<h2>A Wildlife Photographers View of the Nikon D4</h2>
<p>Finally after 5 solid years Nikon has announced a successor to the D3. From a wildlife photographer&#8217;s perspective the the D4 looks impressive, and most importantly it looks like Nikon seems to have made an extensive series of small improvements and not a lot of big changes for still photographers. In other words it looks like they did not make any huge mistakes as Canon has done over the last few years with their pro cameras. Thankfully Nikon has aimed for it&#8217;s professional user-base and tried to improve the D3S which was probably one of the best, if not the best DSLR ever made.</p>
<h3>Upgrades</h3>
<p>Note: I have not had a chance to use the camera yet so all of this info is based on Nikon supplied info. If you would like to find out more of see Nikon&#8217;s brochure see the bottom of this post for links.</p>
<p>Some of the more important  D4 photo shooting specs are a new higher-resolution 16.2MP full-frame CMOS sensor and the ability to shoot at 10 frames per second with AF. Most importantly the continuous shooting ability has been increased from 43 shots with the D3S to 97 NEF on a CF card and 105 NEF files with the new XQD card. Limited RAW file continuous shooting capability has always been a problem for action photographers since the first DSLR.</p>
<p>Nikon reports that the  new Advanced Multi-CAM 3500FX AF system in the D4 has improved low light ability. A new 1005 pixel AE metering sensor has been replaced a new design with 91,000 pixels. The 3D tracking performance of this new color matrix metering has reportedly been dramatically improved. This is huge since I feel that the current Nikon AF system is the best AF system I have ever used. It is comforting  to see that Nikon has confirmed autofocus at f8 so super-telephoto NIKKOR users can use 1.7X and 2.0X teleconverters. Nikon has always had this capability on pro and pro-sumer cameras but new cameras like the Canon EOS-1DX  have dropped this capability. This is a very important issue for a lot of people including me.</p>
<p>The D4 a lot of new interesting capabilities with the new WT-5 Wireless Transmitter. This will allow the user to log into your camera with a laptop, tablet or smartphone and will have access to a camera control panel and live view feed with a standard web browser.</p>
<h3>The Real Challenge</h3>
<p>Image quality is really most important and I think it is the D4&#8217;s biggest challenge. I feel that the Nikon D3S is the closest thing to the perfect camera on the market right now. Nikon promises that the D4 will offer even better image quality and even better low light performance. The D3S low light high ISO performance was almost unbelievable. For an example of what kind of file the D3S can produce, look at the image below.</p>
<p><a rel="gallery[Portfolio]" href="http://www.robertotoole.com/wp-content/uploads/2012/01/Dalmation_Pelican_ISO_25K_900px.jpg"><img src="http://www.robertotoole.com/wp-content/uploads/2012/01/Dalmation_Pelican_ISO_25K_900px.jpg" alt="Example" width="600" /></a></p>

</address>
<p>This is the kind of image quality the D4 has to beat. The image made at an astounding 25,600 ISO is almost completely noise free. For the record no noise reduction or blurring has been applied, yes the D3S is that good!</p>
<p>I would be surprised if the D4 will be able to surpass the IQ of the D3S at high ISO but if it can at least match it the D4 will be worth the 3 year wait.</p>
<p><em> </em></p>
<h3>Things Missing From the D4</h3>
<p>Enough resolution to make the D4 the first true dual mode camera. Rumors have been circulation for years that the D4 would offer high full frame resolution and a 12-14 MP 1.5x crop mode with a higher frame rate. This would be the ultimate camera for action and outdoor photographers. Full frame and a faster 1.5x mode when you need extra speed and reach. The D4 offers more resolution but it looks like it will only provide about 6-7 MP in crop mode. Maybe next time? D800 maybe?</p>
<p>No removable viewfinder, I still miss this feature from the film SLR pro camera era.</p>
<p>No built in incident meter.</p>
<p>No removable upgradable sensor.</p>
<p>No removable low pass filter.</p>
<p>No built in RAID SSD hard drive with thunderbolt connector for downloading.</p>
<h3>What I Do Not Like About the D4</h3>
<p>Nikon made a mistake dropping the AF-Mode selector on the back of the camera and replacing it with the the same AF mode / AF manual mode combination switch from the D7000. All of the online reviews I have read claim that this change is an improvement, for me its a bad move for photographers. Nikon went from a brilliant AF-Mode switch that only took a single finger to operate without even looking.  The D4 / D7000 design uses an outer collar that rotates to select auto or manual focus, and selects the AF mode when the center of the selector is pressed while the command dial is rotated. Honestly almost all D7000 owners I have met dont even know how to use the combo switch. I don&#8217;t even have my D4 ordered yet but I already miss old style AF-Mode switch.</p>
<p>At least they didn&#8217;t touch the AF-On button!</p>

			<content:encoded><![CDATA[<p>Thinking about buying a macro lens for the first time or thinking about upgrading soon? Instead of comparing a big load of specs and lens photos lets look at some real world images to help you decide on a lens. To see what effect focal length would have on the subject and the background I made this series of images with 3 different lenses, 180, 150 and 50mm. To keep the subject size constant the camera and tripod was moved closer for each lens change. F/7.1 was used to make all of these images.</p>
<p><a rel="gallery[Portfolio]" href="http://www.robertotoole.com/wp-content/uploads/2011/12/180mm-new-1.jpg"><img src="http://www.robertotoole.com/wp-content/uploads/2011/12/180mm-new-1.jpg" alt="Example" height="600" /></a></p>
<address>Orchid at 180mm, National Orchid Garden, Singapore. NIKON D700 and Sigma 180mm f/3.5 EX DG IF HSM APO lens,  1/125 sec at F7.1, manual metering on zero, ISO 640. Image Copyright  2011 Robert OToole Photography. </address>
<p>This image was made with a 180mm macro lens, my personal favorite. The sharpness and bokeh,  aesthetic quality of the out-of-focus areas, are extremely good. The long working distance (distance to the subject) allows you to stay farther away from the subject with the 180. This makes lighting easy and helps keep you safer if you are photographing something that can bite or sting. Making this orchid image was easy and I was able to photograph from about 4 feet away!</p>
<p>The 180&#8217;s small angle of view makes it easier to keep the background clean and free of unwanted objects compared to a shorter focal length lens. In terms of sharpness I find the 180 sharp at all apertures and works very well with 1.4x, 1.7x (Nikon only), and 2x teleconvertors/extenders. 180mm is a popular focal length and available from almost all the major manufacturers (Nikon makes a great 200mm f/4 macro).</p>
<p>How does the 180mm compare to a 150mm lens?</p>
<p><a rel="gallery[Portfolio]" href="http://www.robertotoole.com/wp-content/uploads/2011/12/150mm-new-1.jpg"><img src="http://www.robertotoole.com/wp-content/uploads/2011/12/150mm-new-1.jpg" alt="Example" height="600" /></a></p>
<address>Orchid at 150mm, National Orchid Garden, Singapore. NIKON D700 and 150mm F2.8 EX APO DG HSM Macro,  1/100 sec at F7.1, manual metering on zero, ISO 640. Image Copyright  2011 Robert OToole Photography.<br />
</address>
<p>The 150mm is extremely sharp, light, compact and works great with teleconverters.  This is the lens I usually reach for when I am packing for a trip. Using this lens in the field was a pleasure, the working distance for this image was a respectable 3 feet. Sigma is the only manufacturer that makes this focal length but I would not hesitate to recommend this lens to any camera owner regardless of brand. This is not the stabilized version of the 150 macro and unfortunately I have not had a chance to use the new OS version of this lens. I have heard good things about the Sigma 150 OS and I look forward to getting to try one in the future.</p>
<p><a rel="gallery[Portfolio]" href="http://www.robertotoole.com/wp-content/uploads/2011/12/50mm-new-1.jpg"><img src="http://www.robertotoole.com/wp-content/uploads/2011/12/50mm-new-1.jpg" alt="Example" height="600" /></a></p>

<p>The 50mm macro is a good all around lens and is reasonably priced when compared to other macro lenses. The biggest strength of this lens is the size and weight but the focal length is just too short if you are photographing small subjects especially small moving subjects. This lens was my least favorite to use since it was so difficult to use in the field. The camera was only about 1 foot away from the orchid  when I made this image so it was hard not to block light and to position the tripod.</p>

<p>When I made these comparison images I did not exactly know what to  expect and I was shocked to such a big disparity in background quality between the 180 and 150 images.What do you think?</p>
<p>The 150 image above looks sharp and the background looks good but compared to the 180 image there is no contest. For a nature / wildlife photographer I would rate the 180 by far the best in  terms of image quality and ease of use in the field. Even though I own all three of these  (and a 105 macro) I always choose the 180 when I go out to do macro  photography and the 150mm when I travel. Most modern macro lenses on the market today are comparable but make sure you choose a lens with an ultrasonic motor, called USM, HSM, or AF-S. This gives you a huge advantage when photography anything in motion, this is very important even in macro photography.</p>
<p>I hope this information images helps you decide on a macro lens or maybe even make you think about upgrading to a longer macro lens in the future.</p>
<address>Notes:<br />
</address>
<address>I did not include a 80 or 105mm macro in this comparison but based on experience  I would put this range in between the 50 and 150 but nowhere close to the 180.</address>
<address> </address>
<address>Don&#8217;t forget that when you change camera sensor types, full frame to DX for example, the effective focal length will change but the lens angle of view will not.<br />
</address>
<address> </address>
<address>If you plan to use teleconvertors or extenders  with your macro lens make sure you check with the manufacturer. Some lenses like the Sigma macro lenses used in this comparison only work with the manufacturers own lenses. A Nikon teleconvertor will not work on the these Sigma lenses, but the new Sigma 150mm OS lens does work with the new Canon extenders.</p>
</address>
<address> </address>
<address>Unfortunately one lens I used to make this comparison, the Sigma 180mm is discontinued. I hope Sigma replaces it with a 180mm  OS macro in the future.</p>
</address>
<address> </address>
<address>Another factor to consider when deciding on a focal length is that modern internal focusing auto focus lenses will actually shrink as they focus closer even if the physical length remains the same. This is due to IF lens design, they shift lens elements or element groups within the lens as they focus closer. So a 200mm lens is not a 200mm lens at a close focus distance. Nikon actually published this data for the old 200mm F/4 micro-Nikkor macro lens, this lens would shrink to 140mm at 1:2. The new  Nikon AF-S VR 70-200mm 2.8G ED II shrinks to 160mm at 1:18.<br />
