Sony NEX-7 people samples!

For a change I thought I’d take some pictures of people using the Sony NEX-7, along with the Tamron NEX 18-200mm (review), and Sony NEX 55-210mm, (review).

This week I went out to the Ritz-Carlton Dove Mountain resort and took some snaps of the Golfers in the Accenture Match play PGA event.  My goal was to use both zooms at the maximum apertures, (mostly at the long end), to separate the subject and background, and to see how the relatively inexpensive zooms held up optically.  Also important; can the NEX-7 focusing keep up with moving subjects, and how does the jpeg processing handle textures like fabrics and skin….

Sample test crops from the Tamron NEX 18-200mm and Sony NEX 55-210mm

I took a few test sample shots using the long end of the Tamron NEX 18-200mm, (reveiw) and Sony NEX 55-210mm.  The Tamron suffers a little along the sides when zoomed in, especially near 200mm, so I wondered if the new Sony 55-210mm would be substantially better around that focal length, making it worth buying for telephoto shots, as opposed to just using the more convenient Tamron super zoom.  In the sample test crops, I’ve included the centers, mid-sections and corners, all at F/8, which is the sharpest aperture for both lenses at this length, although there isn’t much difference from F/6.3, diffraction is noticeable at F/11, mostly on the Tamron.

Although the Tamron is at a disadvantage because of the slightly shorter focal length, the centers look like they have basically the same detail.  As you move away from the centers, the Sony becomes noticeably sharper, and at the extreme corners…

Tamron 18-200mm e-mount (NEX) samples

Here are a few sample shots from the new Tamron 18-200mm F/3.5-6.3 VC lens and NEX-7.  All images are right out of the camera, standard creative style.  These samples were all hand-held, so they aren’t official.  The distances are a little long, and atmospheric issues are present.

So far, the optical performance seems similar to the Sony model, meaning the long end lacks contrast, but the short end is pretty sharp.  Focusing on the long end is spotty, just like the Sony.

Good news, the NEX-7 corrects the distortion…
