And while some sharpening haloes are visible, they're not as pronounced as those from the A7 II, D810 or 645Z. Contrast falls a little as sensitivity rises, but the ISO 6400 crop is surprisingly close to that at base sensitivity. When it comes to high-contrast detail, the Sony A7R II turns in a very good performance. Sony A7R, Sony A7 II, Canon 5DS R, Nikon D810, Pentax 645Zĭetail comparison. (That's in part due to the different scale of the two images making that from the Pentax appear softer, but it seems the Sony camera is also using a bit stronger sharpening.) The same is also noticeable in the mosaic label, although not to the same degree. Where the Sony A7R II has lost most of the thread pattern in the fabric swatches, its medium-format competitor still retains quite a bit of that detail. Once again, the huge sensor of the Pentax 645Z yields a better result at ISO 3200. And remember, you can always go to our world-renowned Comparometer to compare the Sony A7R II to any camera we've ever tested! For those interested in working with the RAW files involved: click these links to visit each camera's respective sample image thumbnail page: Sony A7R II, Sony A7R, Sony A7 II, Canon 5DS R, Nikon D810 and Pentax 645Z - links to the RAW files appear beneath those for the JPEG images, wherever we have them. Clicking any crop will take you to a carrier page where you can click once again to access the full resolution image as delivered straight from the camera. All cameras in this comparison were shot with our very sharp reference lenses.
NOTE: These images are from best quality JPEGs straight out of the camera, at default settings including noise reduction and using the camera's actual base ISO (not extended ISO settings). And for good measure, we've also included Ricoh's superb Pentax 645Z DSLR, giving a comparison with a current-generation medium-format camera. Since resolution is the name of the game here, we've also compared it against the highest-resolution DSLRs from rivals Canon and Nikon, namely the Canon 5DS R and Nikon D810. Below are crops from our laboratory Still Life target comparing the Sony A7R II's image quality to its predecessor, the A7R, as well as its more affordable sibling, the A7 II.
