Got APS and (Micro) Four Thirds?

I'm interested to hear your views about the relative merits. our otherwise, of the two sensor sizes, especially the latest mft sensors.

Ian

Got APS and (Micro) Four Thirds?

I think the differences are only meaningful in the context of the other interdependent elements of the camera. For example a good quality lens makes a huge difference to image quality.

In optimal circumstances the a larger sensor should out perform a smaller sensor, in a real world situation is too close to call and you would be hard pressed to tell the two apart judging the final output.

I have the fuji xpro1 and the OMD and my subjective bias is the expro 1 is marginally better because I have bought into the idea that bigger is better, and I also need to justify the cost of the xpro1 to myself and to my wife.

However the reality is they both produce terrific images and when objectively considering the output the truth is they are different rather than better and worse. I think for me it is more useful to start with the general characteristics of the camera and how these lend themselves more favourably to certain usage.

Re: Got APS and (Micro) Four Thirds?

I have both my OMD system for versatility of coverage and I also have a Fuji X100 that I love for landscape and general work when I want to stick to 1 lens - I also love the tactile handling of the Fuji over the Oly.

On the quality side, I would say there is not a great deal of difference between the two and for street & general documentary work they produce parallel results (providing I use a good prime on the Oly).

For landscape work I do prefer the X100, the results it gives me are superb with a great dynamic range and that lens is really good, some of the best landscapes (moody) I have taken of this type have come from that camera.

I am hoping that I can save for the 12mm and start to do more landscape with the OMD but in the meantime, I will continue to balance the 2.

Here is a link to the landscapes taken in Derbyshire when I was there on work.

Re: Got APS and (Micro) Four Thirds?

Whenever I use both I'm slightly irritated by the 3:2 ratio, but I'm sure that's irrelevant to this thread.
I don't think there's a difference in terms of noise now, the small differences across brans and internal processing seems to make more difference than the basic sensor at the root of the camera.
Bear in mind my thinking is really referring to the e-M5's sensor as THE m4/3rds sensor, not any of the other 16mpx Panasonics : which is wrong, sure but then we could just include Samsung's APS-Cs or the Foveons ...
I'm talking about Sony's base sensors : the extra width of APS-C makes not a ha'peth of difference to IQ compared to every other factor going into the mix.
Bit rambling?

Re: Got APS and (Micro) Four Thirds?

My view is that sensor size determines the size of the lenses and hence the weight that you carry around. I would think the future is smaller sensors, just look at what ipads and mobile phones can produce. I would not buy a camera on sensor size its the functionality that concerns sells to me. There cannot be much to choose between the relative performance of these given the small difference in sizes. At the end of the day it is the lenses that will determine the quality of your picture.

I hope you are not teasing us Ian an E7 or omd-* with a APS sensor!

Re: Got APS and (Micro) Four Thirds?

I kind of understand what you are saying, but if I could put a larger sensor (APS C) in my E M5, I would have the best of both worlds. I don't know enough to be technical but I do notice a difference between my photos and a friend at my camera club who shoots FF. Following a day out when we both heavily cropped macro photos, hers were definitely better than mine. So yes, keep the technology, size, weight and quality of M4/3 but a larger sensor would be a bonus.

I really, really love my E M5 but when I go on my safari holiday next year i am seriously considering taking (or even upgrading) my Nikon which I have hardly used since buying the E M5......I'm ducking right now!

Re: Got APS and (Micro) Four Thirds?

It seems to me that there is little to choose in IQ between the best of current APSC and u43 sensors. Where the diffence lies is in the lenses - both in terms of of size and what's available.

If we look at APSC DSLRs, we find in general the bodies are bigger than u43 but, more importantly, so are the lenses. Partly this is because of the mirror box but partly it's because the range of APSC-specific lenses is limited, forcing users to go for FF-compatible lenses which are much bigger. Aside from AF performance considerations, I don't see APSC DSLRs offering much in the way of advantages over u43 - the IQ won't be any better and the size of the gear will be bigger and heavier.

APSC mirrorless designs fare better in the size department than DSLRs, but so far the lens range offered is poor compared to u43. Sony's Nex system has a poor selection of lenses from any perspective - IQ, build, size and FL ranges among them. Fuji's X system has some nice lenses, but the range is still narrower than u43 and the lenses are still bigger/heavier.

Re: Got APS and (Micro) Four Thirds?

I found the problem with both APS and FF was finding lenses of the quality of the HG and SHG 4/3 ones.

Of course, at the moment my 4/3 zooms are gathering dust as I've rediscovered the joys of manual focus primes.

Re: Got APS and (Micro) Four Thirds?

Hi Anne, you are a stirrer! When you go on your safari have you thought of matching a micro 75 (or 100) - 300 lens to your E-M5? That is equal to 600mm lens for your ff friend and imagine the size & weight to carry that around, let alone the need of a tripod to stabilise it! Not really a safari tool.

Not if it opens up greater possibilities like multi-aspect (like GH2) & the ability to adapt & use other lenses. OK, I'll go back to sleep & stop with the dreams.

Re: Got APS and (Micro) Four Thirds?

Having just recently seen Damian McGillicuddy at work and looked through the brochure in the Oly goodie bag given away at the Giffords Circus event I can't see any reason to worry about sensor size. The latest 4/3 sensor will do me fine.

Re: Got APS and (Micro) Four Thirds?

I have both an EM5 and a Canon 7D. I use the EM5 for all my normal photography, including static birds, and the Canon for birds in flight. A strict comparison isn't easy as I don't use them with the same lens but I have used the EF400mm f5.6L on the Canon and the M.Zuiko 75-300mm on the EM5 for the same subject on occasions. These have EFLs of 640 and 600mm so close enough for a rough comparison. My opinion is tha the EM5 definitely has the edge for sharpness and noise characteristics, although with LR5 the Canon noise seems slightly easier to deal with. The Canon 400mm f5.6 is acknowledged as a cracking prime lens and when I use it, with adapter, on the EM5 the results are outstanding and even when allowing for the extra reach it definitely beats the Canon for IQ. Now I have got back into MF I use this combination more often and frequently with a 1.4x Kenko converter.
I don't regard these results as a measure of the difference in sensor size but as commendation for the Sony sensor in the EM5 compared to the Canon, so if Olympus or Panasonic want to produce a camera with APS sensor that does PDAF as well as Canikon then my 7D is gone - won't part with the EF 400mm though!

Re: Got APS and (Micro) Four Thirds?

Not enough difference in image quality but a big weight and size difference that I am selling my APS kit for a OMD to go with my Pen.
