I want to buy an entry-level SLR or a single video game. Which is better, Sony a57 or Pentax k-30? It's tangled Both are cost-effective. I hope everyone can help me analyze it.

Personally, Sony single battery is better than SLR.

Reason:

1, cancel the mirror, reduce moving parts, improve the focusing accuracy, and the focusing accuracy is less likely to deteriorate with time. Cancel the reflector, also greatly improve the speed of continuous shooting, and add the function of synthesizing multiple photos, and change the function in the mode of hand-held night view, which is very easy to use.

2, electronic viewfinder, 100% field of view, what you see is what you get, you can intuitively adjust the combination of aperture and shutter (especially suitable for novices and home customers), SLR optical viewfinder is not what you see is what you get. The LCD screen is suitable for customers who wear glasses.

3. A single battery has a COMS as big as a SLR, which ensures the imaging quality.

4. Sony's single battery is very cost-effective. In the same grade, Sony's single battery is cheaper than Canon and Nikon's SLR 1000 yuan, which is equivalent to buying another lens.

5, Sony monochrome, suitable for home use, no PS later.

6, Sony A series lens, affordable, especially several large aperture fixed focus, more affordable than Canon and Nikon!

Insufficient:

1, because of the semi-transparent technology, some people always think that the light loss of single electricity affects the image quality, but in actual use, the chip in the camera makes up for the pertinence, and the influence has dropped to a very low level, which can be completely ignored by novices and family customers. Professional photographers probably have to compare AB to find the gap.

2. Some people always say that Sony's lens group is poor, but I feel that in front of family consumers and novices, Sony's ordinary lens is not much different from Canon's EF lens, or even slightly better (Canon's red circle is good, that is, ordinary family customers rarely buy it, and Sony also has Zeiss lens and G lens). Sony's zoom and focus lenses are complete, and home use is enough! !

I recommend a57. The current Pentax machine is relatively small, and the price of Pentax lens is not cheap.
