Excellent first optical light on APS-C

On APS-C, there is not much choice for optical reporting, especially because of the coefficient 1.6 (otherwise I would have taken a direct 50 mm).

Having long hesitated between the Canon and the Sigma 30 mm (the latter is designed for APS-C only), I chose this view for the following reasons:
- Canon, guaranteeing quality;
- Optics that exactly matches its description (see transmission coefficient, perfect for this perspective, ie an f / 2, which actually opens to f / 2);
- Quality / price ratio;
- Image Stabilizer;

For now I have only been able to test indoors with flash, delighted with the result. To see what it will give to the outside without flash.

And as usual, no disappointment with Amazon, received very quickly in time and hour.
