Has anyone used Sony M UHS-ll ss memory cards with the IV? I have a book of these cards and wasn’t sure how they would perform. I’m waiting for my A7RIV to be delivered and really don’t want to spend any additional money. How much longer will the buffer transfer take? Any information would be greatly appreciated. Thank you, Jeremy
Hi, I got my new A7RIV one week ago and here are my first impressions for still photography: 1/ Ergonomics : This new body get closer to a real professional one than its predecessors. Many comments have already been made on that, so I shall not dig in. I just can witness that the improvement is real in many aspects and it is a pleasure to use this new body. Some weaknesses such as the fuzzy menus are still there but fortunately you can customize your functions. 2/ The 61MP sensor : - Sharpness and level of details is outstanding ! The gain compared to the A7RIII is clearly visible. Having said that, compared to the A7RIII, with 45% more megapixels on the A7RIV you will get a size increase of the image (cropped at 100%) of "just" around 20%. I do often print on A2 or A1 formats papers (300 ppp) and I welcome this additional capacity. For some of you, it might be of no use and the A7RIII remains an excellent choice. A word on the pixelshift : I tried it with the 16 shots option. I was not so much impressed by this option with the A7RIII, but, with the A7RIV, it is crazy ! The picture is much bigger than the basic uncompressed raw one . At 100% crop, you can print a perfectly sharp and detailed 63 X 42 inches picture ! Of course, the use is limited to scenes where nothing moves. I shall use it, among others, when shooting in museums. Despite its extremely good performance, the A7RIV cannot be compared to a medium format camera and I do not like the Sony marketing on this. A medium format body has a bigger sensor which means (for the same pixels count) less diffraction, shallower DOF, etc..and all in all a better image quality. But there is a price for that : very expensive, bulky and heavy bodies and lenses, and a much less versatile system. - In order to get the best from this new 61 MP sensor, you need the very best lenses. I did test my own gear (made of mainly Sony GM lenses) and also some other gear of my friends. The 61 MP sensor does not forgive anything. With no surprise the GM lenses were fine. With other brands, the results are uneven : a good result for example with the Voigtlander 110mm Macro, less good results with the Zeiss Loxia series. Let's remember that with such a high megapixel sensor diffraction comes earlier when you stop down. (By the way, I think it is strange to see lens manufacturers (including Sony) still selling lenses with a 22 minimum aperture). - Noise : I found that the noise comes earlier than with the A7RIII when you increase your ISO setting (beyond 800 ISO). On my side I do not care since shooting mainly landscapes and portraits, I always try to stick to low ISOs. - In Body Image Stabilization : good surprise ! the performance is very good with this demanding 61MP sensor and you really can shoot hand held at relatively low shutter speeds. Having said that, the A7RIV seems more sensitive to shake than its predecessors (I did see that with my 100-400 GM when shooting at 400) - Autofocus and eye/face tracking: no need to say that this new A7RIV is excellent. I am very impressed. - Color rendition : For what I have seen so far the new sensor gives warmer colors than the A7RII and III 42MP one. As a matter of conclusion : If not perfect, this new A7RIV is clearly an excellent product with a lot of potential. The 61MP sensor requires to be more patient and focussed on what you do : this is a small price to pay for getting high level pictures.
I currently have a Fujifilm xpro2 but I am thinking of getting the Sony a7RIV when it comes out. I am completely baffled looking at the Sony web site re lenses. A zillion choices. I would like an all purpose lens 18-135 mm or in that range, a wide angle lens, a telephoto (I currently have a 100-400 mm zoom for my xpro2) and a macro lens. I do mostly landscape photography but may want to get in to birds. I do a lot of traveling so want to be able to carry my equipment and while price is not of a great concern, I am not going to spend 10K on a telephoto lens. Any suggestions would be appreciated. (The reason I have not yet ventured in to Sony mirrorless land is because of negative reviews I have seen re the menu system)
