I don't really agree with the article in general and this attitude always irritates me:
It's a surprisingly common opinion but one I think is a load of nonsense, Sony have a long history in imaging through Konica-Minolta and their video products but more importantly, I think any cameras should be evaluated as they are not what happened in the distant past. Furthermore this article makes this opinion even more ridiculous as everything the author accuses Sony of is exactly what Canon have done in the past but worse despite their 'heritage'.
In 2013 Canon released the EOS 700D, the EOS 100D and the EOS 70D then in 2014 they released two more APS-C DSLRs with the 1200D and the 7D mk II then yet another two in 2015 with the 750D and the 760D and the 80D and 1300D in 2016. That's nine cameras in just three years while the author complains about Sony releasing ten in six years.
Other companies don't need to match Sony's relentless pace to compete nor is it a problem with technology, Sony's biggest advantage would be its sensors if they didn't sell them to other companies and indeed it's rumoured there will be a new Nikon Z series with the A7RIV sensor. The problem, Nikon and Canon have is that they've chosen to try and protect their existing DSLR market and been more cautious in the mirrorless market whereas Sony along with Panasonic and Olympus chose to abandon their existing DSLR market and put all their weight into mirrorless. It's no surprise in turn that Nikon and Canon are starting to struggle as the DSLR market stagnates while Sony, Panasonic and Olympus are prospering. Even now, Canon have chosen to launch lower featured mirrorless models rather than go all out with flagship mirrorless models to compete with Sony's best. Both Canon and Nikon could actually benefit from Sony's numerous models to take advantage of what Sony have learnt and compete straight away.
I think what frustrates me most though about this opinion is that as a consumer I'm grateful to Sony for it, each new model generally offers worthwhile upgrades but at the same time Sony don't bin the old one instead offering a wider range of cameras to suit more budgets. The development of the A7 series has largely been guided by customer feedback so they've improved the handling of the cameras, extended the batterylife, upped the EVF resolution, added two card slots (which neither Nikon or Canon chose to) etc. as well as splitting up the range to offer consumers the choice of a general purpose camera, high resolution or a high speed sports model. So while the A7, A7II, A7III, A7S, A7SII, A7R, A7RII, A7RIII, A7RIV and the A9 are a lot of different cameras all on the go at once I see it as a positive that consumers have such a wide choice offering an entry level full frame camera up to a super high resolution model with all the bells and whistles. Yet the author complains that Sony don't understand photographers or their needs despite the whole reason for such iterative releases is to improve the cameras in response to what photographers want from the cameras.
I was going to say I don't know why people are allowed to publish such rubbish but then I've read the article, read the comments and commented on it here so it's done its job.
