Normal... depending on what you think normal is. Probably Sigma and
Tamron are imported into the Russian Federation by two different
companies, and each sets the price differently. There are huge
differences in price on most items if you compare worldwide prices.
All Voigtlander/Cosina lenses for the LeicaM bayonet are cheaper in
Czech republic than in Germany. And the same chain imports them as in
Germany! Here, the Sigma is the much more expensive one than the
tamron, also about 70%. There is also a newer, much smaller Sigma EX DG,
it's 24-60/2.8 Haven't tried it.
Good light!
