I have asked many pros, and they ALL agree that the APS-C/EFS is only a stop-gap measure until the cost of production of 35mm CMOS sensors drops. I mean, as of right now, you can buy an EOS-5D for under $2700. I think I paid like $2000 for my EOS-20D in November 2004. If the successor to the 5D adds a built-in flash and retails for around $2500, I am going for it.

With that in mind, I can personally not justify spending over $1000 for the EFS 17-55 F2.8IS. But I will admit, it gets rave reviews. According to Photozone.de, it's one Canon sharpest lenses ever produced, even more so than the EF 50 F1.4 when stopped up F2.8! Very impressive. I even think some FF users are jealous of this lens, hence why Canon is rumoured to releae an F2.8 IS zoom lens in the EF format.

Obviously the APS-C standard won't be around forever, but it should stick around for several years. I don't think the cost of the FF sensors is dropping all that quickly, because those chips aren't subject to Moore's Law. On the other hand, when the 5D gets replaced, it should be available on the used market for $2k or less, so FF will clearly continue to spread. Even when I go that route, the 30D will make an excellent backup paired with the 17-55 f/2.8 IS (if I decide to buy it). That seems like a special lens. Besides, are the rumors of a FF f/2.8 IS lens actual rumors, or just wishing out loud by FF owners?

As more companies add IS to the body (like Sony), Canon I think will move to add IS to more and more of their zoom lenses. But true, I think a few FF owners are jealous of the combination of F2.8 and IS, hence why Canon must also come out with such a lens for the EF mount. They can't diss their really high paying customers.

The Tameron can stay at 2.8 or also do other F stops?

The aperture specified is always the maximum (widest) aperture. So this lens can do 2.8, 4, 5.6, etc...

I had the Tamron 17-50 f/2.8.. returned it cause I had issues with focusing. :/ I'll be waiting for the Tokina 16-50 f/2.8 now. My 18-200VR should tide me over as a walk around lens until I go with a 2-3 lens setup. I was gonna supplement the 17-50 f/2.8 with the 70-200VR and have that set up for my daily use.. just gonna have to wait now.

You can always send it to Tamron and they'll optimize the AF for whatever body you own... it's free, and you only pay shipping one-way. I've done that for two lenses and they've turned out perfectly.

I just picked a Tamron 28-75 2.8 alphabet soup. I love it.

Really? I didn't know. Would they do it more than once if I was to get a new body?

I did this. When I first bought my Tamron, it was indeed soft at F2.8. I sent it in and a few weeks later it came back "calibrated" to the EOS-20D body. It is now MUCH sharper at F2.8! I took a lot of test pics before and after the calibration to prove this.

The Tamron also comes with a very nice seven year waranty! Should I get an EOS-5D, I'll send the lens back again and have it calibrated to that body. All I pay is shipping one-way.
