Review Sony RX1R camera – VnReview


Sony's RX1, which has been considered a perfect product by many, but Sony has done the impossible: power up RX1, remove LPF filters (low-pass filters) and improve performance. ability to process JPEG images.

The result is that JPEG images are greatly improved. However, the R1XR is more prone to streaking (moire) and jagged than its twin. These comments are drawn from the experience and evaluation process of the site ImagingResource, the detailed content is translated by VnReview below.

When launched, RX1 has won many prestigious awards, and with the special version RX1R, Sony also raised one level. If you are a RX1 fan, you will probably agree with the view that the combination of Carl Zeiss 35mm f / 2 lens and full-frame sensor on RX1 is no match.

However, by eliminating the LPF anti-aliasing filter (low-pass filter) to increase the sharpness of each pixel and improve the JPEG processing capability to suit this change, Sony brought a version RX1R has much better image quality. The red "R" on the RX1R body shows the new focus of this camera: Resolution.

Difference between RX1 and RX1R

Overall, the experience of using RX1R compared to RX1 is not different. If you've ever used RX1, you'll figure out exactly how to use the RX1R. Users enjoy the flexibility of the interface as well as the diverse features of RX1. The RX1R works and looks exactly like RX1. The most noticeable difference when using RX1R is JPEG image quality.

Photos taken with the RX1 are vibrant and sharp.

Design

When held in hand, the RX1R is a very solid camera with very good hardware quality. Like on RX1, the ability to "fit" a 35mm full-frame sensor into a camera classified as "compact" like the RX1R is a great achievement. Both RX1 and RX1R are unique cameras thanks to this design option. Both Sony models produce very good image quality, have a very light body and much lower price than Leica M. Although it is hard to fit the RX1 or RX1R into the pants pocket, the jacket pocket will be too Enough to accommodate this full-frame compact camera from Sony.

Lens

Carl Zeiss f / 2 lens is equipped for the RX1R with very good quality. Thanks to the large sensor and aperture of f / 2, the RX1R delivers surprisingly high quality shots in low-light or backlit shooting conditions, and it can also create a very DOF (depth of field). good.

Just like on the RX1, the semi-automatic aperture rotation on the RX1R helps to bring a "nostalgic" feel. The reason for calling a "semi-automatic" rotation is because of modes such as Program Auto or Shutter Priority (RX shutter priority), RX1R will still control the aperture automatically, and the rotation will not change the aperture. RX1R level.

Performance

The RX1R's focusing speed is very impressive. In good light conditions, or when shooting high-contrast models, the RX1R can successfully focus in seconds, even when focusing on objects that are too far or too close. When focusing and focusing again on the same objects at the same distance, the RX1R successfully focuses almost instantly. However, if focusing on low-contrast objects, the RX1R is a bit slow and may encounter hunting (continuous focus but cannot focus).

Experience using

Due to its small size, but very solid, and also capable of capturing high-quality images, the RX1R is a great camera for those who like to take street photos and take photos while traveling. Landscape shooting. If you can "tolerate" RX1R's fixture lens and accept "zoom with … feet", the RX1R can become a very good alternative for DSLRs for everyday photography. .

The RX1 is fast and its small body is great for street photography. This is a product for photographers who want to bring with them a good camera anytime, anywhere.

Disadvantages: Many stripes

While RX1R allows you to create super-sharp JPEG images, the machine suffers from a major error: stripes. As expected, RX1R produces significantly more stripes and more jagged than RX1. Users of RX1R should pay attention when shooting objects such as felts, grilles, metal surfaces or window screens.

The stripe effect is much more recognizable in RAW format. RX1R has the ability to remove stripes for very good JPEG images, almost entirely in most cases. The table below compares stripes of RX1R and RX1, as well as shows differences in RAW image format with JPEG.

Excellent JPEGs

In 2012, RX1 has been Imaging Resource Vote as Camera of the Year. Of course, the successor of this camera will receive a lot of attention.

In the lab shooting and in real life, the JPEG quality of RX1 and RX1R is very different. RX1R gives sharp and clear images in much more detail.

When the RX1 filter is removed, the definition is significantly improved than other cameras. In the remaining cases, the change is somewhat fuzzy.

The comparison below shows that RX1R is more suitable for landscape drivers than RX1, especially if they prefer to use JPEG format. In fact, Sony believes that landscape photographers will be the RX1R's largest customer.

The sharpness and clarity of the images are due to the JPEG processing process, and also due to the noise reduction algorithm that affected the RX1R image. This is how many digital cameras are restricted by low quality lenses. With a low amount of detail in the area of ​​low contrast, the anti-jamming algorithm often assumes that the remaining tones are also noisy, and thus further obscure the remaining details.

It is unclear how RX1's lens limits the performance of the machine, but the effect due to LPF filter can also work the same way. With a clear amount of detail obtained from the sensor, the RX1R image processing technology considers that what the camera really is is the object and therefore does not interfere with noise reduction.

A sharper camera is obviously better, but in reality the difference is not much. The sharper the machine, the more depth of field effect will be reduced regardless of the aperture. This means that with 3D objects near the machine and at a reasonable aperture, only a small part of the object will get enough focus, taking full advantage of the resolution.

RAW photos

Although the RX1R is stronger than JPEG, with RAW format, the distance between two generations becomes smaller. Unless you look at each pixel, it's hard to spot any improvement in the RX1R's detail and sharpness. After using Photoshop to increase the sharpness, the RX1R is slightly better than RX1, but still not as clear as JPEG.

Conclusion of image quality

Compared to the original RX1, Sony RX1R is designed to improve sharpness and detail by eliminating the LPF low-pass filter. And indeed RX1R did that when shooting JPEGs. However, the change is only very small for RAW images. Without editing, the RX1R's RAW image only offers a negligible amount of detail. Even with the help of Photoshop, RX1R still does not prove to be strong compared to RX1, except when extremely scrutiny.

Print quality

– Images at ISO 50/100/200 for 36 x 48 inch prints have amazing quality, extremely sharp and full color, enough for 48 x 72 inch print sizes.

– Photos at ISO 400 for very fine prints at 30 x 40 inches. Good detail, can print up to 40 x 60 size.

– ISO 800 for detailed, detailed 24 x 36 inch battery, almost no noise and the print is only slightly soft in red areas. The size of 36 x 48 inches is also good.

– ISO 1600 print is very good at 20 x 30 size, only slightly noise in flat areas due to anti-noise processing. At size 30 x 40, the quality is at an acceptable level.

– ISO 3200 can print 16 x 20 inches of good quality, only slightly noise and soft in red but not much.

– 11 x 14 prints at ISO 6400 images only show noise in some areas. At 8 x 10 size, the photo prints are excellent.

– ISO 12800 can print 5 x 7 images very well, even with the size of 8 x 10 and still retain the color accuracy in some cases.

– ISO 25600 is enough to print 5 x 7 images, a size rarely achieved with such high ISO.

Conclude

Like his brother, the Sony RX1R is an excellent full-frame pocket camera with a fixed Carl Zeiss 35mm f / 2 lens, for image quality on par with other full-frame DSLRs.

Should you buy RX1 or RX1R? It must be said beforehand that you will not regret any machine in this duo. Both are extremely impressive and cost equally, at $ 2,800 (about VND 60 million) in the US market. But if you need to capture the highest resolution possible and image quality is the most important factor (especially if you are mainly shooting in JPEG format) and accept some stripes, RX1R will definitely be Better option for you. If you are afraid of the possible streak effect, RX1 is a safer choice.

For current RX1 users, the RX1R's sharpness can be achieved through a firmware update, which is still a plus for Sony. However, whether or not such an update comes to RX1 users still depends on Sony.

Strength:

JPEG photos are sharper and more detailed than RX1
