Pentax DA*50-135/2.8 or Tamron 28-75/2.8

OK. So I've got $400 burning in my pocket and I want to get a fast zoom. I shoot portraits for friends and family (a lot of engagement photos lately) and my boys playing soccer. I've been reading about the Tamron 28-75/2.8 and most people are really happy with it but there are few complaints about quality. I've also been reading about (and drooling over) the DA* 50-135/2.8 and can only find one complaint (ghosting and flare when pointed at a light compared to kit - hilarious thread by the way and great photos). One option I have is to sell a Pentax 50-200/4-5.6 and get most of the way to a DA* and stop drinking Starbucks for a couple of months.

So, knowing that this is all pretty subjective, would you buy the Tamron now, or save your pennies and by the DA*?

FYI: If you know about the Microsoft Cashback deal you can get a 30% rebate on certain ebay purchases right now! It won't last long (sorry to sound like a used car salesman). Here is a link to the details: *EDITED again* 30% off at eBay through MSFT cashback program

Oh, and I have the 50-135 and it is great, hardly ever comes off my k100d. Colors, contrast, bokeh are awesome. Pretty sharp wide open. SDM is perfectly quiet if a little slow and it does hunt a little more in low light than the FA50 1.4. Wish I could've gotten it at 30% off but I might be in the market for the 16-50mm at that price, just gotta be sure I get a good copy. (Of course, I could always take a chance and send it to Pentax for any issues. At that price it might be worth it.)

Ask yourself if you need the length or the wider angle more - the answer to that should tell you what to get first. I say first, because you should end up with both, they compliment each other nicely

Check out This Thread (50-135) and This thread (Tammy) for image examples. Can't go wrong with either, but of course the 50-135 is higher quality. (But the Tammy rocks.)

How often do you find yourself switching between your two kit lenses? If the answer is "quite often" then, in my opinion, the 28-75 will bring more bang for the buck in terms of speed and convenience. If however you find yourself using the 50-200 more often than the kit then you're the 50-135 would be my choice as it gives you extra speed the longer focal lengths where it matters more (in general).

it really depends on what you shoot now, will shoot and how you plan to cover from 20mm to 200mm at F2.8 in total.

The range above is approximate it could be as low as 16mm and the maximum focal length is a function of what you shoot.

if you don;t need beyond 135mm, AND you plan something like the 16-50mm F2.8 int he future, then the 50-135 is OK. BUT if you plan to get out to 200mm at F2.8 (ie sigma or tamron 70-200 F2.8) you may not want any gap and could opt for someting lilke the tamron 28-75 or either of the sigma 24-60/70mm lenses.

time to plan out your lens collection I think

I guess Cameta's Sigma 24-60/2.8 EX DG is now USD ~$160 on ebay if Cameta's paypal checkout is eligible for 30% M$ cashback... now that is the cheapest constant 2.8 AF zoom ever... so go for both 24-60/2.8 + 50-135/2.8
