I did not make this decision lightly. I was fortunate enough in that my local camera dealer lent me a Canon 5D Mk3 and three Canon L lenses to try for a week and the results convinced me it was the right move for me. There are disadvantages, as have already been mentioned by others here, the main one being the weight factor, but after a recent trip to The Lakes, lugging around two bodies and six lenses with my old system, the difference is negligible. The advantages are, greatly improved battery life, I used to carry six previously, now only two, and image quality, which to me is a noticeable improvement. Regrets? None on my part. One last point. How many of you here edit in 16 bit, not 8. If not why not? Yes it triples you file size but you can always resize for posting etc. It seems foolish to me not to if you want the ultimate in image quality from whatever camera system you choose to use. Interested to hear other members views on this. As always, regards to all, Ian W.
I use Capture One, and when I need to go via TIFFs I do indeed use 16-bit when the target app will accept that.

Yes, you have clearly made a rational decision Ian, based on a proper test for your use case. Unfortunately so many people are seduced by what the influencers tell them, that FF is the 'ultimate upgrade'. In reality, for most people's use cases it is heavier, larger, more expensive and harder to use, and they never/rarely use the specific advantages unless they're showing off to other photographers!

I have a Sony A7S that I use only for very low-light street photography (for which it is far and away the most economic, capable option) plus for using my small collection of classic lenses at native magnification. I'm certainly not switching away from m4/3 for my other use cases, for all of which FF would be a downgrade in real life use.

In contrast to the FF mirrorless designs of Canon and Nikon (incorporating huge mounts, prioritising fast and high-quality lens designs that are huge in size as a byproduct), Nikon has recently produced a couple of really interesting light and compact tele primes, the PF 300 f4 and 500 f5.6.

They use fresnel lenses, and a friend of mine managed to get one of the 500s recently (rare as hens teeth, apparently) and I've had a brief play on his D850 big beast.

It's around the same size and weight as to 300 f4 Zuiko and gives similarly brilliantly sharp results at full aperture. However, you lose a stop of light compared to the Oly (i.e. one stop of the FF advantage is lost before you're out of the blocks) and it's 」1200 pricier and 17% shorter in equivalent focal length. He has occasionally seen some very funny bokeh in bright image detail in marginally oof areas - I suspect one's seeing a side-effect of the fresnel lens structure. An area of development that's worth watching, though.

Re: If Sensor Size Doesn't Matter, Why Buy a Bigger One?

I went to an exhibition of Olivia Parker on Fri. She specialises in still life. Her work is of the highest technical quality and it spans over five decades. She spent a time in the 80s using large format Polaroid technology including a 24"x20" beast that weighed several hundred pounds!

There was a recent video of her in her studio and I noticed that she was using Sony a7 gear.

There's something unconvincing about that peach on top of the glass box!

The PF 300 f/4 came out just after I switched to Olympus and, when the Oly 300 f/4 turned out to be much larger and heavier, I wondered if I'd done the right thing!

I wish Olympus would embrace this technology, as it would complement the MFT concept very well.

Re: If Sensor Size Doesn't Matter, Why Buy a Bigger One?

Something which has not been mentioned is comparative storage space.

Comparing RAW with RAW, my A7R AWR files are just over 36MB and the EM-1 ORF files are centred around 15MB. I am selective as to what I shoot on FF, mostly UWA.

Re: If Sensor Size Doesn't Matter, Why Buy a Bigger One?

It's mostly down to the physics of collecting photons. Just like collecting rain. You have 2 measuring tubes with the same with a scale on them, one has a 1 meter diameter funnel feeding it and the other funnel is only 6" in diameter. When you have a 2 minute shower the funnels collect the same amount of rain for their respective areas. One tube fills up nicely, the other has very little in it. You can calculate how many mm of rain fell with greater certainty for the larger funnel.

Good news for monochrome but lots of little, colour-dedicated, pixels...

Maybe we need lenses fitted with much larger diameter lens hoods, to collect more photons ?

Lens hoods are designed to cut out light so you need to take them off!

And before anyone asks, no Olympus pro cameras are not at a disadvantage because they are weather sealed.

What if we mirror coated the inside of the lens hood. I知 picturing a huge conical, blunderbuss like affair, large enough to rest on the ground and support the front of the lens thus making IS unnecessary! Plus added bonus of a built in hide, albeit a very shiny one!
I think this idea has merit, I知 off to set up a Kickstarter campaign before anyone else grabs our / my idea.

Too late Tim ! Hubble beat you to it, on their second attempt anyway

Re: If Sensor Size Doesn't Matter, Why Buy a Bigger One?

My A7 II has three tangible advantages over my more extensive M43 kit:

1. Dynamic range. I can shoot -2 stops with ease. If I use Capture One to process the raw, the penalty for this is almost unnoticeable.
2. Hand in hand with the dynamic range is native ISO-100. What I would give for an Olympus camera with true (well, as true as you can get) ISO 100!
3. The usual low light advantage, though the A7 II is considered relatively poor in this respect.

For my photo, DoF is not normally a disadvantage. If I shoot a scene at f8, on the A7 II, I can get very similar results, at equivalent focal length, by shooting f4 on my Olympus kit.

But what about size? There's not a great deal of difference between the A7II and E-M1 II. The A7 II is at it's best with a light (f1.8) prime, whereas some of Sony's fast zooms are huge. Of course, I also have a Pen F which is far smaller than either the Olympus professional body or the A7 II.

That's a completely ridiculous idea and it will never work as anyone can plainly see.
You will of course make a shed load of cash on kickstarter and reviewers with absolutely love it.
