Video auto focus not working on Nikon 3100


Recommended Posts

Elliot B.

It's in Auto mode, but it doesn't work in M mode either.

It works in photo mode, just not when recording videos.

The lens is on A and VR is set to ON.

Any ideas?

From a quick google search.

If you have changed the Autofocus area from AF-A to AF-S or C that could be the problem.

Can you manually override focus ( eg. try focusing with your hands? this so we can discard the lens is malfunctioning)

Pressing the AF button does nothing. Half-pressing the shutter focuses but I can't keep doing that.

Press the <i> button and navigate to the <m> in the column on the right and change it to <af-s> or <af-c> or <af-a>

Press the <i> button and navigate to the <m> in the column on the right and change it to <af-s> or <af-c> or <af-a>

When I press "i", I get: AF-S, AF-M or MF.

It's currently set to AF-S.

EDIT: AF-F works. Cheers for the assistance :)

      Huawei again caught passing DSLR photos as being shot from its own smartphones
      by Rajesh Pandey



      Back in 2018, Huawei was caught passing off some photos taken from its mid-range Nova 3 when they were actually shot using a DSLR. The company had been caught using similar unethical tactics before as well with its P30 series. Fast forward to a couple of years later and Huawei has again been caught doing the same thing.

      Huawei recently ran a photography contest on China's Weibo platform and shared some of the photos submitted to it with the "taken with Huawei smartphones" tagline in a video. However, it was soon discovered that some of the photos select from the competition were taken with DLSRs. The issue was first discovered by Jamie-hua after he thought the photos shared in the video from Huawei looked familiar and eventually he found one of the photos on 500x which was taken from a $3,000 Nikon D850 DSLR and not a Huawei smartphone.

      The image in question/ Credit: Su Tie After being called out, Huawei issued an apology saying it was an "oversight" by the editor who "wrongly marked" the photos. The company has since then already updated the original video to remove mention of the photos being taken from a Huawei smartphone. The company claimed that the competition rules did not prohibit users from posting photos taken from other non-Huawei devices.

      Huawei smartphones are known to have impressive cameras, so it's unclear why this phenomenon of passing DSLR photos as ones being shot from its phones keep occurring.

      Image credit: Edgar Varjapetyanvia (Wallpapers Wide) In an attempt to keep its customers "inspired, engaged and growing," Nikon USA has made its entire curriculum of online photography classes free of cost this month (via The Verge). Until the end of April, all 10 classes, which cost between $15 and $50 each, can be streamed for free. The company wrote on its website:

      The ten classes, which are taught by professional photographers and often Nikon ambassadors, range in length from 15 minutes to over an hour. Several of these classes cover Nikon-related products while others teach the basic know-how of photography. Even if you are not a Nikon camera owner, you still might learn something from these classes.

      If you're interested in streaming for the courses, you should visit Nikon's official website. After signing up using your name and email address, you will be able to view the classes. There is also an option to opt-out of receiving marketing emails.

      Nikon has opened the doors to entries for the company's annual photo contest, and is offering a top prize of 1m Yen (approx. $9200/?5600/?7100) in equipment with 500,000 Yen cash for the overall top prize. Running since 1969 the competition this year will feature 7 categories including a new 'Home' theme and a 'Generation N' section for 10 entrants aged 19 and under. With themes that include work in video as well as stills, Nikon has for the first time opened the competition to digital images captured on any digital imaging device ? including smartphones, camcorders and medium or large format cameras.
       
      Scanners are once again not classed as 'digital devices', so images captured on film will not be eligible for entry, despite that Nikon F6 and FM10 film cameras are listed as current products on the company website. 
      The panel of 17 judges will be led by Stephen Mayes, the Executive Director of the Tim Hetherington Trust and Secretary to the World Press Photo competition, who will head the photography categories. John C Jay, who was voted among the top ten most influential Art Directors of the Past 50 Years by the readers of Graphic Design USA, will head the judging panel for the video categories.
       
      Open to professional and amateur photographers around the globe, the competition attracted 99,339 entries from 153 countries last year. You have until 15th December 2014 to enter.

      i just found a Nikon D3200 with 18-55mm + 55 - 200mm telephoto zoom lens for ?379.
       
      it's on sale for only a few more days, and was wondering, if it's worth buying, i'm going to be travelling in a few months and probably taking a lot of pictures and video, but don't really have the money for the camera just yet. 
       
      is it worth it? should i find the money and get it? or wait / find a different camera?
