Sensor performance: Canon ever further behind

9 Mar

As an update to my recent post about Micro Four Thirds catching up to Canon, here’s how Sony is making them look bad with an even smaller sensor in the RX10:

Even the Sony RX10 beats the 70D across the board except for low-light performance.

Even the Sony RX10 beats the Canon 70D across the board – except for low-light performance.

Given the crop factor of the 70D (1.6) vs. the RX10 (3), the low-light performance of the 70D should be closer to 3.5 times as good (it’s a square law).

Canon have clearly placed a large bet on the success of their dual pixel autofocus technology. They’re currently still feeding on the past reputation of the brand, but how long will that meal last?


Most and least returned new cameras 2013

9 Mar

I saw an opportunity to look at what cameras had been returned at high rates, and those that hadn’t, among those bought new in 2013. Data was from a large database of users of an English language photography news website. Included are only cameras that were also released in 2013. I focus here on cameras that had been or were currently owned by at least 50 users.

According to these criteria, the least returned camera was the Canon EOS 700D (2.5% returned), closely followed by the Fujifilm X-E2 (3.4% returned). The Canon EOS 70D was returned after 5.9% of sales, and the Olympus PEN E-P5 after 6% and the Panasonic Lumix DMC-GX7 after 6.8%.

If we broaden our criteria to also include cameras that had only 25 current or previous owners, we find that the Nikon 1 AW1 and Nikon Coolpix P330 are also rarely returned (0% for both), while the Nikon Coolpix A and Pentax MX-1 also deserve special mention with 5.7% and 6.5% returned, respectively.

Two cameras that are returned in huge numbers are the Olympus Stylus 1 and Panasonic Lumix DMC-GM1 – 58% and 45% of cameras purchased were returned in these cases. Other cameras that are often returned include the Canon G16, Sony RX10, Sony A7R, Sony A7 and Nikon D5300. Remarkably, the much-lauded Fujifilm X100S was also returned by 1 out of 5 users who tried it, with the Fujifilm X-M1 doing no better either. The Fujifilm X-A1 looks set to follow a similar trajectory, with currently nearly 1 out of 3 cameras returned.

Two minor caveats apply to this work. Firstly, there is no distinction made in the data between cameras returned and cameras sold onwards through the second hand market. Secondly, the analysis disadvantages cameras released earlier in the year. For these models, some users may have sold the camera when upgrading to a newer model.

Zeiss Otus 50 better in corners, Sigma wins on price

The apparently first significant review of the Sigma Art 50mm f/1.4 suggests it’s as good as the Zeiss, but less sharp in the corners. Amazing value for the price!

List of cameras beaten by the Pentax K-3

2 Mar

Just having a little fun looking at snapsort. According to their ratings, the K-3 beats the following cameras:

Canon EOS 6D

Canon EOS 7D

Canon EOS 70D

Canon EOS 5D Mk II

Leica M Typ 240

Nikon D7100

Nikon Df – Tie!

Olympus OM-D E-M1

Olympus OM-D E-M5

Olympus PEN E-P5

Olympus PEN E-PM2

Panasonic Lumix DMC-GX7

Panasonic Lumix DMC-GH3

Panasonic Lumix DMC-G6

Samsung NX300

Samsung NX1100

Sony A3000

Fujifilm cameras cannot be compared (no score given, even for the X-A1, but DxOMark have promised to review it soon). You may notice that it also beats the GH4; however, this is based on misidentified data that gives the GH4 a low sensor score (it hasn’t actually been reviewed by DxOMark).

The only remotely comparable cameras I could find that narrowly beat it are the A7/r and the Nikon D6x0 (all by less than ten points!). Let me know in comments if there’s one you think I’ve overlooked.
