JJC 70-300 mm LH-HA005 Lens Hood for Tamron SP Camera

Product Information

Always place your lens hood where it will be needed when you take your picture. That way it will cover any part of the lens that might be visible in the photograph. If your hood is completely fitted around the lens, you can get away with only a slight gap at the nose of the hood itself, which you can cover with your hand or a small object. If not, you can use a little cleaning cloth or something similar to cover that gap to ensure that the lens hood does not disturb the image in any way. Properly placed lens hoods make your pictures look clearer, with less vignetting and fringing and depth of field Which lens hoods are best? Conclusion This small focus error probably is not relevant when shooting video, but when shooting stills it’s best to re-focus after changing the focal length.

MTF (Modulation Transfer Function) curves describe to what extent the tested lens can faithfully reproduce contrast of the subject in images it captures. There are two types of lens hoods, a “hard” lens hood and a “soft” lens hood. The first type of lens hood covers the lens barrel from the front side with a hardened cover, also known as a “cold lens hood”. It is usually of a two-piece construction. This type of lens hoods, if fitted properly, can reduce the intensity of stray light. On the other hand, if the lens hood is not fitted properly, then stray light transmission through it can be increased, and this can decrease image quality. The second type of lens hood is a “soft lens hood”, which is often covered by a third, more flexible and softer material, with an integrated attachment ring. The soft lens hood, on the other hand, can reduce the intensity of stray light. When should I use a lens hood? To make the 300mm telephoto focal length more fun and accessible, TAMRON focused intently on designing a telephoto zoom lens that's both small and lightweight. Turning the conventional concept of a telephoto lens on its head, the 70-300mm F4.5-6.3 is only 148mm (5.8 in) in length with a maximum diameter of 77mm and a weight of just 545g (19.2 oz). This gives users the freedom to concentrate fully on shooting without worrying about lens size or weight. In addition to those wishing to pursue real telephoto shooting for the first time, the lens is also recommended for people who use cameras that have built-in image stabilization because they can leave the tripod at home. Of special significance, when paired with the APS-C mirrorless cameras, this zoom adds additional telephoto reach and while remaining comfortable to handle. Users can enjoy shooting with even higher power telephoto effects at a maximum equivalent focal length of approximately 450mm 3.

Sealing: All three lenses in this comparison have a rubber grommet at the lens-mount plus further weather-sealing throughout the construction. [+] Weight: At 577g (1.3 lb.) plus 62g for the lens hood the Tamron 70-300 is almost 100g lighter than the F-Nikkor 70-300 even before accounting for the 133g of the FTZ adapter you’ll need for the F-Nikkor. The Z-Nikkor 100-400 is much heavier at 1355g + 63g lens hood + 82g tripod foot. [+]

Lens performance differs depending upon directions. Solid lines show performance in the sagittal (radial) direction while dotted lines indicate performance in the meridional (circumferential) direction. When sharp lenses capable of delivering uniform optical performance over the entire image field are tested, MTF charts show curves plotted in good balance. Aperture ring and other control elements: The focus ring on the Tamron 70-300 can be assigned in camera to operate the aperture, exposure compensation, or ISO sensitivity – or simply switched off. This is similar to the multi-function control ring on the Z-Nikkor 100-400 but there are no other control elements/buttons/switches. The F-Nikkor 70-300 has no aperture ring but sports two switches to control focus and VR mode. [+] At the long end a 100-400mm zoom offers 33% more reach/magnification than the Tamron 70-300. To get the same angle-of-view of 400mm focal length you need to crop 1.33x into an image shot at 300mm. This would result in a reduction of resolution from e.g. 45MP to around 25MP – which might still be enough for the intended purpose. Focal ratio: All lenses in this comparison have a focal ratio which becomes smaller the further you zoom in. The Tamron 70-300 starts at f4.5 at 70mm focal length and reduces its focal ratio to f4.8 from 88mm, f5.0 from 116mm, f5.3 from 144mm, f5.6 from 175mm, f6.0 from 217mm, and f6.3 from 268mm onwards. The F-Nikkor 70-300 is a bit brighter (1/3 of a stop at the long end), same with the Z-Nikkor 100-400. [0] Price: The Tamron 70-300 costs 660 EUR (incl. 19% VAT) / 700 USD / 660 GBP. The F-Nikkor 70-300 currently sells for 600 EUR / 600 USD / 630 GBP, the Z-Nikkor 100-400 is much more expensive 3000 EUR / 2700 USD / 2600 GBP.

Repeatability (the accuracy of focus on the same subject after repeated focus-acquisition) of the Tamron 70-300mm f4.5-6.3 Di III is very good (measured 98.7% in Reikan FoCal) with no outliers over a series of 40 shots. The lens focuses in around 0.5 sec from infinity at 200mm focal length to 2.17m (1:10 magnification), which is similar to the Z-Nikkor 100-400 but a bit slower than the F-Nikkor 70-300 (on a D810).

Indicators/display: The Tamron 70-300 does not feature a distance or dof indicator on the focus ring like the F-Nikkor. The Z-Nikkor 100-400 has an OLED display indicating focal length, aperture, or focusing distance (in m or ft.) and depth-of-field. [0]Let’s compare the new Tamron 70-300mm f4.5-6.3 Di III (“Tamron 70-300” for short) to theNikon Z 100-400mm f4.5-5.6 VR S (“Z-Nikkor 100-400”) and Nikon AF-P 70-300mm f4.5-5.6E ED VR (“F-Nikkor 70-300”) which was introduced in 2015 and still can be used via FTZ adapter on Nikon’s Z cameras. As usual I’ve rated the features with a [+] (or [++]), when it’s better than average or even state of the art, a [0] if it’s standard or just average, and [-] if there’s a disadvantage. The Tamron 70-300 comes without a pouch or tripod mount but the reversible lens hood is included. Both Nikkors come with a pouch, the Z-Nikkor also has a tripod foot. [0]
