Sigma 18-50mm F2.8 DC DN Review: Best All-Rounder for Sony E-Mount?
There are a lot of zoom lenses for Sony E-mount cameras out there, however, not many achieve the right balance of portability, speed and cost like this particular Sigma lens does. The 18-50mm F2.8 DC DN Contemporary is a compact everyday lens which is made for travel photographers, vloggers, and everyone who is tired of switching primes all the time. This lens represents a rather unique position in Sigma's portfolio as it offers wide and telephoto angles of view in one lightweight barrel which can be left on the camera all the time. During our tests, we tried to find out how effective this lens is in portrait photography, street shooting, low light conditions and whether the constant F2.8 aperture and APS-C-oriented range are worth their name or this is just another reliable zoom lens based on popularity of the brand.

Portronics Tornado Mini: Good for Cleaning Camera Gear?
Camera sensors and lens elements require proper handling when being cleaned since improper cleaning techniques or using the wrong device may actually lead to damaging those surfaces, therefore, the primary focus of this test of the Portronics Tornado Mini was to check how it works on cameras rather than to repeat already done test of general electronics cleaning. The Portronics Tornado Mini was tested on camera bodies, lenses' exteriors and interior of a gear bag during several sessions, checking the intensity of air flow which is gentle enough to be used for delicate optics cleaning without a risk of scratching and ability to blow out dust from lens crevices without damaging lenses themselves. This test takes into account the real world impressions rather than only first day impressions. Daily use and not only demonstration shaped conclusions of this review.
Portronics Tez Mini: Good for Keyboard Deep Cleaning?
The reason why we decided to test the Portronics Tez Mini primarily on dirty mechanical keyboards was their tendency to accumulate some really stubborn dirt between and under keycaps which cannot be wiped off by regular means, thus making this device suitable for deep keyboard cleaning rather than just repeating multi-purpose electronics and car cleaning review that we had already carried out before. Thus, this review is dedicated exclusively to cleaning of a genuiney dirty mechanical keyboard which had not been deep cleaned for many months with the aim of checking how good the device is at dislodging dust and crumbs without removing each keycap separately. Thus, this review is based on genuine impressions rather than on initial first-day impression only. Genuine use, not a mere demonstration, was the basis for all conclusions in this review.

It will be our aim to provide an honest opinion based on real usage experience and not on the first-day impression alone.
