<p> Here's the before.</p><div></div>

<p>Trying downloading for free from Nikon their "Capture NX-D" editing software. It has a very effective "Distortion Control" option. You're using a modern Nikon camera (D7100) and Nikon lens (40mm f2.8G DX AF-S, I'm assuming) which will be recognized by the program and will with a simple click of the mouse apply the correct amount of distortion correction. You can also "Straighten" and "Crop" with the program, altho the crop option probably won't suit your needs. This only will work with Nikon cameras and lenses. I use it on every image I edit with that program.<br /> I'm attaching two images of a before and after edit using Nikon, Capture NX-D.</p>

<p> Erik. <br> True again in what you're saying. All I was trying to give was a simple answer for something for Avishek to try. <br> As for as the AF-S 80-400, that could very well be miss handling. But I had the usage of the older AF-D 80-400 version with the screw drive about 12 or 13 years ago and it did that to me with the VR in Active Mode. And also about the same time period I got to use a AF-S 200-400 for a week with similar results. Each lens did it only a couple of times. This was with two F5's, three F100's, and one D1(the two F5's and one of the F100's were mine). Also the lenses had an odd habit of some of the images being a little soft on one side of the image. And again with multiple cameras. That's when I had contacted Nikon Tech Support about those issues and was told that with the VR system, the lens or lenses group located in VR assembly can be all the way to one it's axis limits when the shutter is released causing the VR,s lenses to be misaligned with the rest of the lens behind the VR assembly. Nature of the best. I don't follow Canon but I can speculate that there IS lenses could have the same malady seeing that Canon uses something similar. Interestingly with the Sony system I've read that there IS/VR is built into the camera body. </p>

<p>Erik Arnold.<br /> Yes you're correct about Phase Detection, but I felt that it was irrelevant to bring up seeing that it does the same with two different cameras. I was told by a Nikon tech rep, that contrast is part of the AF equation when I had contacted Nikon years back with my problem. So I can only go on what I'm told by the people that represent the product. So when I had applied that AF focus technique, it worked from that point on just fine.<br /> Also. There was a situations that I had experienced at a Best Buy with the new 80-400 AF-S VR, were if the VR is set to active, it would sometimes interfere with AF because the VR group of lens moving around in the lens. Might have been a bad lens, or me. I'm not the human bipod I used to be. <br /> I was just suggesting to Avishek to try everything possible first before spending money just to find out that there might be a simple solution.</p>

<p>The AF system in all cameras including Nikon works on contrast detection. I have used a friend's AF-S 80-200 f2.8 D ED lens (non VR) many times and have had a simular problem. What I found was that the lens focuses so fast and if the camera's AF sensor has a low contrast object it will just hunt and hunt for something to lock onto. If you aim the AF sensor at an edge of something or something with detail, the AF has something to lock onto. And with that lens if I attach a 2x teleconverter which brings the aperture to f5.6, it slows the AF down to the point where it will lock onto something of low contrast. This did it with two Nikon F5's a Nikon F100 and a Nikon D1X. I dosn't do it with my Nikon D2Xs which has the next generation AF system. <br /> Your D3 and D300 are supposed to have an even more sensitive AF system, so if that doesn't work you might have a problem with the lens not communicating with cameras properly. You can also try cleaning the lens contact pins. I use a product called Power Pen. It's a non corrosive fluid that prohibits oxidation between electrical contact and has a dry lubricating property to it. I also use it on the camera's contacts. It's sold at retailer of batteries like Batteries +Bulbs.</p>

<p> I like to thank those who responded to this posting, especially two of the more noted contributors. <br> I'd like think that after over 2000 years of civilization that the human race would get it together, but it's still far short of that. Beside this kind of problems doesn't even compare to rest of humanity's problems.<br> To quote; Earth is the Universe's insane asylum.<br> Pete Resetz</p>

<p> Righty o Joe. The safest place in a vehicle, is the trunk. That's if your vehicle has one.<br> I feel strongly about this because I've have had four cameras stolen from me over the years. Three when I was in the U.S.Army. Two from a locked wall locker, and one by the MP's. The fourth one about ten years ago,a Nikon F100, while staying at motel by the shifty motel owner, when I was emergency hospitalized because of an adverse reaction to a medication. All my other equipment was in the trunk of my car safe guarded there. Then about six months later I was at a used camera show and seen me stolen F100.(I have all my equipments serial numbers on my cell phone.) I called the local police, who came to the show and sequestered the camera until the police I had reported it to initially was able to verify the theft report. I got my camera back and through the camera store who bought it was able to give the sellers ID. I than filed charges against the motel owner, who was then sentenced to six months in jail and when he was released, I sued him for $1000.00(US) and won. Also the camera store's owner sued the motel owner to get his money back. <br> Sometimes one gets lucky and justis.</p>

<p> Rodeo Joe, I have to agree with you on leaving such items out in the open, but in her case it was a Jeep, (I'm assuming a Wrangler)so unless one has something cover with, it's out in the open for all to see. Also, some business will not let people in their facilities with any type of cameras other todays cell phones. So bring it with you is not always an option.<br> Shun, I also agree with on the safeguarding of one's image storage. I personally do carry my file CF cards on my person and once home, I as soon as possible download my image files to my computer, then to a solid state device and also burn them on to archival CD's so to have two different storage mediums because I have no idea as what next type storage will be in the future and to hopefully be able to retrieve from one of them if and need be.<br> I know that there will always be thieving miscreants, but the bases of this posting was to inform people that you sometimes can't count on the police to do the job that their obligated to do, and for purchasers of second hand goods to be viewed with caution to those of us who like to lead an honest life.<br> As a side note. The reason I posted this on the Nikon forum, was I wasn't sure what forum to post this on. I also have an affection for Nikon.</p>

<p>I looked at Tamron's website and they don't list the 17-50 mm f2.8 lens any more. but I have a copy of Tamron's 2015 brochure which shows two versions of the lens you considering (B005 and A16), but it doesn't make any kind of distinction. So I went to www.slrgear.com who evaulates varyous OEM and aftrmarket lenses, and they have a test of both vrsions. Near as I can tell, the V16 version has a focus motor within the lens that works with Nikon cameras that require that.<br /> Also. Try contacting Tamron at there website; www.tamron-usa.com to cofirm this about the Nikon mount vrsion.<br /> Apparently Rodeo Joe typs faster than me, so my response is redundant.</p>

<p> This is a warning !<br> I was prusing the Nikon page on Craigslist,Detroit (Michigan) two days ago when I saw a posting about stolen SD cards. It was from a female who was in Detroit with her brother at a club. When they left the club and returned to their individual vehicles, they found that their vehicles each had a smashed out window and items stolen. Her's was two Nikon cameras with attached lens, an extra lens, tripod, photo accessories, and the camera's backpack. His was a Iphone. They called the Detroit Police and made a report of their theft and damages, She posted on Craigslist a plea to the thief to return the SD cards that they have important images on them and a $100.00(US) reward if the thief would return them and one of the camera's do it's sentimental value.<br> When I read this it reminds me of some of the camera gear stolen from me in the past, so I respond to her via the Email Link, advising on what to do as to maybe recovering her stuff. She responded back to me the next day that she found her stuff on Ebay and as per my advice to contact the police about it. The Detroit Police said that they don't have the resources or time to investigate such "petty" crimes. I find this to be appalling. They just spent $143 Million on a stupid light rail train from downtown at a distance of just 3.3 miles ! Detroit is in a shambles with a ridiculous crime rate. The worst thing is that Ebay will not stop the sale without contact from the Detroit Police who will not take the time to contact Ebay ! With Ebay already contacted by this female as to her stolen items, and Ebay allowing the sale to go through, Ebay has made themselves an accessory to the crime. Doesn't anybody who reads this find this appalling ?<br> Last year I saw a posting on Craigslist/ Detroit for sale a brand new in the box Nikon/Nikkor AF-S 105mm f2.8G VR Macro for the unbelievable price of only $160.00(US). This lens sells for $900.00(US) new. I called the attached phone number and spoke to individual who was selling the lens to inquirie if this was indeed the price to which he responded that it was. I felt suspicious of him, so I asked questions as to what camera he was using and said a Canon ! Trying not laugh, I then asked some photography based question which made it obvious that he knew nothing about photography. So I declined to buy it as I felt that I would be purchasing stolen goods.<br> I don't really blame Craigslist or Ebay for selling stolen items if they don't that it is. But if they do such as the case with Ebay with this females cameras and equipment, this only and insult to injury. People should always purchase from such venues with caution. I mean what is the joy of using something that you could know is stolen with just by asking the right questions that you're not buying something that has caused some else so much pain and violation.<br> I can only hope that this female finds some kind of justice. I know that without my camera gear, that I feel lost unable to create art.<br> </p>

<p> Michel to expand on what you wrote and not undermine.<br> Chris, you didn't mention what brand and model of camera you're using. If it's a say a NIkon FM or a F100, both are film type, one can replace the focus screen with a brighter screen from a company called Bettie, who makes aftermarket focus screens that are significantly brighter than the OEM,s. This would help you preview the DOF through the viewfinder for you to get a brighter representation of the DOF form the aperture you chose. If your camera doesn't have that feature of replaceable focus screens, Bettie I believe can replace it for you if aclible. <br /> As far the image size in the viewfinder, not a viewfinder are equal. The image size can vary in its magnification from 1x to as low as .75x. This to accommodate all the information that surrounds the image in the viewfinder. Also the actual image coverage can vary from 100% to small as 85%. This is product of the camera's physical size. Smaller compact will usually have a less view finder image magnification and image coverage while a larger or many of the pro camera's will have a 1x magnification and 100% image coverage. Also the relief of the viewfinder is another aspect that can determine magnification.</p> <p> </p>

<p>According to the Nikon Full Product Catalog #10 (which I have), it's the HB-28.</p>

<p>Opps. I forgot to add, that any retailer who sold that brand and type of battery pack, no longer offers it for sale</p>

<p> Does anyone know what's going with Lenmar regarding the Nikon EN-EL4 batteries ? I tried calling them, but I kept getting a busy signal, this is after I emailed them five days ago with no responce from them yet. They still on there web site offer the batteries for like the Nikon D1 series cameras and other type of camera batteries. They also offer a warranty on their batteries and use either Sony, Panasonic, and or Gates cells in their packs someone told me. This is why I'm considering them aside that pack was advertised all over the Internet for $65.00 US, as compared to Nikon's going for about $100.00 US.</p>
