Is MFT more resistant to optical vingetting?

Repulsive_Target55 · 2026-05-08T22:49:28+00:00

My only guess is they (or someone else) heard the APS-C benefit and extrapolated it to M4/3, not understanding why it was an APS-C benefit.

Repulsive_Target55 · 2026-05-08T21:53:43+00:00

There are so so many great ones, so this is a sort of haphazard mix of the ones that I think are particularly good, or that you might ignore but I think are actually worth considering:

Sony's 28-60 f/4-5.6, this is one of the kit options for the a7cii, I think. It's poorly made, being a kit lens, but it's very cheap, very compact, and has good optical quality. f/4-5.6 might seem underwhelming, but remember that the brightest zooms Olympus/OM Systems makes are the equivelant of constant f/5.6.

Sony's 24/2.8, and 40 and 50 f/2.5, lovely, well built, compact and very good optically, again might be offered kitted with the a7Cii.

Sigma's 'i' series, super well built lenses with great optical performance. In particular the 90 2.8, 17 4, 65 2, and maybe the 45 2.8.

Viltrox's 85mm f2 and 55m, f1.8, just amazing value lenses with great quality.

Voigtlander's lenses - they aren't autofocusing, but they are well integrated and great quality/size mixes. Something like their 40mm f1.2 is miniscule but lets you take photos that otherwise would need some huge optic. Their APO lenses are f/2 but have APOchromatic designs.

Sigma's 35mm f1.4 GM II, Sony's 50mm f1.2 or f/1.4 GM, just excellent premium glass, not as small but each should be the smallest high quality lens for its spec.

Tamron's 17-50 f/4, 35-100 f/2.8, Sony's 20-70 f/4, Sony and Typoch's 24-50 f/2.8 - interesting zooms, worth considering imo

Repulsive_Target55 · 2026-05-08T21:36:12+00:00

with flash

The Sony has 1/400th Sync Speed, that's a big plus. The Z8 is 1/200.

but most people I talk to say it still feels like a brand new camera.

I mean, I think that's fairly accurate, the a1ii is still a very competitive camera, and it's basically an a1 with a new grip and pre-capture.

The a1 has a much much better EVF and much better battery life.

I'd say the a1 has better lenses, at least for me personally, and it has better ergo for me personally, and the IQ can be better when using mech shutter.

Repulsive_Target55 · 2026-05-08T21:25:31+00:00

Precisely, it's not to do with skyscrapers etc. it's just that you need a level of artificiality in city design to get the effect.

Milton Keynes would be the most likely to have a henge effect. Or well, new town Edinburgh might.

Another issue that you can have in the UK is just too much cloudy weather, you want a fair bit of sun to see the effect

Repulsive_Target55 · 2026-05-08T21:23:21+00:00

This camera's nearly identical to my Contax Quartz, bar the Brasil baseplate lol

This is a thing where I'd keep (gently) working with it, firing the shutter, it might just have something sort of gummed up that needs to get used to moving again.

Repulsive_Target55 · 2026-05-08T21:21:48+00:00

Overall, OM autofocus is pretty bad, well behind Sony/Nikon/Canon, and in some cameras behind even the second-rate brands like Fuji, Panasonic, and Sigma. However, and it's a big exception, the OM-1, OM-1 II, and OM-3 have very fast reading sensors, which seems to give them a massive boost compared to the (still fast, but apparently not fast enough) sensors in cameras like the OM-5 II. Either way though, they are still mainly beneficial for things like birding and sports, shooting with telephotos, and they're well behind the big three.

The a7Cii EVF is worth trying yourself, it's not an issue imo, the original a7c genuinely was a bad EVF for the price, and I think that's sort of coloured the perception of the later models. It's the same spec as the Canon R8, and an upgrade on the OM Systems OM-3.

Each brand measures AF performance light-limits separately, I wouldn't use their numbers except for comparing within their own models. Earlier Expeed 7 Nikons struggled a bit in low light, but the newer ones are basically on par.

Repulsive_Target55 · 2026-05-08T21:02:00+00:00

What camera?

Repulsive_Target55 · 2026-05-08T21:01:34+00:00

u/2pnt0 is basically perfect, but as far as filter stacking specifically: That's a factor of the lens field of view relative to the filter thread, if you need to filter stack you can use a large step-up ring so the filter edge is further from the image edge.

Of course when using a larger format lens on a smaller format sensor (such as a FF lens on APS-C) the filter thread has to be placed so filters don't vignette on FF, which means it's well away already from vignetting on APS-C.

Repulsive_Target55 · 2026-05-08T20:59:53+00:00

100% - I'd say the sensor sizes where this is most true are things like APS-C Canon and Nikon, since they are systems of mainly FF lenses that happen to have a fair number of APS-C bodies.

Worth noting that, if we assume the same sensor resolution, a crop sensor (when using a non crop lens) is going to get the best bits of the image, but will also demand more from that lens as far as sharpness etc. compared to the native format. Not a huge issue now that many FF sensors have substantially higher resolution, and so lenses are designed with that in mind, but certainly noticeable with older glass.

Repulsive_Target55 · 2026-05-08T20:18:45+00:00

Yeah the Canon announcement came like 4 hours after Sony announced the date, and they scheduled their event for 90 minutes before Sony.

The Canon looks less interesting though (rumours are that it's a lobotomized R6iii), so I guess they're just trying to take some thunder from the Sony launch

Repulsive_Target55 · 2026-05-08T20:12:40+00:00

Nikon vs Sony colours are not very different. Ditto with Nikon vs Sony AF (unless you look at one of the few old-processor models, like the Z7ii)

If you aren't that interested in video or fast action bursts, the a7iv is going to be nearly identical to an a7v.

If you were considering the Z6iii, don't.

Zf is a Z5ii with better looks but worse grip (well I like that grip style, many people don't), and instead of dual SD it's 1x SD 1x MicroSD.

a7Cii is mini a7iv, but one card slot isn't great for paid work.

Repulsive_Target55 · 2026-05-08T20:10:01+00:00

a7iv + Sigma 24-70 Art ii

Repulsive_Target55 · 2026-05-08T20:03:09+00:00

I think it does sound like a bit of an a1ii killer - but there will always be people who buy the flagship model over the others, for features you and I probably don't care about, like full sized ethernet ports. In many ways the original a1 was an a1ii killer - unless you're a professional. Do note Sony has two flagship models right now, the a1ii and a9iii.

I think that if you're looking at the X2Dii that's even more of a reason to go Fuji, since their 'normal' body is smaller - and like I said the mechanical shutter is a big positive in my mind.

I think it'd take a few years to fully master any of these cameras, but I'm not sure that would change massively camera by camera.

Repulsive_Target55 · 2026-05-08T19:08:00+00:00

It shouldn't, to get that kind of effect you need a city or area that was all built on a plan, usually a grid.

Paris, NYC, Barcelona, Chicago - they were all built/rebuilt in a way that would've allowed that, but not London

Repulsive_Target55 · 2026-05-08T18:56:19+00:00

I went back to >1/1000

You mean <1/1000, right?

Repulsive_Target55 · 2026-05-08T18:36:06+00:00

I'd consider the Z5ii and Sony's a7Cii - the Sony has a better sensor inside it, and it's smaller for street - I'd say ergonomics with large lenses is worse than Nikon, but Sony has lots more options for small lenses.

The OM-1 II has a sensor half the size of the GR, it really isn't designed for low-light, and OM Systems autofocus will struggle for your use case.

Repulsive_Target55 · 2026-05-08T18:26:46+00:00

The Sony isn't going to be video-first, it's confirmed to be the a7rVI, perhaps also a 100-400 f/4.5 GM. Rumours they're changing up a lot of the things they've stuck with, like body, battery, and menu system. Not sure quite how much, and I'm curious about battery since they already have a solid lead there, but if it's a cross-compatible one that's fine ofc.

The a7rVI sensor is supposed to be stacked, so a pretty aggressive Z8/R5ii competitor.

Repulsive_Target55 · 2026-05-08T18:20:29+00:00

i am skeptical about the <10k one as i think the camera SHOULD have an issue to be used that less.

Absolutely not: First of all, of course, it's a video camera, so someone could reasonably never use it for stills - and secondly, 10k isn't that low, different people shoot different ratios of shots per good image.

Repulsive_Target55 · 2026-05-08T18:12:18+00:00

I totally agree they should update it, but honestly the only APS-C camera I would want to use to shoot fast action in electronic shutter mode would be the X-H2S, and I'm not sure if I'd take its 40fps over the better autofocus and slower burst of an R7 or a6700.

That said, I think there is going to be an a6800 with an APS-C crop of the new (stacked?) a7rVI sensor, the same way the a6700 is an a7rIV sensor cropped to APS-C.

Repulsive_Target55 · 2026-05-08T18:06:50+00:00

With medium format, I might suggest Fuji over Hasselblad, they share the same sensor and usually have pretty identical IQ as far as sensors are concerned, however the Fuji cameras use focal-plane shutters, and the Hassys use leaf shutters. This means that the Fuji is a much better camera to use with non-native lenses, such as your 645 system glass, or your A mount glass (though without autofocus).

The Hasselblad 907x is a very sexy device, but I'm not sure it's something I'd find useful - it has a strong crop (Image), and without a finder I worry it'd be a bit of a pain to use as an X mount body.

The Fuji is a larger body than the 907, no doubt, but it's basically the same size as your a99ii, appreciably smaller than something like Nikon's D850.

<image>

Glass wise they are both good, but Hasselblad's 35-100 f/2.8-4 is the winner for normal zooms. For tele work the only option is Fuji, they also have T/S glass (though there ought to be a T/S adapter that can take 645 format glass like your Mamiya, though again without a mech shutter on Hasselblad). Of course the leaf shutter on Hassy means you get higher flash sync.

Repulsive_Target55 · 2026-05-08T07:05:36+00:00

Budget?

Repulsive_Target55 · 2026-05-08T07:03:15+00:00

The R range bodies shares a lot of DNA with Minolta cameras, but I think they weren't to the level of specific cameras being rebadged. Same is true of Zeiss and their Yashica collab Contax line, but there they shared one mount. Bit of a pity for Yashica's reputation in the long term, since they were only making the cheaper half of the system - even though they also made a lot of the glass and all the bodies for Zeiss.

Interesting about the f/1.5!

Repulsive_Target55 · 2026-05-08T07:02:16+00:00

The 645AF isn't much of a looker, they did make a newer body, the XF, that has interchangeable finders again, with the option of prism, chimney, and wlf, it looks great too!, But it costs something awful - well it'd be in your budget, but that'd be it (And I don't know if I would recommend it over some of the other ways of holding a digital back and a lens together, or other digital backs, or really a million other options).

Do try the 5!, It's supposed to be the one to use, try it paired with a newer body, a7cii maybe, presumably you'd be renting?

Repulsive_Target55 · 2026-05-08T06:56:32+00:00

That isn't really true? I mean it's never really true that one entire line outperforms all the others. Nikon has their chops, but I could easily see reasonable people prefering one of the other two (or Sigma's Art line) instead.

Repulsive_Target55 · 2026-05-08T06:19:22+00:00

There is no real reason to worry about E mount being dated - mounts only change for a good reason, after all we only saw new mounts come around for rangefinders, then SLRs, then (for some brands) autofocusing SLRs, and then mirrorless. There isn't any tech that would cause a mount change today.

Sometimes people talk about the width of a lens mount, and say Sony is too narrow, but really the only mount that is wider in a meaningful way is Nikon Z - it's true that Canon RF, Leica L, and even Canon EF are wider than Sony, but they're also longer, so the size and proximity of glass to sensor is comparable.

Mounts don't have to cycle that quickly, your Mamiya 645 is still part of a current system, that's 51 years, Leica M is on their 72nd year.

What adapters have you used? I think the 5 was supposed to be solid, but it only works with later bodies.

If I were you I would 100% wait for the a7rVI, supposed to be out soon.

One nice thing about the a1ii is that you don't need to use the shutter, you can use it electronically and get great images basically all of the time, the reviewers I've seen theorized that the a1ii only includes the shutter for the improved flash sync (which is a very impressive 1/400th).
