Their line segmentation and prices really makes you think about your use cases while still offering GAS for other camera models after you get any of their cameras. I don’t think they want you to just buy one camera, unless it’s the unaffordable A1.
Right. The segmentation and trickle of new features in successive yet "inferior" models suggests that they don't want you buying one camera. I'm sure they have their marketing research gripped in one hand and a fist full of dollars in the other, but it rubs me wrong. Also, for the average hobbyist or even pro searching their camera lineups on B&H it's a total cluster. I'm looking forward to the A7rV release, to see how it handles in capable hands, to see what new stuff it introduces that will no doubt appear in a different segment soon enough.
It's rather logical - refine some things like sensor (readout speed etc.) for every 2nd generation (i.e. R2>R3, R4>R5). Also to introduce completely new features like reworked AF and IBIS on high-end but not topmost model.

Seeing the results online about the Hasselblad X2D 100C's 7 stops of in-body image stabilization has me interested in how good the a7R V might be.
I had the same thought. 7 stops in the new Hasselblad is intriguing and 8 stops in A7RV would be even more so.
Some lenses (super zooms) may particularly benefit from the new feature. E.g, Tamron 35-150 would be one for sure, especially at 150 mm.
At 35-40 mm, I can reasonably confidently use slow shutter speeds down to 1/10 s handheld. Also 1/5 s is doable, by collecting 4 - 5 shots sequentially, or in a short burst. Pushing this to near 1 s can be very useful when shooting static scenes in low light. If A7RV can really perform as rumored, I may want to try this camera as a second body.
Maybe im wrong but it has me thinking it added directional abilities that where not there with 5 axis. A example maybe they added like a up/down/45 degree each way kind of thing . I keep thinging like a star effect it was once 5 stars now it is 8 stars in 3d of course. Just a thought. Im really good at handholding myself as been doing this without any aid for decades but as we age that Steady Eddie stuff will fade on us.
I personally have a passing interest in focus stacking as ive done that with manual focus forever. Some old dogs don't want new tricks.
This sounds like it has to process in camera as a Jpeg. Question Mark on this one
Now that's an interesting feature that I've wanted for ages. Olympus had excellent superresolution you could use handheld because of movement correction. That the Sony version was so difficult to use (not really viable outside of the studio and with a tripod) was always very frustrating to me. Depending on how good it is, this is a feature request I've had since the RIV came out.
And of course, we need Roger's always insightful take away:
Based on this chart it makes sense that Sony did not increase the pixel count… MTF50 in the center is under 144lp/mm, so the choice of 130lp/mm for the sensor is in the right ballpark. Corner resolution is still terrible stopped down at high lp/mm
They have to consider that their other lenses won’t perform as well as the 135GM too.
For stills there’s pixel shift which can collect the R, G, and B information on every pixel site
There is an article specifically talking about rendering of the Sigma I series, which are DG DN, but it was I series only. I could not find it with a quick search a couple of days ago.

Those tests are for over 200mp, I don’t think 60mp is comparable here. 60mp is fine, but 80mp will also be fine. aCuria wrote:

The a7R5 from a7R4 seems like comparison to the a7R3 from a7R2 (for me, anyway). By that I mean it has improvements but not necessarily to IQ in a general sense.
I'm very happy with the a7R4 and can't see adding the a7R5 unless it has some spectacular features, especially higher DR and more detail/MP.
I would like to see an upgrade, or "fix", to be able to choose minimum shutter speed in 1/2 and 1/3 stop increments. Even with built in IS, I can see a bonus for me shooting at 1/80 or 1/90 second, compared to being stuck at 1/60 or having to jump to 1/125 in poor light situations handheld (same goes for 1/20 instead of 1/15, or 1/45 instead of 1/30 to keep adequate DOF). Canon has had this feature forever it seems, but Sony has never embraced it, at least AFAIK. Same as Sony does for ISO.
Personally, I'd rather see a "stripped-down" non-sports, event, or birding model with less features (e.g.: fixed back screen) and menu items, no video, selling for around $2500. I don't use even 1/4 of the offerings on the a7R4, maybe less. If I could have M, A, and B, I'd be fine.
Except for the poor viewfinder IQ (for MF), I'd still be using the a7R2 as my main camera. Well, I am still using the a7R2 as my second camera (and another as a back-up 3rd!).
I think a 75MP sensor would be my sweet spot in my "forever" camera body, with MacBook Pro and Adobe LR.

This is exactly what I've been thinking. I didn't go for the R3 because it seemed too similar to my pair of R2. Then when the R4 arrived, I was annoyed that the second native ISO was so low (320 instead of 640 on the R2 & R3), so I stuck with my R2's. I basically only shoot at ISO100 & 640 and I like that gap.
I'm still not sure what body will replace them. If the A1 was in my budget, dual ISO at 100 & 500 would be great, but that's not feasible right now.
Forum user's thoughts on the $500 USD price increase that is rumoured this morning? Likely to start at $4k USD
I will still probably get one, but after a while and likely when one is on Sale or I can pickup a lightly used used one. $4k USD puts me off from at it at launch even though my A7RIII is well worn and showing its age.
$4,000 is probably too rich for my blood, which means I’ll just hold off until the used market begins to form. Again, holding my hot takes until the actual announcement but I do hope there’s more to this camera than what has been leaked.
I bought a R4 earlier in the year for $2900 Aud after cashback. In Aussie dollars the R5 will be twice that. Hard to justify, when my R4 and R3 and going fine. The new features looks like it will be a great update though for those that need an upgrade now. I’ll wait till the price comes down by a lot.

Based on this chart, Sony has nothing to worry about until they get above at least 100MP. The 135mm GM isn't really far off from the handful of lenses here that do better. We're standing at the bleeding ends of optical quality.
I have already asked my local dealer to make sure I get one of the first batch to replace my A7RIV studio camera; the color science on the newer cameras is vastly better IMO and for that reason alone I want one. I'm happy it's not more than 61Mpx, we really don't need that in this format as the lenses are mostly not up to snuff anyway. Just my two cents.
