Hi Everyone,

I'm a hobbyist photographer, a few times a month I'll go out and shoot 500 photos, often time sailing regatta photos, 1 in every 10 photos is a keeper. I just upgraded from the A7rii to the a7Riv. I currently edit my pictures on a 2015 Macbook pro with 16bg of ram and the base i7 processor 256gb ssd. If I'm working remotely and do not have access to an external hard drive I often like to sort through the photos while on the card so I don't fill up the laptop hard drive for this i will use the mac preview program or sometimes lightroom. In the past this setup was barely adequate to do editing. The wait time was a couple of seconds for loading or previewing files. This is a problem when you're going through 500 photos. Like I said, I'm a hobbyist, I'm not making money off of this and waiting to load photos that need sorting and reviewing becomes a less than fun task when you're waiting on your computer. Now that I've upgraded to the A7r iv the wait times have increased but I can also tell that the computer is past its limit, I have short hangs added into the waiting time.

 

I'm looking to build a cost effective desktop PC. I want to invest money into the parts that will mostly reduce load times and processing times.

Processor:

If I were to go Intel I'd be looking at an i7 or i9 with a LGA 2066 board or LGA1151. Will either socket have much of an impact on my load times. Also I've heard good things about AMD Ryzen these days but I don't know enough about them. 

 

RAM:

Will 64GBs be more effective over 32GB or is that unnecessary. Also What impact will RAM Speed have DDR4 - 3000 MHZ vs DDR4 - 3333 MHZ

 

Graphics Card:

Will graphics card actually have any impact on anything because its not a video game

 

Also What percent breakdown do each of these categories have on load times.

Sounds like a low rate (no offense intended), which probably justifies a quick pre-selection before the heavy lifting starts. Provided the non-keepers are easily identifiable, because they're blurry, bad moment, bad direction and the like.

A few cheap suggestions up-front:

Set the camera to record both raw and jpg. Raw for editing, if it comes to that, and jpg for quick preview. On top, you may want to set the jpg quality not to the highest setting, for even quicker preview. Since you may be previewing on the camera EVF itself, you might want to consider setting a small jpg size as well.

That should considerably cut down on the volume which does need to get transferred to a computer.

Be aware, that for the a7riv an uncompressed raw picture consumes around 120 MB of storage, resulting in 8 pics per GB. That would be more than 60 GB for the whole batch of 500 pics.

Now we're talking about data transfer rate. (We're not processing yet).

1st, from the camera to the computer:

the a7riv has a USB 3.2 type interface, which supports transfer rates of up to 20 Gbit/s, if you use a suitable cable and the computer too has a usb 3.2 interface. Else the slowest partner would determine the actual transfer rate! I believe the 2015 MacBook Pro is limited to 5 Gbit/s. In theory, that's a factor of four already! But next comes the storage card in the camera, which will likely have a significantly slower data transfer rate. You may want to read up on card readers and/ memory cards as well.

Once the data is in your computer, it must be retrieved from the disk (SSD) and loaded into RAM.

New NVMe type SSDs promise 3.500 MB/s transfer speed. So you may want to consider that when picking a motherboard.

And then there's the RAM, which has a data rate of its own. The clock speed is only one of four factors which take influence. See this. If you decide on a RAM size, be sure to split the amount among the available slots, because this will enable double- (or multi-)channel access.

The graphics card also benefits from a high bandwidth:

This s for loading and viewing.

Only the actual image processing will be done in the CPU, more or less.

I shoot moving action shots while on a moving platform(a boat). Usually it’s not a focus miss or action blur as u can keep my shutter speed very fast as I’m shooting outside. The issues with the photos are framing and capturing the moment. I’ll usually shoot 5-10 or so shots of any intended shot and pick the best moment or composition after.

 

My SD cards are Sony G tough cards I.e. the fastest possible. I’ve been shooting jpeg raw for years. It would be great to have enough computing power to drop the JPEGs and make life simpler.

My focus here is to build a cost effective computer so I don’t dread viewing and processing the photos

Batches of five hundred?  Even if you have hard/software that loads and displays the images almost immediately, I would be daunted by that. I find it hard enough when I have taken over a hundred pics of one classical concert. To the extent that I have been trying to limit myself (hey, a roll of 36 once had to last!).  I take my hat off to guys who can use burst mode and then pick one or two. Experience and  good eye, I suppose.

Anyway, all that is part of your experience but... I have recently discovered that a change of preview software makes a difference. Until a week or so ago, I was just using my OS's image viewer for that original cull. Then I found something called qimgv that makes the process of simply loading and scrolling through much faster. Operating-system dependent, but you too might find something similar. It's as good as a computer upgrade on my decade-old box.

On the other hand, if you are loading everything into a raw processor, not much will help except improving the hardware. Faster disks or SSD is a good start --- or include them in the new box.

At a typical sporting event I my end up with 1-2k photos. Typically I just upload all of them to a Mac Mini, while I clean my gear. Then preview with CaptureOne to sort through them and pick the top ones. The only delay is the process is the copying of the data from SD card to the computer, and I don’t generally just sit there and watch it.

This gives me hope. So I don’t need to build a super computer to process this stuff.

I haven't tried this myself, but you could also preview the images on a TV screen by means of the camera's built-in hdmi port. This requires a dedicated hdmi cable. I don't know if this will be any faster, but it's worth try, IMO.

Update I purchased a AMD Ryzen 9 3900x 32gb off ram and 1tb Samsung SSD EVO Problem solved. This setup cost around $1100 and benchmarks like a $13500 Mac Pro. No problem with Lightroom or previews of raws anymore. No more hangs and much faster than my old computer with A7rii photos. Moral of the story if you purchase a A7r iv be prepared to have a workstation to match. I highly recommend AMD as a cost effective solution.

When I built my computer, I was listening to a lot of music, but not doing much photography. Whatever audiophools say, audio is something that is not at all demanding of computer power, and I told myself off for having to spend some time discovering the cooler/fan combination to make the box as physically quiet as possible.  But now I do photography. And I sometimes wonder just how far behind I am in processor power and storage speed.

But my couple-of-hundred photo uploads and processing are not so slow that I worry too much about it. I'd so much rather buy a new lens than a new computer. But if I ever reach a coulpe of thousand pics per session, computer upgrade will be a priority. By then, mind you, I'll probably have all the lenses I want. I've only been at this for two or three years.

      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,

      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)

      Hi Sony Users,
      I'm new to this Forum and I've got a question concerning using the Timelapse app from Playmemories  and Premiere CC. 
      I have tons of timelapse videos that I made with my A7s, using the App but premiere doesn't accept the AVI format. Does anyone has a clue? Do I need to convert it to a specific format?
      Thanks in advance for your help.

      Hi All,
       
      I just bought an A7 MK1, and I'm pretty upset that I didn't know about the S-Log thing until it was too late. Hello guest! Please register or sign in to view the hidden content. -- That said, do you have any suggestions for achieving film-style color from my shoots? And if the only thing I can do is go 'neutral' with profile, then what should I do in post, exactly (FYI: I use Sony Vegas)?
       
      Sorry for sounding noob. I bought the A7 because of its lens interchangeability and portability. I hadn't realized it was lacking something most other modern cameras seem to have by default.
       
      Any help would be appreciated. Thank you!

    • Hi All, I realise it might be a newbie question but I am used to old analogue cameras and film or Nikon cameras rather than fancy cameras like A7III. I recently got this camera as a present in a set with Sigma Art 24mm. What I've noticed is that my photos when I'm zooming in are VERY pixelated.  Photos from a Nikon camera, with similar zoom is much smoother. Is it something typical for Sony cameras? Is it something I can change in settings? It bugs me as any skin corrections are really
    • I use my Sony Nex-6 with a variety of Nikon lens in the aperture priority mode with Release Without Lens activated and focus peaking. Recently I have tried to use the built-in flash in low light situations with dismal results. When I press the shutter button the flash does not emit a single flash and instead appears to flash three or four times in quick succession resulting in the image being grossly over-exposed. I have the flash set to the Slow Sync Mode. I  am inexperience
    • Hi there, I’m a new planespotting enthusiast with an a7iii and some budget to invest in a good lens. I cannot find a definitive answer on whether to go for the 100-400 or the 70-200 f2.8 (possibly with a teleconverter). This is for commercial jet planes at airports mainly.    Is my understanding correct that if I’m shooting around f8 to keep whole aircraft in focus the faster 70-200 doesn’t really help me, but that f8 on both these lenses will be about the same?    Thanks!
    • Hi, guys, I use an Android app which uses my phone's camera and applies some realtime effects to the footage. Unfortunately my phone camera is not good enough and there is not zoom option. Therefore I want to use my Sony a7iii camera with a 85mm lens attached to it and live stream directly to the phone. Is there a hack to achieve this? Sony Imaging edge software is capable of showing a realtime footage of what the camera sees. Unfortunately I don't know how to redirect this footage to the
