daleeight: They working with Olympus, or with OM Digital Solutions? Come on man.

OM Digital Solutions produces Olympus cameras, so both are technically correct.

I just tried it with my Olympus E-M1 and it worked really well! And I didn't have to remove the signature from Zoom to get it to work on my old iMac running High Sierra (10.13.6).

tedolf: Would this thing work with an m4/3 camera and a 30mm macro lens?


There's a thread discussing that combo and it seems to work fine: https://www.dpreview.com/forums/thread/4246359

I wonder if it would work as well using the old 35 mm macro for 4/3 mount? I have one of those and an adapter, but no native macro for m4/3.

Yohan Pamudji: f/7.1?! Remember when f/5.6 was considered slow? I do.

There was also a time when 400 ISO images were unacceptably noisy/grainy. Things change and f/7.1 on a 35 mm format isn't as limiting as it used to be. It might be a tradeoff some are willing to make for the price of image quality, price, size, and/or weight.

Rosatakon: Why do so many FF zooms go to 105mm? Is it something magic about it? Why not 100mm or 110mm etc? I would love to have something similar to my old Olympus 12-60 f2.8-4 on my RP, those extra 15 equivalent mms is really nice to have sometimes!

Traditionally it's probably because zoom lenses were often 35-105 mm, i.e. a 3x zoom.

Earlybird29: The bodies of the Olympus and Panasonic “pro” cameras are now so big together with their pro lenses that I’ve finally decided to ditch my Olympus EM1 MK II and pre-order the new Sony A7R III to get the FF advantage of much higher image quality. After spending the last 5 years with M4/3 and being constantly disappointed with the IQ even from their pro lenses I’m done with it. I also have the FF Leica Q and the different in IQ between M4/3 and FF is like night and day. My gear is going up on eBay and I won’t have any regrets. Sorry folks.

Unless you have some highly specific needs, the A7R III will probably not make a huge difference in IQ.

In reply to:

Mateus1: Tiny sensor (without PDAF in 2018) in giant and heavy body that equals FF and offers 25% IQ of it? And to pay for it $1700?

I am not mad.

I'd argue that any modern camera with a 4/3" sensor or larger has at least 90% of the IQ of the best full frame camera. But then again, how do you even quantify something like IQ with a single number?

hfjacinto: If I take a regular lens and adjust focus +20 front focus won't it do the same thing and I can save $$$$?

You can save money, but soft focus is not the same as out of focus. The images here are still in focus, they just have intentional spherical aberrations that can be controlled to give the desired effect.

Anulu: Dpreview going to be smart phone review side ? Totally irrelevant smart phone articles for photographers more and more often. Yes you can take pictures with phones but they isn't serious photographs only toys for amateurs with a IQ for amateurs

A large portion of the camera news on this site is about gear not aimed towards "pros". Maybe that's why this is called "Digital Photography Review" and not "Only Serious Digital Photography Review".

Smartphones are the compact cameras of today, and people weren't complaining about compact camera news 10 years ago.

Jesse_Just_Him: Imagine your gear needs subscription to work

You’re missing a key point of subscription services, that you are fundin future upgrades that are pushed out to you when ready and instead of having to buy the next major revision. So imagine paying a small monthly fee for your camera, but then also receiving every new feature as soon as it is ready, e.g. new sensors, new processors, better AF-modules and so on.

zeratulmrye: wow...a mirrorless camera without PDAF/DFD/DPAF in 2017

I have the original E-M1 and the CDAF is noticeably faster and more reliable than the PDAF for single shots, though the difference could be down to the different lenses (CDAF on m4/3 lenses and PDAF on classic 4/3 lenses). I can't really notice any difference in focus speed between the 17mm 1.8 on an E-M1 and a prime lens on a Nikon D500, which I also use frequently, they both snap into focus instantly as far as I can perceive and are both miles ahead of the focus speed of the Sony a5000 a friend of mine has. The only time I find PDAF critical is for fast AF tracking, in which case the E-M1 uses PDAF for all lenses and works fine in good light. So I'm not convinced that a good CDAF on a consumer body is a deal breaker.

medon78: Quite pathetic...
... in the section "12-bit vs 14-bit vs 16-bit RAW":
"... option for 16-bit RAW files, if it became available, you would be pushing over 281 trillion tones per pixel. That’s a heck of a lot of data to work with – you can only imagine how big those RAW images would get without any compression!"

Well, how much more storage space would you need for 16 bits compared to 12 bit?
Hint: 33% more (16/12).


Every extra bit doubles the range of information that can be stored, but it only adds one extra binary digit of information to each number stored. So medon78 is correct about the storage and Richard is correct about the in increase in the range of numbers that can be represented by those bits.

lacix: I'm still using it, and prefer the pocketable size over the speed and other features differences. Look like new, works perfectly with iOS 9.3. Great sound and the camera part is quite fine for the use.
Make a more advanced model with the 4S size, and I'm in for buying it! :)

On a side note, the SE is considerably lighter than the 4s, so to me it almost feels easier to carry around in a pocket.

The iPhone SE is based on the same internal hardware as the iPhone 6s, which is just one generation behind the current iPhone 7. The SE will definitely be getting iOS 11 this fall (even the 5s, which is two generations behind the SE will be getting it) and will likely get updates for a few more years after that. I would expect the iPhone SE to be updated as long as the 6s, which based on previous trends will be at least up to (and including) iOS 13. The iPhone 5 and 5c are the only phones compatible with iOS 10 that will not support iOS 11.

I have some experience of professional radio astronomy. I remember my first experience when the telescope operator was telling me that the signals that we were detecting with were about as strong as cell phone placed on the lunar surface would seem from earth. That really put things into perspective for me regarding electromagnetic (in addition to light) pollution and why the observatory was in a radio-silence zone (no wifi, cell phones, microwave ovens etc.).

If this is as bad as it gets, then there's nothing to really worry about when buying a new camera.

FLruckas: Since when is 39F freezing?

Want to buy a near?

But it's really not so near.....


Water is at its densest at 39 °F (4 °C), so in a frozen body of water the bottom will never get colder than that temperature. So if there is ice on the surface, the water underneath will generally be 39 °F/4 °C.

paulski66: I imagine the mirrorless crowd isn't too happy with this choice.

The only mirror on the Instax mini 90 is the shutter button. They should instead worry about the SX-70, which, as it's an SLR, is what the pros use.
