- I think the single greatest advantage to digital cameras are the ability to review the image in the field. When using film, you gotta wait 'til you get back, you get it developed to really see what you have, but with digital, it's all here. There's never an excuse to say, "Oh I exposed improperly," or "It's not sharp," you have the feedback. So let's take a look at how that works on the Sony. We're gonna go ahead and take an image. So what we'll do is, bring it up here, we're going to use back button focus, there's my confirmation.
I'm going to take a shot with the remote shutter, and that image is going to hold on my screen for 10 seconds, and before it goes away, I'm going to hit the C3 button, which is the magnification tool, and it's gonna go ahead and zoom in, and right away I see, magnified, what it is that I just took, and I can move the directional pad up, down, side-to-side, all around, and what often happens is, is I'm a little bit too tight, and I'm not sure where to go, I can use the wheel to go in and out, and I'm gonna check corner to corner and make sure everything's sharp.
Now my aperture was f/2.8, which means where I focused is razor sharp, but you immediately see nice softness behind it, so this is a macro lens and that's gonna happen when you're shooting at f/2.8. So this is just a wonderful, simple way to review your image. Now, this is one of the beauties of an EVF, is, oftentimes, when you see me with a DSLR, you almost always see me with a Hoodman loupe, and what the Hoodman loupe does, is it enables me to cover the screen, to block all the peripheral light, especially on a bright, sunny day, and really study the image.
But with an EVF, all you have to do, is put your eye right up to the camera, when you do that, what you see on the back of the screen, you will see in there. So on the brightest of days, all you have to do is look in that EVF, and it completely eliminates the need for a loupe. Now, when checking for sharpness, that is how I do it, and that's how I recommend you do it. Really look, put your eye up to that eye piece, zoom in, zoom out, move around, and make sure you're 100% satisfied that it's sharp.
