Given that A $\begin{bmatrix}1\\-2\\1\end{bmatrix}=\begin{bmatrix}2\\-3\\-5\end{bmatrix}$ and A $\begin{bmatrix}1\\4\\-2\end{bmatrix}=\begin{bmatrix}0\\2\\-1\end{bmatrix}$ find A $\begin{bmatrix}1 &amp;&amp; 1\\-2 &amp;&amp; 4\\1 &amp;&amp; -2\end{bmatrix}$

Not really sure how to approach this question. Help would be much appreciated :)


Question: Are DSLRs a dying breed, making now the time to switch to a mirrorless camera system?
Answer: DSLRs are certainly not going away any time soon, especially at the high end of the market - ruggedness, speed, large sensor size, and the continued availability of excellent glass will keep them around for some time. Large sensor cameras will also continue to appeal to nature photographers, as the 1.0x crop factor on the higher end models will allow them to shoot wider than APS-C, m4/3, or smaller sensored cameras, lens for lens.

That said, I believe that growth of the DSLR market will slow, perhaps even flattening, as I think there are two kinds of DSLR user - pros/enthusiasts who need specific feature sets and are willing to deal with larger size and weight, and people who want better than a point-and-shoot, who would prefer a smaller camera and get some of the benefits of a larger one (APS-C sensors, for example).

It's the latter group who will poach market share from both the DSLR and point-and-shoot market segments. Neither will be destroyed, but I believe both will lose some share.

As for me, I'm a long time SLR user, who's taking the plunge, selling his Nikon bodies and lenses, and going mirrorless (X-Pro1 when it drops). I think it will offer a compromise of features and size that will get me shooting more, because I'm carrying less. And the point is to be out there shooting, after all...
