I tried out the Tamrom 70-200 but decided to stay with my A 70-210 Macro.

Great lens too!
I've got one, and I tried it out on the K1 the other day (along with about 20 or so manual lenses). So satisfying!
I definitely love my SMC-A stable!

Without wanting to bash someone else's review, the DFA*70-200 is fantastic.

I have had it just over a month and it is *miles* better than the Sigma which preceded it. It is sharper at wider apertures, focuses better, and produces the lowest chromatic aberration of any lens I have owned.

Check out this "Single In" album on the K-3. Ignore the first few shots which were with the DA*50-135 while I was waiting for the new lens.

It's even better on the K-1:

Actually, Lloyd Chambers is an arrogant prick.
No he's not, he's just very very hard on manufacturers for producing less than top tier performing product and charging top tier money for it.

Could you provide a link to that blog post? I can't seem to find it on his website. I did find a passing mention of the lens. It was in an article on Pentax macro lenses. He commented that the 70-200mm wasn't suitable for macro work, and for that reason he didn't test it for the purposes of that particular article. In another article on the K-1, the lens is listed, but the link goes to B&H Photo.
Look under the K1 Shutter Shake section, he describes the 200mm setting as a blurry mess at f2.8 and could not develop a sharp image at even f8, possible focus shift. He has very high standards and has every right, this unfortunately has passed onto myself and although my images are much better for it, it makes me look where I should not look sometimes.

I own the Tamron 70-200. Just like on my K3, it is a little on the soft side at 2.8 on K1. However, stop it down to f3.5 or f4 and it becomes a beast in terms of sharpness. The only reason I may let the Tamron go and get the much more expensive Pentax would be for WR and possibly marginally better images at f2.8. If you are on a budget, get the Tamron and get it fast before Tamron decides to stop making it altogether. If cost is no issue, go with the Pentax. I have seen samples and reviews that are all positive.
This might be a solid option for me, as I would not use it at f2.8, only f5.6 or more.

The Pentax 70-200 weighs 3.86 pounds according to listed B and H specs. I really don't see that as an overly tedious weight. I have a Sigma 150-500, it also weighs approximately that.
It's over 2kg with hood and mount ring. This is huge weight for landscape work and bush walking, travel etc.

If I had to pick between someone like Diglloyd who makes a living with people clicking his blog or someone who actually makes a living using her gear I think I'll go with Lauren.

Maybe @LaurenOE will pop in and give you her experience.

Personally I would like a 70-200ish f/4 to keep the weight down. Or a DFA*60-250 f/4.........
Interesting review, a polar opposite of Lloyds.

I think you are right about an f4 version, it would be nice considering that the K1 is pitched as a field camera, with particular aim at landscape photography.

Thanks Rondec. I will download some of the test images. Thanks for actually offering some assistance rather than bashing another reviewers opinion. PentaxForums is a tough crowd, very protective.

I can't say that I have used the DFA * 70-200 although I will probably eventually get it. I own the DA *200 currently and the biggest negative with it is the purple fringing which can be egregious at times. Auto focus isn't great either and the biggest calling card for the DFA * lens is that it seems to have the best auto focus of the 70-200 lenses available for Pentax currently. If you don't need fast/silent auto focusing, then the Tamron probably offers most of what the Pentax lens does in a lot smaller package.

I think somebody has a Sigma 100-300mm f4 for sale in the Marketplace, which would be approximately the same size and weight as a 70-200mm. True, it's f/4 instead of f/2.8, but you also get quite a bit more reach. I've been surprised at how usable f4 is on my K-30, so it should be a a good deal better on a K-1, what with the amazing high ISO and the shallower DOF of FF. Just something to consider.
Seriously considering this, as 300 is much more usable than 70 for my uses. The 100-300 always was a good lens.

I've owned two copies (first the older and then the newer version) and both were tack-sharp and focused very quickly. I guess you could kind of look at it like a 70-200mm f/2.8 with a 1.4x teleconverter built in, but without and size/weight or optical penalties. And like I said, the f4 is very usable on my K-30, so it should be even more so on the K1.

I just posted these in another thread in regards to high ISO, but here are some pictures where I was using it indoors at a stage performance. The resolution of these pictures is limited only by my K-30's ability to resolve detail at ISO 3200, which is still very good.

These are from my daughters' ballet school performance of "The Nutcracker" a couple years ago. I shot in RAW, applied a little noise reduction, and then down-sized them to a vertical resolution of 2160 pixels (the native resolution for 4K displays), so they're still fairly large image files. With the K-1, I probably would not even have had to do anything about noise. Like I said, I'm salivating to use this lens on a K-1.

The D-FA* 70-200mm F/2.8 is very sharp at all focal lengths and CA so far has been non-existent. The colors and contrast is excellent and even the bokeh is really good. Optically, I have zero complaints about the lens. I do wish the AF speed was faster. Its not as quick to track or keep up with moving subjects as I would like. My Sigma 85mm seems faster and that is not a speed demon. The lens is big and heavy and I will be buying the grip for my K-1 just for using this lens.

If size & weight were never a factory I would chose this over a lot of prime lenses in this focal range. Optically its just as good as many primes. The build quality is definitely professional grade and it doesn't suffer from focus breathing like the Nikon. Is it better than the Nikon and Canon versions? Optically I think it is. The new Sony 70-200mm F/2.8 GM might be better, but that is $1,000 more than the D-FA* 70-200mm.

The Tamron is the best lens for the money. Its a pound lighter which show in the build quality and its not as good optically across the entire range, but it is still a really good lens regardless of the price.

The Sigma is probably the worst of the bunch. Some people might have a good copy, but this lens is definitely the weakest when it comes to optical performance. Used copies should be really cheap.

I don't have a K1 but do have an older version of the Sigma 70-200 2.8 and can tell you the focus is fast but the images has a "glow" like quality wide open and doesn't clean up until around F4.5
