Sigma 70-300mm f4-5.6 DG Macro For Nikon Digital & Film Cameras

Product Information

At 300 mm wide open (f 5.6), the Tair (f 4.5) captures more detail. The Revuenon (Tele-Ennalyt) (f 5.6) gets less. The Sigma 70-300 colours look nicer to my eye; more natural. The Sigma 75-300 APO gets less detail also, but its colours are nicer still (though possibly less natural). The Sigma 75-300 non-APO λ-2 also gets less detail; its colours more resemble the 70-300. With the 70-300, CA is apparent in high contrast OOF areas, this is the only time I notice CA. Strong light sources in the frame will cause a little flare, spreading from the light across the image centre. Typically this lens controls flare pretty well throughout the zoom range, with only feint green and amber ghosts appearing in extreme circumstances. Light sources just outside the frame cause few issues, with contrast being reduced a little in extreme circumstances. The supplied lens hood virtually eliminates this, so I would tend to leave it fitted at all times.

My copy is decent sharp at all focal lengths. I got excellent results, very sharp at 70 mm, not as sharp as my FA77 but enough. It is weaker beyond 200 mm, but it can still give acceptable results even at 300mm in good light.I have used this lens quite a bit on my K5 and I like it. I use it in situation where I need different focal for fast subjects. For example, it is very convenient in amusement parks and animal shows. The AF is very fast and pictures are ok. So, I am very satisfied with the results. This is a very average lens overall , if you can find it cheap enough it might be worth trying . In good light , and no macro , it might serve your needs well enough , certainly worth a try if your on a budget . https://www.ephotozine.com/article/tamron-af-70-300mm-f-4-5-6-di-ld-macro-interchangeable-lens-review-13028 Image Quality and colours. When it comes to image quality its Very good, its not prefect and depending on your aperture and zoom but it won't let you down.

By 135mm, there has been a slight drop in resolution, with the lens still producing good centre sharpness wide open. The best quality images are still produced between f/8 and f/11 with the sharpness across the frame being absolutely uniform at f/11. i would recomend this lens to anyone looking at a good entry level lens but there a just a couple of tiny little niggles.Used in Macro mode, this lens shines as this shot of a Southern Hawker Dragonfly in flight shows. Taken on a Canon 1D with the lens set to manual focus. 1/800sec at f/8 and ISO500

I was not expecting much from it, as I used the older one mainly with my Film Cameras, due to the A ring and FF capable. My 55-300 was the better replacement for the K-5/K-3 etc etc. These views of the local Lifeboat along with a relief boat show the versatility of this type of zoom lens. Overall. the Sigma 70-300mm OS is a good value alternative to the camera manufacturer's own offerings, providing decent enough resolution at a lower price point than independent equivalents with low distortion and decent enough resistance to flare and ghosting. Sigma lenses are popular due to their ease of use, portability and the sharp results which they capture, with a variety of focal widths to choose from. These enable photographers to choose between wide aperture prime lenses for portraits, street and documentary, or versatile zooms which cover ultra wide, standard and telephoto focal widths.The lens seems to be coated well, tire rubber from burnouts comes off well without any issues although i recommend using 2 cloths. When it comes to using this lens in general, if your camera is too light or you don't have a counterweight by using a metal tripod plate you will struggle to comfortably use this lens, I use a 230g tripod plate to counterweight the body of the camera specifically for heavy lenses like this and it works fantastic. Although if you have a light camera body even with a counterweight you might struggle as when using my K100D nothing helps counter balance the lens and i can only hold the camera for 2 minutes at a time.

The next part of the barrel has a basic depth-of-field scale marked and, again on the left, carries the switch to enable ‘Macro’ photography. The final 25% of the barrel forms the focus ring, which, in manual focus, is nicely torqued. Once switched to Autofocus, it cannot be over-ridden and becomes stiff for that reason. In normal mode, focussing can extend the lens a further 17mm. There is a red ring around the lens to denote the APO version, which is needed if you have the two lenses side by side! DxOMark provides objective, independent, RAW-based image quality performance data for lenses and digital cameras to help you select the best equipment to meet your photographic needs. If you want the highest quality stop it down to f10/f11, f8 seems to have a bit softness but wide open f4 its soft but not too bad. On Day 3 it was all about sports and how the Sigma 70-300mm F4-5.6 SLD DG Macro Lens performed during fast action. On the MacroSigma’s 70-300mm has an impressive list of features but it also calls forth the warning that if something sounds too good to be true, then maybe that’s exactly what it is. Its 70-300mm focal-length range may be more than many users will really need in an everyday tele-zoom but there is nothing wrong with having a little bit of extra power – provided, that is, nothing more essential has to be sacrificed along the way. the Sigma 70-300 fits right in and does the job i need it to do-when the light is good and you can shoot F8 or better @1000sec this lens is a great lens for budding photographers on a budget At 70 mm, my Sigma 70-300 captures more detail than my Pentax FAJ 28-80 f3.5-5.6, Pentax F 35-70 f3.5-4.5, Pentax FA 28-90 f3.5-4.5, Pentax FA 28-70 f4, Pentax F 28-80 f3.5-4.5 and Pentax FA 28-105 f4-5.6 PZ. Though I wouldn't necessarily say I prefer the Sigma to the Pentax images.
