E-5 VS E-M5 mark 2 iso test

Hi everyone, I did a senseless test to compare the old E-5 and the most recent E-M5 mark 2 with regard to sensitivity:

Still today I find the photos of the old E-5 very pleasant and I often prefer them to the ones of the last releases.

Re: E-5 VS E-M5 mark 2 iso test

you can definitely see the difference when you get up to ISO 6400. I left a comment on your site in English as I don't think my Italian is good to be intelligible.

Re: E-5 VS E-M5 mark 2 iso test

Thanks to the smaller number of pixels, the E-5 managed the noise fairly well. I remember an interview in which Olympus declared that 12 mega pixels were the maximum for their sensor and that they would not exceed them. Marketing unfortunately forced it to do so. I always regret a 12 mega pixel sensor with Sony technology and Olympus processor for the new cameras, it would have been exceptional.

Your language is good, no problem. I have a TG-5 with 12 mega pixels. It's good, unless you want to crop a lot....Not really good for birding where you inevitably need to crop significantly...………..

Re: E-5 VS E-M5 mark 2 iso test

The TG-5 has a much smaller sensor than 4/3 and above all the lenses make the difference. The TG-5 is excellent for endurance and extreme outings. On a compact in my opinion the maximum limit of mega pixels would be 8 to get pixels of decent size. I remember that the E-1 had 5 mega pixels and they were great for professionals, then we lost our way.

Re: E-5 VS E-M5 mark 2 iso test

Small file sizes mean less processing and faster storage for better fps performance in burst mode.

Rather than spending a fortune on leading edge technology with a confusion of options that tries to do it all, I prefer having several cheaper cameras each for specific purpose.
They will of course continue improving sensor performance, but new designs also can have teething problems that I'm quite happy to let others discover before I buy into it.

Re: E-5 VS E-M5 mark 2 iso test

The problem with Olympus is the numbers, a few years ago it risked failing and marketing took over in business. Sales are made with the numbers written above the boxes, to present a 12 Mp reflex today, even if with a sensor equipped with all the recent innovations, flanked by a double processor, it would be suicide in terms of sales. The big regret is the optics, those of the 4/3 system were "magic" for color rendering, the new ones have less personality. I remember the interview in there Olympus stated that the E-5 was designed to get the most out of those lenses and in fact compared to the E-3 it was much better than it could get.

Re: E-5 VS E-M5 mark 2 iso test

The E-5 had the rather elderly 12MP Panasonic sensor which had really not undergone many improvements since the original Micro Four Thirds Panasonic G1.

At that time, there were complaints that the Panasonic sensors weren't as good as the old Kodak sensors.

So forgive me for being slightly cynical!

I also don't know if the OP has conducted his comparisons with RAW or JPEG files?

I think the general opinion was that the Kodak sensors had better colour reproduction, but worse noise at higher ISOs? I had an E-300 for a while which was very noisy even at just 400 ISO, although modern software does a much better job on the raw files than was achievable back then. Sadly DxO Photolab, my preferred software, doesn't support the E-300. Affinity Photo does however and I can get better results than the original ooc jpegs, especially in terms of noise. I haven't tried the latest Olympus software however, I assume it supports the E-300?

Re: E-5 VS E-M5 mark 2 iso test

It is not entirely accurate, the E-5 had a reduced anti-alias filter and asked the image processor to filter the photo, obtaining greater clarity and more light on the individual pixels. The Kodak sensor was fantastic for color rendering, I regret the E-1 for that but it had a lot of noise already at 400 ISO. My comparison is made with the jpegs of the machines with noise filter off.

Re: E-5 VS E-M5 mark 2 iso test

Yes, the E-5 was the first to introduce a reduced anti-aliasing filter but I don't believe the underlying silicon was much different to the E-30 or the E-620. The E-5 also enjoyed improved JPEG sharpening algorithms.

After experiencing the Sony "star eater" and reading how Nikon had made the same mistake I am a firm believer that algorithmic filters belong in post processing and not in the camera. Raw images should be just that IMO... the data exactly like the sensor saw it.

RAW images are, on the whole, just that - unmodified sensor data. Sony has provided some low level noise reduction options in its RAW files with some cameras but these were not well received. Nikon uses many sensors made by Sony but says they are made it its specification. Olympus does also use Sony sensors, though not exclusively, and I am not aware that any modification is made to the RAW data.

Re: E-5 VS E-M5 mark 2 iso test

The pixel mapping function clones out defective pixels from the raw file. I noticed inexplicably my Olympus seemed to take two pictures on long exposures and when I read about it I learned the second is used to clone out noisy pixels in the first.

Re: E-5 VS E-M5 mark 2 iso test

Pixel mapping is needed by the machine to detect defective pixels and turn them off. What you notice is the noise reduction on long exposures. In that case the camera takes a second closed curtain photo and uses it to map and remove the pixels that overheat from the original photo. It is a useful feature that has always been present in Olympus. I remember that with Kodak sensors the photos above 2 seconds were even red in the pints where the sensor overheated. Today the problem is less present but above all for astronomical photography eliminating "false stars" is vital.
