DPReview is Closing April 10th After Almost 25 Years of Operation

The photography business has been contracting for quite some time now, and it looks like the contraction has claimed its biggest victim yet, DPReview. It’s unfortunate to see them go, and the DPRTV guys will likely start their own channel in the not-too-distant future so I am sure it won’t be the last we hear from the crew at DPR. We wish them the best of luck in the future.

Dear readers,

After nearly 25 years of operation, DPReview will be closing in the near future. This difficult decision is part of the annual operating plan review that our parent company shared earlier this year.

The site will remain active until April 10, and the editorial team is still working on reviews and looking forward to delivering some of our best-ever content.

Everyone on our staff was a reader and fan of DPReview before working here, and we’re grateful for the communities that formed around the site.

Thank you for your support over the years, and we hope you’ll join us in the coming weeks as we celebrate this journey.

Sincerely,
Scott Everett
General Manager – DPReview.com


In anticipation of your questions:

  • What’s the timescale?
    The site will be locked, with no further updates made after April 10th 2023. The site will be available in read-only mode for a limited period afterwards.
  • What will happen to my content?You can request a download of all the photos and text you’ve uploaded to the site. This will be available until April 6th, after which we will not be able to complete the request.Click here to request your data. This link will also be available if you click on your account icon at the top of the page.

Update: That didn’t take long

BCN Video Camera Ranging – Sony Tops Sales Chart


According to BCN rankings, Sony surpassed Panasonic to become the top video camera seller. This is the first time Sony has clearly taken the lead, and it looks like the margin is pretty substantial.

  • Sales of video cameras are gradually recovering. This February, the sales amount recorded a double-digit increase of 112.1% compared to the previous year. Sales volume is still 91.4%, lower than the previous year, but the negative margin is gradually narrowing, and the same level as the previous year can be seen. One of the reasons for the early recovery in sales is the rise in unit prices.
  • Looking at the market share among manufacturers, as of February last year, Panasonic was leading by a large margin. On the other hand, Sony struggled with 18.5%. However, in August, it overtook Panasonic by a narrow margin and jumped to the top. Although Panasonic lost the lead in September and October, it was Sony that increased its market share from September onwards despite price increases. Recaptured first place in November. Since then, it has stably maintained a market share of more than 30% and is leading the way.
  • In the video camera market, the number of units sold is 41.7% compared to February 2020 due to the impact of the corona disaster, which is almost 60% less. The market environment is not necessarily favorable. However, new product categories such as action cameras and 360-degree cameras are doing well. Conventional video cameras are also regaining momentum, and we are beginning to see a gradual turnaround.
