Tamron A17NII AF 70-300mm F/4-5.6 Di LD Macro 1:2 Nikon+Motor

Product Information

Also typical for a lens of this class is that the Tamron 70-300mm f/4-5.6 Di VC USD Lens has a variable max aperture. The Tamron 70-300mm f/4-5.6 Di VC USD Lens features Tamron's Vibration Compensation technology (the VC in the name), promising 4-stops of camera shake assistance. Aside from being narrow at the long end, the 70-300's variable max aperture means that manual exposures utilizing Seals are located at the lens mount area and other critical locations to deter infiltration of moisture and/or rain drops and afford Moisture-Resistant Construction. This feature provides an additional layer of protection when shooting outdoors under adverse weather conditions. At 70mm, f/4 is available, but at 300mm, f/5.6 is the widest aperture available - a 1 stop difference - allowing 1/2 as much light to reach the sensor.

A telephoto zoom is often the first lens amateur photographers add to their kit after purchasing an SLR. The ability to reach out and bring distant subjects up close is immensely appealing, and essential for many subjects. The 70-300mm focal length range was a traditional one in the film days, covering a range from relatively short to fairly long focal lengths. In the digital world (with its smaller sensor sizes), this lens roughly translates to a 105-450mm zoom, pretty long by any standard. The Tamron 70-300mm f/4-5.6 Di LD Macro 1:2 AF is very appealingly priced for novice users, and throws in surprising macro capability as a bonus. But how did it handle our battery of tests? Read on for all the results!

Intro

Spend a little more and get something better. Even if the alternative doesn't go all the way to 300mm. Size (diameter x length): 77 x 150mm (3.0 x 5.9in.) plus 67mm for the lens hood. The F-Nikkor 70-300 is 81 x 146mm + 78mm lens hood. Add 30mm for the FTZ adapter to use it on a Nikon Z camera. The Z-Nikkor 100-400 is 98 x 222mm + 65mm lens hood. All three lenses in this comparison extend when zoomed to their longest focal length: The Tamron 70-300 extends to a maximum total length (incl. lens hood) of 277mm, the F-Nikkor 70-300 to 310mm (incl. FTZ adapter), the Z-Nikkor 100-400 to 336mm. [+] Focus accuracy issues were realized in the field - and they made evaluating VC difficult as I had to discern whether the cause of blurred shots was mis-focusing or camera shake.

At 300mm, a commonly used telephoto zoom focal length, the design delivers excellent resolution from edge-to-edge. Overall, the efficient optical construction (which also contributes to its lightweight) plus Tamron’s BBAR (Broad-Band Anti-Reflection) Coating with its well-established reputation for anti-reflection properties, combine to enable the photographer to capture extremely clear, crisp images across the entire zoom range. While the lens features an advanced design with excellent core image quality, optical performance can be enhanced even further by employing the lens correction features found on Sony cameras. This lens is very lightweight, but without feeling flimsy. The fit and finish of the materials used is good and a metal lens mount has been used, which will stand up to many lens changes.

Sealing: All three lenses in this comparison have a rubber grommet at the lens-mount plus further weather-sealing throughout the construction. [+] Combining a somewhat slow AF speed with a relatively narrow aperture means that this lens is not the best choice for sports photography. Tamron have employed an iris diaphragm with seven rounded blades for a fairly pleasing rendering of the out-of-focus highlights. Overall I feel the Tamron is an excellent choice for those looking for a budget telephoto addition to the kit lens supplied with their camera. I mostly do Nature photography and the lens as most know can become very expensive, so it's imperative to make the right choices. I expect the upcoming choices to be far more expensive than the Tamron. I have no problem with that. I do have problem with the current choices. So you have no idea of what I expect nor need from a lens nor my budget. So don't go telling me what to expect concerning features at what price.

As with most telephoto zoom lenses, the resolution drops as you zoom in, but this budget lens still holds its own well, producing good to very good resolution at all apertures until diffraction robs the lens of contrast and sharpness below f/22. Shooting at these apertures would be a creative decision though.there is always the possibility that a DSLR body might not support a (likely older) third party lens. things i hate about it are for one the rather stiff zoom ring and when it is at 300mm and MFD of 0.95m

but the relatively narrow aperture typically found in this class of lens removes low light action from its uses list. Very little effort required to move the switches - I would prefer them to be more resistant to accidental changes. To test the effectiveness of the image stabilization with the Tamron 70-300mm f4.5-6.3 Di III on a Nikon Z 7 camera body, I did a series of 140 test-shots hand-held at 300mm focal length with shutter speeds from 1/320 of a second down to 1/10 sec. I used the shots at 1/320 sec with VR=off as reference of how good my handholding was at the time of the test and Reikan FoCal did the chore of evaluating the sharpness of all shots. If you want this lens you should really consider the sigma too it's faster not so noisy and handles Even though this lens does not have a wide aperture, the relatively long 300mm focal length is still able to create aFor one 1/3 the price of the Canon 70-200 IS (L) the Tamron is surely a great buy and very highly recommended. Our image stabilization test is almost finished for this lens, which advertises four stops of improvement. missing some shots and after 2 weeks it broke down for good and wouldn't focus at all i got it repaired The optical path includes 15 elements in 10 groups, with an LD (Low Dispersion) element at the front. Tamron’s acclaimed BBAR coating is employed to minimize ghosting and flare. As with all the other lenses in Tamron’s E-mount stable, the 70-300mm has a 67mm filter thread, enabling you to use the same screw-in filters across the range. Build and handling raw and know to get rid of the color fringing via imaging tools this shouldn't really be a problem for you
