Lens costs rising??

[johndow]

Went on Onestop Digital last night to check the latest on the Tamron 17-50mm (stock and price). I was surprised to see that the price was £222 (or there abouts) compared to £205 a couple of months ago.

Also, i got a 50mm 1.8 prime in March for £55 which is now £60, and a 50-250mm two months ago for £155 which is now £172

Does anyone know why this is

Probably due to the abysmal exchange rate at the moment.
I used to buy a lot of my Pentax gear second hand off a Pentax forum for yank users mainly but lately what with the exchange rate prices have risen by roughly 15%
