The video shows footage of the UMass Chan Medical School campus and its three graduate schools: the T.H. Chan School of Medicine, Tan Chingfen Graduate School of Nursing and Morningside Graduate School of Biomedical Sciences and includes images from the announcement of a history-making $175 million donation from The Morningside Foundation in 2021. This video has no sound.


The exterior of the new education and research building will be essentially air-tight, so installation of a sophisticated air handling system is underway to keep the building comfortable and save energy in the process.

The Sony NEX-7 was used for this review. For a better understanding of terms and methods used in this review, go here. Check out the image sharpness crops at the bottom of the page. The Sony NEX 55-210mm F/4.5-6.3 (Made in Thailand) is the first telephoto zoom lens made for the NEX system, and was introduced in late 2011. Like all NEX lenses so far, it's build solidly, has a relatively smooth zoom and manual focus action, along with a nearly silent auto-focus motor which is great for keeping focus noise out of movies. You'll also notice the 'OSS' or optical SteadyShot built into the lens. In-lens image stabilization is important as NEX camera bodies do not have sensor shift stabilization like the DSLRs and SLTs have. During my use, the OSS system worked very well in controlling camera shake, and Sony claims it has a 4 stop advantage over a non-stabilized lens of the same length. The specs for this lens says there are two aspherical, and two 'ED' elements used in the construction of the lens, see last photo above.


Fit and finish seem pretty good. The lens appears to be clad in mostly plastic, with a single plastic extension tube, however, it does have a metal mount. Focus and zoom rings have a black rubber ribbed design. So far, the only color available is silver, which of course matches other Sony NEX lenses of the same color.


Lens flare/ghosting. Good ghosting control when there are no super bright light sources inside the frame, but sun flare is strong, , see examples below. Color fringing (CA). About average, to above average control at 55-90mm, and excellent control from about 100-210mm. Some NEX cameras will automatically eliminate color fringing, but this lens really doesn't require correction at any focal length. Bokeh. Quite 'busy' at all focal lengths. Look below for sample crops. Color. Same as other Sony lenses. Close up filter. Tried a Hoya +4, doesn't work well, produces too much veiling haze. Coma. None. Regular filters cause no additional light fall-off when the aperture is fully open at either end of the zoom. Filter size is 49mm. Other Sony lenses that use 49mm filters; NEX 16mm F/2.8, NEX 18-55 F/3.5-5.6, NEX CZ 24/1.8, 30mm F/2.8 macro, 50mm F/1.8 SAM, and 28mm F/2.8. Distortion. You'll notice minor to moderate pincushion distortion at all focal lengths, check out the cropped samples below. Distortion examples directly below.


Distortion is minor to moderate pincushion at all focal lengths, but the signature is fairly simple and easy to fix with distortion sliders. Select NEX cameras will automatically fix this. Light fall-off.


Light fall-off is a little strong at all focal lengths when the aperture is fully open, but this isn't very noticeable in real pictures. Some NEX cameras will automatically remove the dark corners; it's called 'shading' in the settings menu under lens comps.


Focal length numbers carry through between apertures, which is normal. You may get slightly different numbers if you want to spend all day firing off shots and moving the zoom ring in tiny increments. Bokeh crops next.


Bokeh is 'busy' at the short end at all apertures, but smooths out when stopped down a little at the long end. Crops are from the center of the image, about 20' to 30' (6m-10m) behind the focus point.


Let's check out the close focus capabilities of this lens.Check out the 100% cropped portion of the full image. The sample shot was taken with the NEX-7 24mp camera, so don't compare it to others that were taken with 12-16mp cameras. The subject is a standard US stamp, 0.87"x 1.0" or 22mm x 25mm. Also, note the shot was taken as close to the subject as focusing allowed; in this case a long 31.5" (800mm), measured from the front of the lens barrel to the subject. This lens has decent reproduction size of 0.225x, (1:4.4) and it produced a pretty sharp close focus shot at F/8. Contrast is good, but not great. As a side note; the "1996" on the bottom left of the stamp measures a mere 1mm wide.


The Sony NEX 55-210mm F/4.5-6.3 OSS lens is relatively inexpensive, and provides image stabilization, super quiet focusing, and a useful zoom range. Considering the price point of this lens, the optical performance is generally strong throughout the focal range, especially at the long end, which is probably where most people will be using it if they have the standard kit zoom available too.


Pluses for the Sony NEX 55-210mm F/4.5-6.3; low distortion, optical SteadyShot works well, fairly quick and accurate focusing, very low color fringing, and sharpness is optimized at F/5.6-8, so you don't need to stop down hard to get sharp results. Also, as mentioned above, optical performance is very good over the entire frame at longer focal lengths, that's somewhat unusual in a less-expensive kit-type lens.


Negatives; no real negatives other than the flare issue mentioned above, but; the lens seems fairly large on a small NEX camera, and the whole purpose of the mirrorless NEX system is small size right?


If you have a travel zoom, like the Tamron NEX 18-200mm or the Sony NEX 18-200mm, and find yourself using it mostly at the long end, the Sony 55-210mm would be a much better choice if sharpness is your major concern.


At the short end, the centers and mid-sections are sharp at all apertures, although the corners remain a little soft even stopped down. Moving to 100mm, I see basically the same thing, mid-sections good, corners a little soft. At the long end, I see a pretty sharp frame all the way from the center to the extreme corners, that's pretty good performance for this type of lens. Maximum sharpness seems to be F/5.6 at the short end, and F/8 at the long end; F/11 is good at all focal lengths, but slightly soft when compared to F/8.
