It's still not as impressive as it used to be. Not as sharp as the (very expensive) SMC FA 2.8/28-70mm. Yes, I agree. If I could afford the FA 28-70 mm 2.8, no doubt I would have bought it. But it is a question of getting what you pay for. Anyway, my Tokina is an excellent lens for the price. As for flare: I don't have the original tulip shaped lens hood anymore. I droped it in the sea from a chopper sometime ago. I use a metal hood, I got from a water damaged, later version. I think it's not quite as effective as the original hood. At 28mm the front element is almost at the front of the lens barrel. I guess there's not much flare protection at 28mm. You are right. The original hood is to shallow to provide adequate masking at 28 mm.

I'm afraid now it is too cold and windy in town to go to the nearest swimming pool and shoot some frames ;-) Seriously, the only test I have performed in the last few years has been a series of shots of an IT8 target with a pair of different films, in order to build an ICC profile of those films to use such profiles with Vuescan. Previously, I also shot a resolution target to see what was the real resolution of my Epson scanner, but I haven't returned to that scientific path since.

Thats like buying a car with its only disadvantages being a wimpy engine and a bad suspension... Every 24-to-something or 28-to-something I've had or used showed more distortion than a 24 or 28 prime. It is something you have to live with when using a wide to tele zoom. And all non Pentax lenses I have used have shown worse coatings than SMC.

The distortion may not be a problem in a lot of shooting situations (landscapes and the like), and he did say flare prone compared to an SMC lens, which are generally not very flare prone. Barrel distortion is a problem with a lot of zooms, one just has to be aware of it and not put the lens in a situation where it will fail. Zooms are like that, everything is a compromise. Flare is an issue that can often be solved with a lens hood. William Robb

Yes, he said the lens was more flare prone than a SMC lens. One would have to assume under same conditions. Either both using hoods or both not using hoods. If his comparison was with hoods, then adding one didn't help did it? If the comparison was without hoods my point is yes, adding hoods may help but lenses that are worse without hoods also almost always tend to me worse with hoods too as image light can and does cause flare too and hoods don't help that.

Yes, I said the lens is more flare prone than SMC lenses. I have not run comparison tests, as I don't waste my time in that kind of things. What I mean is that after hundreds or even thousands of shots with the Tokina ATX Pro II 28-70 2.6-2.8, Pentax FA 28-70 4.0, FA 28-80 3.5-4-7, F 35-70 3.5-4.5, F 35-80 4-5.6, and Tamron SP 24-135 3.5-5.6 AF; I found that the Tokina, in contre-jour shots or with the sun in the frame or near the border of the frame, flares more than the SMC Pentaxes and also a bit more than this particular Tamron lens, and the Tamron coatings are not equal to the ones on Pentax lenses, too, although marginally better than the ones applied to this Tokina lens. I think this is not a great surprise, as I have seen the same thing to be true when comparing Pentax lenses to Nikon or Canon objectives. Once said that, I think that the Tokina is an excellent, sharp and well built lens, but these 28-70 or 28-80 2.8 zooms can't surpass the performance offered by the best primes, they always show bigger geometric distortion. This Tokina is almost as sharp as a prime. As William said, in most cases the barrel distortion of this lens, which is gone at the 35 mm. setting, is not apparent.

I'm saying that unless the poster has specified that he has made a formal test, you can't presume that he has. Well, I suppose you can, and have. It is entirely possible that he has come to the conclusion that one lens is a bit more prone to flare as a general impression made by shooting with both lenses in a variety of situations over a period of time, and finding that one lens is more flare prone than another one by looking at the resulting pictures. It happens that way, and the statement can be just as valid as a conclusion from a formal test. Quite often, a photographer who is not visually challenged, can make some pretty valid observations by using the equipment for taking pictures. I expect you won't give this much credence. Unless the original poster steps up and indicates how he has concluded that one lens is more problematic than another, neither of us know what, if any, his test procedures involved. Of course now that the famous JCO may have declared him dumb, he may not want to. William Robb

RE: Arghhh.... My Tokina AT-X ProII 28-70mm sucks big time (Lens test results) !!
I'm not complaining :-) The chopper, my colleaque and the pilot. My colleaque was using a Canon G5. His results were amazingly sharp http://gallery46369.fotopic.net/p7414129.html One of the shots i took with my faulty Tokina lens: http://gallery46369.fotopic.net/p7414128.html Jens Bladt mailto:[EMAIL PROTECTED] http://hjem.get2net.dk/bladt -Oprindelig meddelelse- Fra: Don Sanderson [mailto:[EMAIL PROTECTED] Sendt: 15. november 2004 00:05 Til: [EMAIL PROTECTED] Emne: RE: Arghhh My Tokina AT-X ProII 28-70mm sucks big time (Lens test results) !!

I managed to fix one problem: For some time I couldn't shift the focus clutch to Auto Focsus, causing the focus ring to move during auto focusing. Below the rubber on the focusing ring, I found a loose screw (part of the clutch mechanism). After tightening this the clutch works right again. But the lens still don't focus at infinity at 28mm. It's probably the bayonet, that's not quite straight after my fall/repair. I may try to get the bayonet replaced. I did some quick tests - and now it seems to have improved to the same performance as the Tokina 2.8-4.3 28-70mm at 28mm and still much better at 70mm. It's still not as impressive as it used to be. Not as sharp as the (very expensive) SMC FA 2.8/28-70mm. As for flare: I don't have the original tulip shaped lens hood anymore. I droped it in the sea from a chopper sometime ago. I use a metal hood, I got from a water damaged, later version. I think it's not quite as effective as the original hood. At 28mm the front element is almost at the front of the lens barrel. I guess there's not much flare protection at 28mm.

I have this lens, and I also had the F 35-80 4-5.6, until I sold the latter last January, and the Tokina is sharper. In fact, it is very sharp for a zoom lens, its only disadvantages being noticeable barrel distortion at 28 mm. and that it is a flare prone lens, compared to SMC Pentax lenses. Tokina must have put a multi-coating that is not as good as Angenieux's on its lens as the Angenieux father lens is said to be very good against flare. Andre
