Re: Got APS and (Micro) Four Thirds?

I recently traded in all my FF kit for an OMD kit and have no regrets, the difference in IQ is hardly noticeable for my uses but the weight difference is enormous!

There are some stunning Mu43 lenses available now and I suspect many more to come and with the improvements in sensor quality in the past 2yrs and the collaboration between Oly/Sony and also Pany/Fuji, I expect that improvement to continue.

Photographers like Damian McGillicuddy clearly show through their work, the capability of the system and the potential it has for all applications and use by both amateur & professional shooters.

The niggles I have about my OMD are not great and also not relevant for 70% of my work, but they are still desires I have and would offer the same flexibility as the Big Boys - my main wishes are for:
1. AFC / tracking that works so a good PDAF sensor based system
2. Base ISO of 100 to allow max aperture shooting on bright days
3. 1/8000 or better to again allow max aperture shooting on bright days
4. Higher flash sync speed than1/320

Re: Got APS and (Micro) Four Thirds?

When the O-MD was launched in Australia, Olympus used photo fairs where people with full frame cameras could photograph a model with their own camera.She was also photographed with an OM-D. A3 prints were made on an Epson printer. The ff photographer and others were challenged to tell which came from which camera; invariably the OM-D was chosen as the ff print. The science reporters in the respected Age newspaper in Melbourne made their judgement based on the clearer, more detailed print being ff. They were wrong - they had chosen the OM-D! So as for APS...

I have heard this also happened in the UK where some pros were challenged to shoot with FF & OMD then compare the printed A3, again, most got it wrong and were very surprised.

Got APS and (Micro) Four Thirds?

Goes to show how bias works, we all see what we want/need to see, especially when we invest large sums of money and our egos into something. I bet if the photos had been clearly identified by camera type and the same people were asked to judge the for the better image the FF folk would have said the FF images and the OMD the EM5 Images ( those EM5 owners who feel secure enough to not have secret desire for a FF).

By not labelling you do get a truer evaluation. It is a fact of life is there are only truths and perceptions and both look exactly the same, ask any jury.

Aptina make the 1 inch sensors for Nikon's N and J-series mirrorless cameras - but these sensors are half the size of Four Thirds. The guy was comparing 1 inch sensors with compact cameras and smartphones

It would be inexcusable for a FF camera not to be superior in terms of fundamental sensor quality (noise and dynamic range), but real world requirements may mean that even FF may not make a critical difference (a bit like having a car that can do 200mph - when will that top speed make a difference?).

Anyway, the question was about APS-C compared to Four Thirds, so we digress

Of course you are in a perfect position to comment on the relative merits of APS and Four Thirds sensors - including the older 12MP sensor.

It was probably this part that caught my attention. " 'For Aptina this trend represents an opportunity to expand - not just with 1" sensors but right up to APS-C,' he explains: 'We've had a lot of interest. In terms of 1", we've been working closely with our current customer base and have been having interest beyond the customer currently using them - we expect to see cameras announced at the beginning of next year.' "

Re: Got APS and (Micro) Four Thirds?

Just for interest here are a couple of shots taken from a bedroom window using:

1. Canon 7D plus 400mm f5.6L

2. E-M5 plus 75-300mm @ 300.

Both at 1/400th, f7.1 on single point AF with tripod and IS off. Slightly different lighting conditions which probably affects contrast and WB. Both 1:1 from RAW files. The difference in EFL between the two lenses is only 640/600mm so not really a consideration.

1. (Canon)



2. (Olympus)



No doubt the Canon 400mm f4 may have improved the Canon results but then the ED300mm f2.8 would have improved the Olympus results. Bearing in mind the Olympus lens is a zoom and the Canon is a well established prime with very good reviews this indicates to my eye just how good the E-M5 sensor is and even more importantly the potential it has for use with an HG or SHG set of primes. So for me I think that as things stand APS does not confer any advantages, except in the AF of fast-moving subjects.

Re: Got APS and (Micro) Four Thirds?

And just think how much of an advantage the Canon 400mm has in being stopped down further from full aperture than the Olympus 75-300.

Re: Got APS and (Micro) Four Thirds?

I've just added the Panasonic Lumix G X35-100mm f/2.8 constant zoom lens to my OM-D and it blows the socks off any camera I've ever had before, including Canon EOS film (full frame) and digital (APS-C) cameras. Love it!

Re: Got APS and (Micro) Four Thirds?

I've recently purchased a Fujifilm X-E1 along with a few lenses, I'm really enjoying shooting with this camera especially since the recent firmware upgrades have put it much more inline with the current mirrorless gold standard for focussing speed (m4/3rds).
With regard to the specifics of the sensor comparison I would say that Fuji do have an edge in terms of noise handling (at higher ISO values) and general sharpness (no antialiasing filter) but the noise comparison is negated to some extent in certain situations by Oly's superb 5-axis IBIS system.
And to be honest I'm as equally impressed by the Fujinon optics as I am with the better offerings from Oly and Panasonic so I'm pretty much a happy camper with both systems, each has it's strengths and weaknesses.
