What do you do if you get back a couple of Tamron 15-30mm f/2.8 Di VC USD lenses with jammed zoom rings? You disassembly them, right? At least this is what Roger Cicala of Lensrentals does.
[…] we found that the Tamron 15-30 f/2.8 is a well built lens, but certainly not very modular in construction. Where a modular lens, such as the newer Canon lenses, separates easily into three sub-assemblies, the Tamron came apart in lots of separate pieces as shown in the picture below. And we hadn’t done anything like a complete disassembly. None of the optical elements or helicoids had been touched yet and the front barrel was still on.
Getting in and out of it is not complicated or difficult, but it’s definitely more tedious than a modular design. How does this affect you? Not at all. Tamron has a really good service department, consistently ranking high on our list. Their techs probably wish the lens was more modular (I know we do) but they’ll be able to fix it just fine.
