I too asked this same question awhile back as I had just got the same lens you have around Christmas. I have to typically fly out of an airport that uses the small commuter planes and need something that will not be “checked”. In looking I checked out Mark Smith and Steve Perry (you might check out their YouTube videos about their bags, Mark did use a bag similar to the Lowpro lens trekker, but has now switched to a Mind Shift bag) who both use the Sony 600mm to see if they had any videos on what they use. I settled on what Steve Perry uses a Guru Gear Kiboko 2.0 (30L) backpack. It is 20.47” x 12.67” x 6.7”. It will fit the Sony 600mm /f4 with the hood, 2 bodies, 70-200, 24-70, 14mm, 4 extra batteries, 2 chargers, Anker power bank and both teleconverters. Only down side is it does not have a tablet or laptop sleeve, so you will need a separate small laptop bag for that. The way the top opens just will not allow it. I have yet to fly with it as my trip is several months away. Oh one piece of advice do not fly with the camera attached to any lens. You can damage your camera and lens, plus you can pack more stuff with them separated. It is available on Amazon in 3 versions the 30L is the only one that will fit the Sony 600mm/f4. Hope this helps.

Very nice

But it will do 583 frames of compressed RAW at 10fps which the D850 with the battery grip gets 12? But then the buffer fills up after about what seems like maybe 24 ie 2 seconds then it hangs so granted not the A1 but not a dog either. I can remember shooting film and we thought 7fps was amazing. But I do agree if they want it for landscapes etc. keep it.

I have/had both cameras so knowing from experience of using the D850 for over 5 years and having switched to Sony 3 years ago with the Sony A7RIV and now with the A7RV and using it for 2 months now the biggest difference is it has an auto focus system that actually works. It is amazing on how it locks on to the Birds Eye and stays there, people, insects, etc. it is also a lot lighter to carry than the D850 with the grip is a brick and the Nikon glass you need to go with that camera. I was a diehard Nikon user bleed yellow and black I had the D100, D2x, D7000, D7100, D810, D850, Z6, Z7, Z6ii, Z7ii(still have this one) and “the Z9” along with 15 lenses all of which I have now sold. I still have all my old Nikon film cameras. So why I did I switch, was out shooting birds one day with a friend that was constantly Sony this and Sony that. I had the D850 and he had the A7rIV. I was getting a few shots in a burst in focus with the D850. Looking in the viewfinder of the D850 you put the focus box on the subject and prayed it would focus on the subject. He gave me his Sony to try and it seemed that you just had to point the camera at the subject and bang a little box came up and locked on the Birds Eye and tracked it, every shot in a burst was in focus! You did not have to move the camera to keep the focus box on the subject. You can see it actually tracking and where the focus is. After that first day he loaned me his camera to take to Conowingo dam, the ultimate eagle site in the eastern end of the country, I used it there and had more keepers on the Sony than the d850 which it seemed to struggle getting the shot. In a burst maybe 1 was in focus, I know people here will say my “technique” was not good, I needed to practice more and realize the how to properly use the camera an it’s short comings to get the shot. Why? When you can buy a camera that you point it at what you want to take a photo of it focuses on said subject. I bought the A7rIV and one Sony lens upon my return from Conowingo. And kept dreaming that Nikon would figure out the auto focus system and the “big update” would happen to make it work. I bought the Z7ii thinking oh boy with 2 processors they will get the system to work, nope. So 3 years go by waiting and dreaming they would figure it out plus waiting for Z lenses with some reach. In the mean time I am getting more and things in focus easier with the Sony than my Nikon to the point I was like ok for landscapes (ie something fixed and not moving the Nikon system works great) the colors of the Nikon seem richer I will use the Nikon for that. But something “moving” I used Sony plus they had big glass that was longer and lighter than Nikon. The A1 comes out I get that use it well over a year before Nikon finally releases the holy grail Z9 then 6 more months waiting to get one or even see it. I get one after all I have a ton of Nikon glass. It is a brick, weighs a ton compared to the Sonys. By then I had gotten used to the Sony focus system actually working and the ease of shooting with it. The Z9 compared to the D850 or any of the Z’s worked amazingly better, but it seemed to get the focus on the bird but then lock on the branch or the bird behind the one I wanted. I found I preferred using the Sony over egads the Nikon. This was devastating to me I loved Nikon I had all of the Z lenses except the stupid 50mm that weighs a ton and cost as much as a 400mm, all of the new Nikon lenses for the D850. So going back to the original question, I can say with my experience and knowledge between the two that the A7rV has a focusing system Nikon users dream of and still dream that the next update will get better. The A7rV system is even better than the A1’s. So if you are wanting to shoot any that moves or even just try Sony the A7rV is an amazing camera and you will probably never pick up a Nikon again. I know blasphemy and 40 lashes. And for the Canon users here why not go there, well I tried the Sony first plus the Sony looks and has buttons, dials etc. that are real close to the look and feel of a Nikon…remember I said I bleed yellow and black, purely an aesthetic thing I do not like the way the middle of the camera just slopes up where the prism was. I know picky.

I just received that unit yesterday and am currently trying it. But it seems to not recognize my SSD drive. (SanDisk Extreme Pro 2tb) It will only recognize a thumb drive and seems very very slow to transfer files from the camera card to the thumb drive. It took 4 minutes to transfer 7 files. I also only have some old thumb drive that I know the transfer speed is not that great on this old thumb drive so looking to see if I could find a thumb drive with fast transfer speed.

The Western Digital device is discontinued.

Thanks, this does!

I have looked at Wester Digitals web site, Best Buy and B&H. All I can find is had drives that are required to be plugged into something. Do you know model name?

The impression I get is that he thinks “real photographers” are ( oops almost used “kind of like” here the forbidden word that is a simile we must be precise) western gun slingers and have the fastest finger in the west. But I am wondering how many times did the pour girl flip her hair for him to “get the shot”. Also you can draw the conclusion or infer from his diatribe that professional “real” photographers on professional grade cameras do not need burst mode, that is for amateurs. I agree with what he is implying that to take a great photo you do not need a $6,000 dollar camera I have taken some great photos with my phone, my old Kodak box camera, Nikon D100, etc., but they are just tools we use to creatively capture the subject we are wanting to show in the photo that is the art. So not everyone needs a camera that does 20-30fps but if what you are wanting to capture a small bird in flight, the person crossing the finish line, the bird just as his feet breaks the water to catch a fish then as he flaps his wings to lift that fish out of the water, the receiver reaching for the ball and it is just barley in his fingers, you select the best tool to get that shot. Out of the 14,000 photos (which I did not know there was a limit of the number of photos one takes) that total is from several cameras I took; iPhone, Canon G7 mark iii, A1 and a7riv, oh forgot GoPro. I used the best camera (tool) to photograph what the subject or situation was. I used my phone at dinner to capture my great nephew eating, and being together with my nephew and his wife at diner shots of all of us together, Canon for hiking(yes I did have the A7riv and tripod in my pack to set up once I got there), the luau great for movies, and around the table. GoPro under water, ATV rides. A7riv landscapes (yes I wanted 60 megapixels to capture the detail of the scenery and if I wanted to make a big print) I have several enlarged on metal that are over 6’ long so I need the megapixels to do that. A1 for birds, surfers, and what drives my wife nuts waves, yes I use burst mode to start taking the photo before the wave hits so I get the point where the water after it hits the rock is at is highest, is that cheating? So as the saying goes you don’t take a knife to a gun fight you select the best tool for the situation. So what is the bulk of the shots one may ask, we were there for a month (not just on Oahu, but Kauai, and the big island) the birds, surfers, waves, sunrises, sun sets, my great nephew, photos to merge into panoramas (ie you set up a tripod taking multiple(ie more than one or two) shots rotating the camera around an axis) this is where the 6’ prints come in, landscapes etc. In looking at what has the highest number of shots, the birds, surfers and waves. Which brings us to the point of my original post I am not going to cull the photos right then or that night /day on my laptop I want to download them to get them back home so I can put them up on my calibrated monitor in my studio to then review them properly. So how can I do that to lighten my load, I know the reply will be don’t take all that crap just take one camera. Does the light bulb go off yet, that is what I want to do! I want to take two cameras, two lenses, extra batteries, chargers, and an iPad (need for entertainment on the plane, shockingly some planes do not have screens in the seat backs) it clips to the back of the seat and can be plugged in to the usb port on the seat.

And yes I am going there; the composition and technique used in the photo is not very good; the better shot and classic shot has the girl 90 degrees from the camera (ie profile, but he could be wanting to see her expression and smile which is ok making it a fun casual shot) the top of the hair is cut off in the frame it would be more dramatic to see all the ends of her hair, a more dramatic shot the subject would be further away from the background so the background can be out of the depth of field blurring it so the subject closer to the camera would pop out and be in sharper focus than the back ground (ie 3d effect like in sports photography you do not see the fans in the stands) , this would also help to separate and define the hair more since the brick is so close the the same color as her hair, the window should be cropped out or the subject stand so it is not in the field of view the window has no artistic value or dramatic effect to the composition in fact it is a distraction in that with the angle of the masonry joints angled toward the girl, which is good it draws your eye toward the subject, but once you get to the girl your eye is then drawn past the girl to the window, now if something was going on in the window that would make the windows presence add to the dramatic effect of the composition say someone looking out, in this case it is just a window and blinds. Now the window does have a shade of blue picking up the color of her shirt, which once again using depth of field (f stop thing) and the window would be in the background and blurred becoming indistinguishable and just providing the splash of color there by becoming less of a distraction. The result is a very casual snap shot of a girl flipping her hair very easy to get and can be do on a phone even, nothing difficult to capture that anyone with any camera could get. Something I have done with an old film camera that only had one mode; as fast as I could push the shutter button and advance the film that was a long long time ago. But hey that is just my opinion and you know what they say about opinions…..everyone has one. I also apologize for any misuse of words, misspellings, punctuation, etc.

Thanks to all for the constructive comments, I have ordered the file hub router and will try it out.

What I find ironic is that it is "cahale" himself is the one who first used the term "like" in his very own reply, that he is now complaining about. So I guess he is now pissed at himself for being so valley. It seems most of his posts over the past couple of years or so have been very continuous and very condisending comments. He must be a very unhappy person. Or he is trying to be funny with "fox paw" either way it is not coming off very good.

From our last cruise during New Years I found this bird in a garden on Martinique Taken with the new Sony A7RV w/ 70-200.

I am confused, what smiles are you referring to? I do not have any smiles in my post. As to the comment "set on single shot and act like a photographer" kind of hard to get these kind of shots on single shot.

I typically review what I have short at the end of the day flagging the "keepers" to be then reviewed once I get home. Photo Mechanic has been a great program to quickly review and select. It also allows you add keywords, etc.

It took about about 2 months to work through the Hawaii trip.

I shoot RAW only. It is an older iPad and only has 256GB internal storage. I typically follow the rule of having 2 backups, using my Mac Book I backup to 2 separate SanDisk 2TB drives using Photo Mechanic where it copies to both SSD's at the same time. Then when we change locations / hotels I will carry one SSD and my wife carries the other. Then when I get home it is all uploaded to my server at my house which copies the files to a NAS unit then mirrored over a NAS unit at the office, where it is then backed up to and off site cloud storage. All servers are configured as RAID 10. Those 14,000 plus photos used 1.56TB of the 2TB cards.

So the thought of only having all the photos on the cards as you might guess is kind of freaking me out. But i need to learn how to not take the kitchen sink with me every time i travel. My back cannot take it and where we want to go taking all that gear is weighing me down, pun intended.

I saw that and wondered if anyone has used it? It does not cost to much so might give it a try. Thanks!
