Based on latest report published via CIPA for the month of April 2015, we can clearly see a boom in the sale of mirrorless and DSLR camera, the sale of DSLRs hit approx 800000 units a month to 1000000 units a month and on the other hand the mirrorless sale is also increased up 400000 units a month, the mirrorless market is growing but still it remains inferior to DSLRs in terms of sales volume and popularity. ..
