This is part II of my post from last week on my first impressions on the new Nikon 300mm f/4 AF-S E PF VR. Let me start by saying that the weather here in Switzerland has been fabulous this November. We’ve been treated to constant 15 degree C temperatures for the past 3 weeks. OK, not so good from a global warming perspective, but that’s another issue. So for several days in a row last week was I was lucky enough to have very similar lighting conditions on Lake Neuchâtel, just a few minutes on foot from where I work. On 3 different days I took either my D810 or D4 with 3 AF-S teleconverters and shot for about an hour each day (at the end of the day) with various combinations and the new 300mm VR. I mostly trying to evaluate autofocus speed and tracking ability, as well as overall image quality. In total, I shot about 600 hand-held frames and I’ve posted about 50 of them below. For the most part I was quite pleased with the results. The “handholdability” (a word?) of this lens is quite incredible. About these shots:
- I mostly tried to shoot with the aperture wide open, even with teleconverters, to estimate image quality at maximum aperture.
- I’ve processed these images from raw NEF format as I normally would – very little contrast, saturation and sharpening were added, for example.
- Some cropping is applied for some photos, but nothing deep or extreme, unless otherwise noted.
- Pertinent EXIF is at the bottom of each image. Look at the last number “35mm focal equivalent” to determine if a teleconverter was used. For example; 420mm = TCE-14E II; 500mm = TC-17E II; 600mm = TC-20E III. Some oddball focal lengths indicate that I’ve shot the D810 in 1.2 crop mode (ie. 504mm = 300mm x 1.2 x 1.4 TC).
- Click on each image to zoom to a 2000 pixel image. If anyone wants to see full resolution samples I can also post a few.
- Photos are posted in 2 groups, by camera body (D4 & D810). Both camera bodies drove the AF in the 300 similarly. I tend not to use Group Mode in the D810, rather single, 9, 21 or 51-point AF. Both bodies officially support AF up to f/8 with teleconverters (with the restriction of using only 11 AF sensors on both D4 & D810).
On both the D4 and D810 the AF tracking on this lens is excellent without the teleconverters, and very good up to and including the TC-17e II. It’s not as fast to lock on a moving subject as the 300 f/2.8 VR, mind you, but not as far behind as I would have expected (the 300 f/2.8 VR II is arguably Nikon’s best lens for autofocus performance). Basically it’s how we would except a modern Nikon AF-S lens to handle. Granted, I can’t quantify this observation, but I try to judge the AF performance by target acquisition time and ease (no “hunting”), as well as ease of tracking – especially with backgrounds that are “busy” – that provide less contrast with the main subject (i.e. see birds flying against shoreline, below). At f/8 with the TC-20e III, there is a noticeable drop-off in AF acquisition speed, especially in low-light situations. However, if the contrast is good between the subject and the background, both bodies were quite competent at maintaining AF lock. As expected, image quality degrades slightly as we add longer converters, but even at f/8 with the TC-20E III, the image quality if very good, and certainly usable. Acuity at distance was better than I expected as well (see pics below of distant mountains). Swinging this small lens around at 400mm, 500mm and 600mm focal lengths while tracking birds in flight does require high shutter speeds. Best results at 1/1000s or higher. Of course, higher ISO will likely be necessary to maintain these speeds and this will also affect image quality. For most of these shots, I used auto-ISO up to 6400 with a minimal shutter speed of 1/1000s. I usually turn VR off on shutter speeds of 1/500 or faster, but I was curious to see if the “sport mode” VR on the 300mm E PF could simply be left ON at higher shutter speeds. Indeed, I don’t see any evidence that leaving VR ON, using “sport” mode, had any negative effects on image quality. D4
D810 Not too shabby either. I had less-willing subjects as far as action / birds in flight are concerned. However, for this series I was physically closer to some of the birds (sparrows) and you can see that imagine quality is excellent. For some of them I’m cropped slightly deeper, but as we approach 1600 ISO, the noise starts to become more apparent (relative to the D4), especially when cropping – not a fault of the the 300mm E PF by any means, but a simply a characteristic of the sensor used in the 36 megapixel D810.
