As we have already pointed out in our announcement, the Nikon D750 shares quite a bit with the D610 when it comes to size, ergonomics and resolution. There are, however, some big differences in terms of autofocus performance, with the D750 employing top of the line autofocus system borrowed from the new D810 with superior ability to focus in low light. Let’s take a closer look at the camera specifications and see the differences between these cameras. Please keep in mind that this comparison is purely based on specifications. A detailed comparisons of all the features and their real world relevance will be provided in our upcoming review.
Our partners at B&H and Adorama informed us earlier today that they are already accepting pre-orders for the newly announced Nikon D750, Nikkor 20mm f/1.8G ED lens and the SB-500 Speedlight. All three should start shipping at the end of September, which is in roughly two weeks. If you would like to pre-order and support our efforts, please use the below links.
Below you will find image samples from the new Nikkor 20mm f/1.8G lens that we wrote about earlier today. Except for one image, most images were taken with the new Nikon D750. Unfortunately, since EXIF information is missing on these images, it is hard to say what aperture was used at each shot. On images with visible background blur, we can assume that f/1.8 aperture was used. Looking at the detail level, the sharpness of the lens seems to be amazing wide open. Once I obtain information about each image, I will update this article with more details.
If you would like to see what the Nikon D750 is capable of in terms of image quality at different ISO levels, check out some of the image samples below. These were gathered from different Nikon websites and unfortunately, not all of them have full EXIF information. The ones that do will show underneath each picture.
The last announcement from Nikon today was for the new SB-500 speedlight, Nikon’s first speedlight with a built-in LED light. With a guide number of 24m at ISO 100, it is not a very powerful flash unit (the SB-600 is at 30m and the high-end SB-910 is at 34m), but it is quite flexible with the head tilting up to 90° and rotating horizontally 180° to the left and right. In addition, it can be used as a commander or a remote flash unit and it is fully compatible with the Nikon CLS system. At $249.95, it is priced $80 cheaper than the higher-end SB-700. What’s exciting about this unit is not its typical features, but the built-in LED light. With approximately 100 lumens of brightness, the LED light can be used as a small video light or potentially even assist in acquiring focus in low-light situations. The LED light can be operated independently from flash, which means that you could actually detach the SB-500 from the camera and use its LED light exclusively, if needed. I personally welcome this innovation in speedlights and I believe it will be quite useful in some situations.
Together with the D750, Nikon has also announced a brand new full-frame lens, the Nikkor 20mm f/1.8G ED. This lens announcement is really exciting, because it is Nikon’s first 20mm f/1.8 ultra wide-angle lens with impressive specifications and optical design. Not only does the lens feature aspherical elements and Nano coating for reduced aberrations, ghosting and flare, but it also comes with two ED (Extra Dispersion) glass elements that are typically used in expensive, professional lenses for extra clarity and superior sharpness. With a gold ring and a price tag of $799, this lens seems to be of superb value for low-light wide-angle photography. Looking at its wide-open sharpness (more on that below), it seems like the lens could be a great candidate for astrophotography. Let’s take a look at the lens in more detail.
Today Nikon introduced yet another full-frame DSLR, the Nikon D750. Featuring the same 51-point autofocus system as the D810 and the D4S, 24.3 MP sensor, 6.5 FPS of continuous shooting speed, built-in Wi-Fi, advanced movie recording options and a tilting screen, the camera packs quite a bit for its $2,299 MSRP price tag. Placed above the Nikon D610 and below the D810, the D750 has an interesting mix of features from both. On one hand, it has a slightly faster frame rate than the D810, a slightly tweaked focus system and pretty much all the movie recording features of the D810. On the other hand, with the exception of the tilting screen, its ergonomics and body build closely resemble the lower-end D610. So what is this camera and why the D750 name? Is it finally the Nikon D700 successor that many of us have been waiting for? Let’s take a closer look at the camera and talk about what has changed.
Every once in a while, an article we post here at PL creates huge debates due to disagreements between readers and the poster, or between readers themselves on a photography-related subject. Sometimes such discussions lead to very productive results, with all parties learning something from each other. Other times, all we see is provocative and sometimes even insulting comments. One such article that contained a little bit of both was Tom Stirr’s recent post on post-processing difficult images. Before hitting the “Publish” button (and yes, I do personally publish every single article here at PL for different reasons), I already knew that it would spark up some discussions.
A decentered lens contains one or more optical lens elements that are either moved or tilted from the principal axis of the lens. Such shifting or tilting of lens elements can potentially lead to blurring / softness of parts of the image due to divergence of light rays. While very slight decentering of optical elements can be observed in many lenses, especially on superzooms, severe decentering and tilting can render the whole image blurry, with the lens unable to achieve good sharpness across the frame.
Have you ever been in a situation where light conditions were so poor that your camera would completely refuse to autofocus, with the lens constantly going back and forth “hunting” for focus? I am sure you have, since it is a very common problem. Sometimes you want to photograph your loved one in candle light, or snap a shot of your child blowing out candles on a birthday cake. Or perhaps, you are dealing with a DJ that decides to turn off all lights on the wedding dance floor, killing your chances of getting any shots in focus, even when you are fully prepared with flashes to light up your subjects. That’s exactly what happened to me and Lola last weekend when we were shooting a wedding. Lola came up to me and asked if there was anything she could do to make autofocus work again and I thought of an old trick that really does work when dealing with such situations.
