The Tamron AF 28-75mm F/2.8 Di III RXD is a new lens for Sony E mount cameras. Not only is it the first zoom lens for E mount from a third party manufacturer, it is also a completely new design exclusive for mirrorless full frame cameras.
The Sigma MC-11 adapter allows you to use Canon EF mount lenses on a Sony E mount camera, with autofocus capabilities! Officially, only the Sigma lenses are supported, but the adapter still works with most existing Canon EF lenses. You can get this adapter for just 150$ when it is on sale, so it is quite aggressively priced compared to similar products such as the Metabones adapter.
The Canon EF 200mm f/2.8L II USM is an inexpensive telephoto prime lens for full frame cameras. It has been on the market for quite a while, a little over 20 years to be more precise. Can it still convince in terms of optical performance on a modern, high resolution camera? I have tested this lens with the Sigma MC-11 adapter on the Sony A7 III.
With the FíRIN 20mm F2 FE MF, Tokina offers a very interesting wide angle prime lens for the Sony E-mount system. The lens has been specifically designed for full frame mirrorless cameras and is therefore relatively compact and lightweight compared to traditional DSLR lenses in this category.
A short review of the Olympus 25mm F1.8 prime lens for the Micro Four Thirds system.
There are many things that can be wrong with a photographic lens. Optics require tight manufacturing tolerances in order to produce high resolution images. Copy to copy variation is a serious issue, even (or especially?) nowadays. While most lenses leave the factory in good condition, a non-negligible percentage reaches the market with unacceptable optical flaws. One of the most common issues is decentering.
Since this happend to me a few times already, I decided to write a short article about it. I will first explain what decentering means and then continue with a simple procedure on how to test a lens.
IBIS is short for in-body image stabilization. It is a way of optical shake reduction to help reduce or eliminate motion blur in photos. In contrast to traditional optical stabilization, instead of moving a glass element inside the lens, the camera sensor is shifted. All major manufacturers of mirrorless cameras nowadays offer at least one model with IBIS, e.g. Panasonic GH5, Fuji X-H1, Olympus OM-D or Sony A7 series. But how does it actually work? And what does 5-axis stabilization mean?

As you may know, to compare lenses of different camera systems in terms of angle of view, the focal length often needs to be converted to an equivalent value. What about aperture and depth of field or the expected amount of noise? Are those values also comparable and if so, how?
When Sony announced the A7III E-mount full frame camera a couple months back, it was quite surprising to see that they basically packed ~95% of the features of the high-end models A7rIII and A9 into this midrange camera.
