Dear moderators/site-admin,
as pointed out in this thread About my Tamron 28-200 lens - Page 2 - PentaxForums.com, it does not contribute to proper ratings, if all generations of the Tamron 28-200 are mixed together in one thread. The different versions are:
* Tamron AF Aspherical 28-200mm 1:3.8-5.6 [71D] see Google Übersetzer
* Tamron AF Aspherical LD 28-200mm 1:3.8-5.6 [Black: 171D, Silver: 271D] see: Google Übersetzer and Google Übersetzer
* Tamron AF Aspherical LD IF 28-200mm 1:3.8-5.6 Macro [Black: 371D, Silver: 471D] see: Google Übersetzer and Google Übersetzer
* Tamron AF Aspherical LD IF 28-200mm 1:3.8-5.6 [571D] see Google Übersetzer
* Tamron AF Aspherical XR IF 28-200mm 1:3.8-5.6 Macro [Black: A03, Silver A03S], 2 versions of each with different rubber see: Google Übersetzer and Google Übersetzer
* Tamron AF Aspherical XR Di IF 28-200mm 1:3.8-5.6 Macro [A031] see TAMRON | News | Introducrion of the new A031

Best regards

With the exception of current lenses, the third-party database is user-maintained. If you could create new entries for those variants which are missing, and identify reviews that are consequently misplaced, I'd be happy to move them to their respective new homes.

With the exception of current lenses, the third-party database is user-maintained. If you could create new entries for those variants which are missing, and identify reviews that are consequently misplaced, I'd be happy to move them to their respective new homes.

I have now added the 4 major generations of the Tamron 28-200, which altogether would replace the existing 28-200 entry (Tamron ( Promaster ) 171D, 271D .... 571D AF 28-200mm F/3.8-5.6 LD IF Aspherical Lens Reviews - Tamron Lenses - Pentax Lens Review Database).
The picture AF 28-200mm F/3.8-5.6 LD IF Aspherical - Pentax Lens Review Database would belong to this thread Tamron AF Aspherical LD 28-200mm 1:3.8-5.6 [Model 171D, 271D, 571D, 171A] Lens Reviews - Tamron Lenses - Pentax Lens Review Database, while the picture AF 28-200mm F/3.8-5.6 LD IF Aspherical - Pentax Lens Review Database should be moved to this thread Tamron AF Aspherical XR (Di) IF 28-200mm 1:3.8-5.6 Macro [Model A03, A03s, A031] Lens Reviews - Tamron Lenses - Pentax Lens Review Database.


Sorting the reviews is a lot more complicated:

The newest review speaks of model 571 with a filter size of 62mm - something that simply doesn't exist. Taking for granted that the 62mm are correct, then the post Tamron ( Promaster ) 171D, 271D .... 571D AF 28-200mm F/3.8-5.6 LD IF Aspherical Lens Reviews - Tamron Lenses - Pentax Lens Review Database belongs to here: Tamron AF Aspherical XR (Di) IF 28-200mm 1:3.8-5.6 Macro [Model A03, A03s, A031] Lens Reviews - Tamron Lenses - Pentax Lens Review Database
The 2nd post Tamron ( Promaster ) 171D, 271D .... 571D AF 28-200mm F/3.8-5.6 LD IF Aspherical Lens Reviews - Tamron Lenses - Pentax Lens Review Database precisely assigns pictures to different versions, but falsely assumes that his Promaster Spectrum 7 XR 28-200 is based on the 571D, which again is not correct, but it is based on the A03... So I would put this post due to the majority of pictures to Tamron AF Aspherical LD 28-200mm 1:3.8-5.6 [Model 171D, 271D, 571D, 171A] Lens Reviews - Tamron Lenses - Pentax Lens Review Database
The 3rd post Tamron ( Promaster ) 171D, 271D .... 571D AF 28-200mm F/3.8-5.6 LD IF Aspherical Lens Reviews - Tamron Lenses - Pentax Lens Review Database simply goes here Tamron AF Aspherical LD 28-200mm 1:3.8-5.6 [Model 171D, 271D, 571D, 171A] Lens Reviews - Tamron Lenses - Pentax Lens Review Database
The next one Tamron ( Promaster ) 171D, 271D .... 571D AF 28-200mm F/3.8-5.6 LD IF Aspherical Lens Reviews - Tamron Lenses - Pentax Lens Review Database doesn't indicate anything - the EXIFs of the image even make me doubt that it is a 28-200 at all.
This one Tamron ( Promaster ) 171D, 271D .... 571D AF 28-200mm F/3.8-5.6 LD IF Aspherical Lens Reviews - Tamron Lenses - Pentax Lens Review Database simply goes here Tamron AF Aspherical LD 28-200mm 1:3.8-5.6 [Model 171D, 271D, 571D, 171A] Lens Reviews - Tamron Lenses - Pentax Lens Review Database
The next one Tamron ( Promaster ) 171D, 271D .... 571D AF 28-200mm F/3.8-5.6 LD IF Aspherical Lens Reviews - Tamron Lenses - Pentax Lens Review Database shall be moved to Tamron AF Aspherical LD IF 28-200mm 1:3.8-5.6 Macro [Model 371D, 471D] Lens Reviews - Tamron Lenses - Pentax Lens Review Database
This one Tamron ( Promaster ) 171D, 271D .... 571D AF 28-200mm F/3.8-5.6 LD IF Aspherical Lens Reviews - Tamron Lenses - Pentax Lens Review Database and this one Tamron ( Promaster ) 171D, 271D .... 571D AF 28-200mm F/3.8-5.6 LD IF Aspherical Lens Reviews - Tamron Lenses - Pentax Lens Review Database clearly refer to Tamron AF Aspherical XR (Di) IF 28-200mm 1:3.8-5.6 Macro [Model A03, A03s, A031] Lens Reviews - Tamron Lenses - Pentax Lens Review Database
All other posts are unclear/ambiguous and should remain where they are - if you decide to keep the old thread. If you choose to eliminate the old thread, they probably should be moved here: Tamron AF Aspherical LD 28-200mm 1:3.8-5.6 [Model 171D, 271D, 571D, 171A] Lens Reviews - Tamron Lenses - Pentax Lens Review Database

In either case, thanks Adam for encouraging me to attempt to bring order into this issue...

A last question in this story: I do have pictures of each generation of these lenses, but I do not own the copyright of these. Shall I open a new thread and ask the community to provide the missing pictures?

That would be great- you should be able to edit the listings that you've uploaded to add those pictures, or I can take care of it. Also, if you know who took the original pictures, we could ask them for permission as well.

Will take a look at the rest of the reviews shortly. Thanks for your help!

Thanks, Adam, for reshuffling the posts and pictures. I'm still checking, what to do about more pictures, I'll let you know soon.
