Tamron 15-30mm f/2.8 Di VC USD teardown

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.

He writes:

[…] 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.

Canon EOS M3 review (much faster AF, excellent image quality)

Canon eos m3

Photography Blog reviewed the Canon EOS M3. In the conclusion:

[…] the EOS M3 is […] a good camera, and if you already have a number of EOS lenses, it’s a logical choice if you want to reduced the size of the overall system. With the addition of a much faster AF system, control and exposure compensation dials, bigger handgrip and a tilting LCD screen, more experienced photographers will find much to like. It really does need an integrated viewfinder, though – the days of buying an expensive EVF that takes up the flash hotshoe are long gone when all of the EOS M3’s principal rivals have one built-in, in a similar body size and at the same price-point. In terms of image quality, the EOS M3 happily fits the bill, with the new 24.2 megapixel sensor delivering very pleasing images throughout the ISO range.

As usual with EOS M3 reviews, the lack of native lenses is criticised. Read the full review at Photography Blog.

Yet another Yongnuo 35mm f/2 review

Another review of Yongnuo’s budget lens, the 35mm f/2, by Shooting on a Budget. In the conclusion:

The autofocus in video has improved since the YongNuo 50/1.8. With that lens, the autofocus would hunt, but fail to catch. In this, it’s slower than the Canon, but it works somewhat. It will zip close pretty quickly, but then takes a handful of zips back and forth to finally catch, about 2 seconds worth.
