Optically the old Tamron is fine. The new Pe tax seems to be better and the old one suffers from ca, but it is very good considering the price.
However, the AF is really slow and incredibly loud on this particular lense.
The Tamron is a very good deal (assuming it is in good working condition) if you can live with the af.

I have one question though. Since I never used 70-200mm in my life and really want to use it. I am seeing very good deals on ebay of Tamron SP A001 70-200 f/2.8 AF IF Di which is less than half the price this new HD Pentax-D FA. My question is for an amateur photographer like me who only uses his camera to take portraits of family and some general photographs while on vacation, is Tamron a better deal?
Thanks
Or you could buy the Tamron I'm selling in the marketplace :-)

If I didn't have the FA* 80-200 I would since you take good care of your gear! Previous poster should save the cash and get yours! Then he can save up for a D-FA 150-450!

Yeah, F/4 is good for portraits, unless you are one of those artiste types who likes to have the Iris of the subject in focus and nothing else.
At f/4 the background can be quite nervous even at 200 mm, unless you go for a headshot. Using f/2.8 at "typical" (between 70 and 135mm give or take?) portrait length still gives you most of the face in very good focus (with a slightly softer rendering the further you go from the lens). I do agree that an f/1.2, or even f/1.8 portrait is too much

At 200mm f4 the background will be as nervous as an 85mm at f1.7.

Yes.

Or more simple: 200mm F4 equals 50mm F1 for background separation, while offering 4x the DoF, so both eyes, nose and ears are still sharp, while the background is blurred.

To give some idea: Portrait Lens Shootout: 85mm vs. 105mm vs. 135mm vs. 200mm


And more simple for Pentaxians: Take a look at any people shots done with the DA* 50-135, which is absolutely the equivalent.

I also posted examples in comments no. 881 and 885 (pag. 59) regarding subject isolation and DOF for the same framing.

The only issue with using a 200mm f4 for portraits in my opinion, is the working distance is pretty long. I always thought that that, rather than depth of field, was why fast 85mm lenses were so popular on full frame cameras for portraiture. I don't shoot those sorts of photos as much on APS-C, but I prefer the DA *55 there for the same reason.

As far as out of focus rendering and transitions from in focus to out of focus, that is going to be lens specific and looks decent, but not necessarily stellar with this lens.

There is no such drawback with the 70-210mm f/4, which enjoys a minimum focusing distance of 95cm vs. 85cm for a typical 85mm portrait lens.

I shoot with both 85mm (the f1.4 for paid work, the f1.8 for travel and day by day use) and with 70-200mm f4. The perfect working distance in my opinion was the 135mm f2 lens. The 85 is overall better because it's suited also for indoor work and also when you shoot portraits in small/crowded streets. On the other hand I love the 70-200mm f4 lens for versatility... I often go out shooting portraits in forests or shooting models in small fishing boats and an 85mm would be too short in those circumstances...

I would not have any hesitation to recommend the 70-210mm f4 over an 85mm lens, if the photographer doesn't shoot low light or indoor most of the time.

Sure. But if you are framing someone for anything more than a head shot at 200mm, how far back will you have to stand? If you are standing at 95 cm away from your subject and shooting at 210mm you'll probably have an image with just their chin to their nose framed, which could be interesting, but not usually what people think of when they think of portraits.

Obviously since it is a zoom you could choose to shoot at 85mm and that's probably what I would do, but then it is an 85mm f4 lens you are using, not an 85mm f2.

I don't have any other example right now, but here it's the distance between me and the model (I'm the one from the right, even if it doesn't make a difference in this example ) while I was testing a Sigma 100-400mm lens.



And below is the result of me framing the model at 400mm.

1/250s, f6.3, ISO 500, 400mm

I've always wondered about this, doesn't such a distance make it difficult to communicate with your subject? If you are a paparazzi photographer, less communication is better, but for a willing model, doesn't the photographer want to be able to make suggestions without yelling? Not to mention difficulties with a lack of space in a studio or lack of control over external elements outdoors. A few years ago, someone posted on this site a full length nude portrait taken outdoors in front of some trees, using a DA 200 on a K-3, which made me wonder how comfortable the model felt standing naked outdoors with 40 meters between her and the photographer.
