New Generation of * lenses

Ok, I just got my DFA* 70-200 f/2.8

If this lens is what is to come, from Pentax star lenses, then I am beyond pleased!
This lens was delayed...and if the sharpness and color or whatever was tweaked in that time, then it says a few things about the folks over at Pentax.

Unbelievable how sharp this lens is.
I am speechless in how optically this lens is.

Well done.
Worth every penny.
I can't believe how tack sharp this lens is.

Yup, optically the thing is pretty darn amazing. Completely blows the FA* lens out of the water.

If only that zoom ring were a little bit lighter to turn...

So, you think primes have finally lost the battle?

Size and weight are still formidable opponents

But compared to two to three primes? And how often do you need 1.4 on FF? I like primes myself, but its becoming a harder sell.

Everything I've seen from this lens looks amazing. I just don't think I could handle the size/weight for any length of time.

Well I struggled with this problem and when I worked it all out, went for the primes. Here's the comparison (UK street prices):

1849 DA* 70-200 f2.8 - 2030 grams
-----------------------

779 DA* 200 f2.8 - 825 g
459 DFA 100 f2.8 - 340g
329 DFA 50 f2.8 - 265g
---------
1567 - 1430 g.

Same apertures, wider range, cheaper, lighter. Less convenient in action of course but the individual lighter weights help a lot, and there may be questions about the DA* 200's edge quality on K-1. But ouch! That weight is what puts me off bigger wide aperture zooms. Even if adding a 55-300WR (279, 466g) as backup still ends up with the 4 lenses weighing and costing the same as the zoom.

The decision was far from clear cut but I now have the 100 DFA, 200 DA*, 300 DA* and 1.4 converter to handle my telephoto needs, much as the zoom tempted me!

I wonder how much sharper it is than the Tamron 70-200 f/2.8 and how much heavier. Also, it can't be nearly as heavy as the K1 + DFA 150-450!

I own the Tamron, and *if* the Tamron hits the correct focus, based on the what the K1/K3 tells it to stop at...as screw drive can only be *just-so-accurate*...then you get a great sharp image.
However, the DFA* 70-200 lens kills it every time and it's noticeably sharper, like crazy so.
Yes, the lens is big and heavy, but that is to be expected for a FF with f/2.8
I don't think primes have lost the battle, but something happened with this lens.
Either the engineers got better training, or they bought better equipment/calibration, or maybe they hired better lens designers?
Maybe after so many years, someone lit a fire under someone, and now we have a spectacular lens.

I am in the unhappy position of having bought the D FA* 70-200 a week ago and had it shipped to my home address (there was a short-lived unusually good deal going at the time), ... but I'm travelling and won't be home for 3 weeks! So it's sitting on my desk at home but I've not laid eyes on it yet (apart from the iPhone pics my wife took to confirm all looks correct).

A bit frustrating! I'm looking forward to trying it out on my K3 when I get home, and on a K1 later in the year. It's comforting to hear all the good reports in this thread.

If you won't be home for 3 weeks...and you're some place that is photogenic...it sounds like your wife needs to FedEx/2 Day Air or whatnot to get you close to your lens!

It's what we do as wives!

She's in Australia, I'm in Colorado. Not practical. A bit heavy to be dragging around the world anyway.

After a few weeks of wait on my uncless house, i finaly retrieve the K1 and the DFA70-200 a few hours ago, and is heavier, but (at least for me) not "that" heavy, compared to the Tamron, yes, the "barrel" is wider, but it feel more well constructed, the focus and FL rings are more stiffer than the tamron, but in size they are very similar maybe 1cm (about 1/3 inch) taller the Pentax.






I can say is, at first i feel very dissapointed about the focusing speed, i think it was very slow, then i try the tamron, WAY more faster, the i give it a try to my other lenses, 43/77/31/100WR/28-75Tamron, then the Tamron again, and finally got back to the DFA*, and i realized it was as fast as the Tamron, but i feel it slower because i cant hear it the same as the Tamron with the screwdriver, just a very subtle "hummmm".... the sound that the Pentax lens make is like hear the engine of a Electric Prius roar.... not too exciting
