Differences of Pentax/Tokina 50-135mm/2.8

Hi, saw a lot of photos with the Tokina lens:
Canon Digital Photography Forums - View Single Post - Tokina 50-135mm f/2.8
Canon Digital Photography Forums - View Single Post - Tokina 50-135mm f/2.8
Canon Digital Photography Forums - View Single Post - Tokina 50-135mm f/2.8
Canon Digital Photography Forums - View Single Post - Tokina 50-135mm f/2.8

Looking nice, photozone review for the Pentax version is quite nice to:
Pentax SMC-DA* 50-135mm f/2.8 ED [IF] SDM - Review / Test Report


But how big if the difference of the Pentax and the Tokina lens for other brands?

The Pentax got it's own coating on the front element, SDM and different shell?

Any other differences?

Is the Pentax "coat "better"? Does Tokina have something similar applied to their lenses?

Is the general experience that the lenses labeled Pentax have better performance?

The Tokina AT-X Pro 50-135/2.8 DX is 6899 SEK for Canon and Nikon.
The Pentax SMC-DA* 50-135/2.8 ED SDM is 9654 SEK.

I ever compared pictures taken with my DA*50-135mm to that taken by my friend's Tokina

They appear distinctly different

We both prefer the 'Classic' colours and the bokeh of the Pentax; and they are by vast of a margin

Overall, among the zooms, the Pentax DA*50-135mm is really one FORMIDABLE lens

The Tokina also has a tripod collar, I believe. While not absolutely critical, but if I were to get a DA* 50-135 I would surely like to have that collar. But that's me.

How could bokeh be different? :/

They had a review of the tokina to:
Tokina AF 50-135mm f/2.8 AT-X Pro DX - Review / Test Report

Oh crap, I can't find anything decent (canon) in the 30-60 mm range (except maybe some waay to expensive 1.2L glass), well, non-zooms atleast, haven't checked the zooms yet, but plenty in 80-100 (the tokina 50-135/2.8, canon 85/1.8 and canon 100/2.8 macro. But it seems like atleast one too many , I guess the tokina is easiest to throw out or replace the 100 with a 180mm macro but it cost way more )

Apologies. I don't have the technical knowledge to explain this

My opinions are made based only on physical observations of two near identical sets of photos taken with both lenses at the same location and at around the same time :ugh:

The same can be applied to the 12-24mm that my friend and I have. Regardless of all claims that the Pentax's and Tokina's are identical, the results are just so different

K, weird. Read a review of the DA* 15-50/2.8 or whatever it is and also tried to see if there existed a similar Tokina, which it of course did =P

The Tokina was 2000 SEK cheaper so similar as with the 50-135 but the Pentax had their own coating but also SDM (on Nikon the Tokina was screw-drive only) and the weather seals. All performance numbers looked the same though, so same glass but different fitting I assume. Whatever WR is worth 2000 SEK or not depends I assume.

But then I also had the review of the 77/1.8 limited opened and it looked like it could be a similar performer to the 85/1.8 from canon, which it probably was, but the verdict ended mentioning how it cost twice that of comparable Nikon and Canon glass at 750(?)-800 euro, but it does not, current prices in Sweden was around 3600 SEK which is similar as the 85/1.8 and more like 375-400 euro.

Photozone really should update that price because as of NOW it seems just as affordable. Have Pentax changed the prices of that one recently or is it something they have stopped with so the stores sell them cheaper or what?

K, weird that they are different

I looked at Tokina 11-16/2.8, Canon 17-40/4L, 50/1.4, 85/1.8, 10/2.8 macro, 65/2.8 1-5x macro. They only cost like 35.000 SEK / 3600 euro together

Cheap hobby you guys have ;D, add regular and macro flash + camera + tripod ;D

Some day I will try to find equivalents from Nokia/Pentax/Olympus/whatever an see what it ends up being there to. Though only canon got the 1-5x macro and I guess I would have to choose Tamron 90/2.8 macro instead or something such, and maybe the Samyang 85/1.4.

Of course everything would be stabilized for free .. Haven't looked at any stabilized stuff for Canon since it seems nicer to pay for speed rather than stabilization. And if speed is already high then stabilization cost a lot. Plus primes often lack IS options anyway ..

May I ask where you saw that price? In Norway, the prices are NOK7800+. Maybe I should pick up a 77 while over in Sweden. : P
