much due to the weight, but the FOCUS leds were great with a manual lens. Even told you which way to turn the lens. Best focusing of any manual Pentax because you didn't need much to focus on it could focus on soil or grass easily.

There is a push-on rubber lens hood for the lens, but hard to obtain. They probably all fell off and got lost. It did give you a bit more to grip for MF.

The lens isn't bad wide open.

What does the update for the k1 do ?
Just done mine and the K-1 seems a lot lighter plus no flies or wasps hanging around.

I don't do video so I won't notice any improvements in that area.

Christopher Frost is my favourite reviewer. No waffle and a FULL test with samples in 7 mins. Seems like Adam is wrong, wonder why

Looking at other reviews there seems to be a lot of problems with sample variation with this lens and a thorough test is necessary on a NEW one.

Distortion looks very severe but can be corrected.

It was Adam in this thread who said .....

14mm F2.8 ED AS IF UMC (officially FF compatible, but borderline performance)

There's a big leap in image quality. overexposed shots can easily be recovered. I've managed to pull back 5 stops once or twice. Crops are easy without much loss in quality. Higher ISO possible.

The Samyung 14mm F2.8 mentioned by Chris is a good alternative, but not reported to be FF like they say.

You mean it's a sort of fuzzy logic

£200 is around the right price. Mine is the f4-5.6 version. If you intend to use filters I'd check to see which fits each lens before buying. I don't think performance is much different although some lenses were reported to be a bit soft.

Someone posted this today taken with a k5 and sigma 10-20mm.

Some recent tests on Depressing Review by a reliable photographer showing the Pentax 12-24mm outperforming a Pentax 15mm. The Pentax 14mm is even worse

I used to have the Pentax 12-24mm and the Sigma 10-20mm. The Sigma performed slightly better by a whisker so I sold the Pentax because I didn't need the two and I have a good 18-55mm kit lens that is very good if I need to cover 20-24mm.

The K20D isn't going to do justice to any of these lenses. I would buy a SH K-5 before another lens.

The Sigma 10-20mm should be OK. If you do nightime photography the Pentax 15mm (green ring version) produces nice starbursts. but isn't really any sharper.

The Pentax 12-24mm is also a good alternative.
