ISO comparison

These are 100-percent crops from our test scene. When viewed at full size, you can see there's little difference from ISO 125 to ISO 400. The only real issue I have is that photos aren't very sharp even at its lowest ISO. Noise reduction kicks in more at ISO 800, which softens details and dulls color. There's a noticeable increase in noise and noise reduction at ISO 1600 and ISO 3200, making colors more washed out and subjects appear painterly; you'll probably want to reserve these two highest sensitivities for emergencies when you need to shoot in low-light conditions or get a faster shutter speed regardless of the results. But, as with all of Sony's cameras with Exmor R sensors, there are shooting options for improving low-light/high ISO shots, so what you see here isn't the whole story.

The 16-megapixel resolution is completely unnecessary and doesn't get you much more room to crop or enlarge. If you're looking at buying this instead of a high-resolution digital SLR, you'll be disappointed--especially at higher ISO sensitivities. That said, prints at 8x10 at ISO 800 with the lens fully extended still looked good, just soft and painterly. Overall, anyone looking for a snapshot camera for regularly making 8x10 prints or smaller or viewing on a TV or computer screen should be more than satisfied with the HX7V.

Low-light performance

There are a few ways to take low-light shots with the HX7V. In this example, I took shots using Program mode, Superior Auto, and the Handheld Twilight scene mode. All of these were taken at ISO 800. Program mode only takes a single shot, and while that resulted in more noise, it's also a bit sharper than the others. Superior Auto used a multishot mode like the Handheld Twilight, where it takes several shots and combines them into one photo with reduced noise and blur from hand shake. Handheld Twilight cleaned up the noise a bit, but the white balance is off; it performs better with outdoor scenes.

If you take a closer look you can see the differences more clearly. Regardless of method, if you're using the photos at small sizes and not heavily cropping them, all of them work well for capturing low-light subjects. However, all of the multishot modes require still subjects and shouldn't be used with anyone or anything moving.

Macro

The HX7V is a capable macro shooter, able to shoot as close as 1.9 inches from a subject. The results are a little soft when viewed at full size, but you can tightly crop them and still get a good-looking photo.

Color

Color is excellent from the HX7V. Though blues and reds may not be as accurate as other colors, they are bright and vivid. Plus, they're consistent up to ISO 800; above that, things get slightly washed out and muddy-looking.

Exposure and white balance are good as well, though highlights tend to blow out. The camera has shooting options for helping with those things, though.

Burst shooting

For high-speed continuous shooting the HX7V has a 10-shot burst setting that captures at up to 10 frames per second. Focus and exposure are set with the first shot, however, and once it's done shooting you're left waiting for the images to save until you can shoot again.

Manual mode

There is a full manual option for control over aperture and shutter speed. It's limited to two aperture settings each at the wide and telephoto ends (using a neutral density filter); f3.5 and f8 for wide and f5.5 and f13 for telephoto. There are a few more sets of stops available through the zoom range: f4-9, f4.5-10, and f5-11. Shutter speeds are adjustable from 1/1,600 to 30 seconds. It's more than you get on most point-and-shoots, so I'm not complaining; just don't buy this expecting a lot of control.

Zoom range

The HX7V's 10x, f3.5-5.5, 25-150mm lens (35mm equivalent) gives you good framing flexibility for a compact megazoom. Plus, it's a high-quality Sony G lens.

Lens distortion

Sony does an excellent job of controlling barrel distortion at the wide end of the lens and pincushion distortion at the telephoto end. I saw little to no evidence of either in my test shots. Center sharpness is good, however there is slight edge and corner softness, though not enough to be concerned.

Fringing

Fringing around high-contrast subjects was minimal, too, and only really visible when photos were viewed at full size.

Backlight Correction HDR mode

Available in Superior Auto and as a scene mode, the Backlight Correction HDR mode takes a few shots at different exposures and combines them to improve backlit subjects. On the left is a photo taken in Program mode and on the right is using this mode. While the photo on the left looks a little darker, it is more balanced and you don't lose all of the cloud detail.

Background Defocus mode

In an attempt to give users a more "pro" look to photos, there's a Background Defocus mode that takes two shots, identifies the background and blurs it while keeping the subject sharp and in focus. Recommended distance from the subject is about a foot (30cm according to what the camera says on screen) and you can set the amount of blur to low, medium, or high; this was taken at high. It works best when your subject is well in front of the background, but even then it's not always perfect. At small sizes, though, it can be convincing.

Intelligent Sweep Panorama

Sony has two versions of its Sweep Panorama mode, one regular and one Intelligent. The cameras with a Sony Exmor R sensor get the latter, which includes the HX7V. The benefit is that it does a better job of handling moving subjects.

HR Panorama

But wait, there's more! Consumers must've been complaining that the regular panorama shots from Sony's cameras were too small. Sony answered back with a high-resolution option that uses the full 16-megapixel camera resolution to produce a higher quality panorama photo. Just like the regular iSweep Panorama mode, you just sweep the camera horizontally across your scene, but this time the camera is turned vertically.

The results are better, but the final file is huge with a resolution of 10,480x4,096 and 20MB (at least for this photo). I reduced the file size so you can take a closer look.
