MTF Charts of the DFA24-70 Vs Tamron A007


They look very close, but there are minor differences, probably due to sample variation or measurement method differences.

Nice try. The "Pentax" version was announced for the same list price - $1300 - as the Tamron C/N.

In The Netherlands the current price-difference is €300 (€1,249 Pentax "optics made by Tamron" minus € 949 Tamron C/N; via CameraNu.nl). May be the Tamron has no WR etc? I assume the Pentax "optics made by Tamron" looks and feels much better than the Tamron. From marketing / cost cutting (profits) point of view I think it is Ricoh's / Pentax's best choice, because the (optical) quality of the Tamron/Pentax is excellent. I understood this will also be the case for the coming Pentax/Tamron 15-30 2.8. It outperforms Canon/Nikon original (Photozine).

That means in Romania, the Tamron is $300 dearer! :-o

The $1300 is the U.S. price - I thought it was obvious, since I used U.S. dollars? That's one market where RiceHigh's assumption was false.
In Romania, the Tamron VC is ~905 euro, VAT included - this is the "street" price. I don't know the list price for the Tamron yet, it can't be higher than in Netherlands. What I know is that I won't pay the list price; I can wait until the end of May for the anniversary discount (22%).

And by the way, I'm trying to compare list prices to list prices, and street prices with street prices - to be fair.
Though fairness is rarely seen here.

I don't understand this discussion, but may be my English is not good enough.
Some list=street prices in The Netherlands (24-70 2.8) in Euro's:
Tamron 949
Tokina 998
Pentax 1,249
Nikon 1,569
Canon 1,799
Nikon VR 2,499
So the Pentax-marketed Tamron price seems not unfair...??? given the (high) quality.

There isn't much to understand, RiceHigh is attempting to troll me.

The problem here is that we're comparing the street price for the Tamron (which was announced more than 3 years ago) to the list price for the Pentax (since the lens is yet unavailable). I don't know the E.U. list price for the Tamron, I would be surprised though if it weren't higher than the current street price.

OK I understand. You say (1) the Tamron original list price was higher / now lower and (2) the Pentax original list price is now higher and will be lower in the future. I do not know .... I expect that Premium-branded product prices (for example Pentax or Renauld) develops different than not-premium-branded product prices (for example Tamron or Dacia = low budget Renauld with Dacia badge). I expect that not-premium branded price decreases and premium-branded price increases in the future. However Tamron develops to a a premium-branded product. So may be the Tamron is (very) cheap compared to the Pentax. On the other hand I think that future second hands prices of Tamron decreases more than future second hands prices of Pentax. Example Tamron 1,000 - 800 = 200 costs for using and Pentax 1,200 - 1,000 = 200. And costs will be the same.

Comparing the current listed or street prices of different similar products is fair enough.

Btw, the Tamron version has VC, which the Pentax version lacks.

On the Pentax version, the VC would only be a point of failure. The lens is stabilized anyway.

Once again: "Btw, the Tamron version has VC, which the Pentax version lacks." - Pentax 1,249 ?1?

I think consumers have to compare the total package. So:
(1) Stabilized body (medium price) + lower priced lenses (but higher than not-premium) <>
(2) Not stabilized body (medium+ price) + higher priced original stabilized lenses <>
(3) Not stabilized body (medium+ price) + lower priced not original stabilized lenses <>
(1) < (2) >>> Pentax original lower price than C/N original
(1) > (3) >>> Pentax original higher price than C/N with Tamron
