On Olympus OM-D E-M5 II First Impressions Review preview (1300 comments in total)

ecube: This might just replace my Nikon D5100 walk-about everyday camera. Not that it matters, 16MP is sufficient for me, however, I am confused by the so called 40 MP. I'm lazy to read the complete write-up.

I am aware but am not bothered about my Nikon lenses and dedicated flash is not compatible with Oly. I'll give my D5100 and DX lenses to my daughter and keep my D800, FX lenses and dedicated flash.

I have always admire "the camera" of Yoshihisa Maitani, the chief architect for the OM1. Brilliant visionary.

Definitely looks like an excellent camera and the price is right. Unfortunately, Oly does not have any lens close to what I like. I'll wait, in two or three years, they might. When they do, that's when I'll get the OM-D-5, price would probably drop or perhaps an even better version for the same price.

I can't join the Project//21 either because I am 71, almost 72. I have an excuse for not joining.

Fri - Maybe my reading comprehension is not as good as yours.

1 - - "Open to 'active professionals' using film or digital cameras that have at least 16MP, the competition features 10 categories including a new street/urban section that seems angled at more positive images of city life."
- - to me, this means LIMITED TO 'photographers currently making their living or getting paid to take pictures'. There is NO age limit but Retired Pro Photographers are not eligible.

While the rule is NOT EXPLICIT to what PROFESSION, I interpret it to mean PHOTOGRAPHERS. NOT just any professionals, i.e. lawyers, athletes, engineers, ad infinitum who just casually take photos.

2 - - "A category called Project//21 is open to all photographers under the age of 21."
- - to me, the age ceiling is 20 years, regardless of photographer status (Pro v Amateur). I made a descent income as a photographer when I was 16 to 20 years of age to support myself thru college.

Much obliged to learn from you

Thanks for your concern Brownie.
On a separate post, I stated settling on just one lens, something like 10~70mm 4/3rd lens (roughly 20~140mm FF equivalent) if OLY or Leica has one. Otherwise, I'll pass on this camera.

I apologize in advance if I sound like a braggart, fortunately, money is not a problem for me.

ecube: In 1972, Yoshihisa Maitani lead a team in creating the OM-1, thus begun the trend of smaller, more compact SLR that bucked the larger and bulky SLRs popularized by the Nikon F series. I remember the classic commercial that touted the OM-1 as the Mercedes-Benz of camera.

I am highly impressed by Olympus products. have the Pearl mini cassette recorder, the Pen-F, and a point & shoot digital camera that wind-up in my brother's hand (as his retirement gift) less than a week after I bought it.

I am a very happy owner of Nikon DSLR (D800 & D5100). No but . . .
I am seriously considering an OM-D for a walk-around camera.

Looks like an endorsement of Oly.
I am aware of it's capabilities and shortcomings.
My intention is to have it solely as a walk-about camera. Will only get one lens telezoom roughly equivalent to a 20~140mm full frame, which would be a 10~70mm 4/3rd lens. Otherwise, I'll just stick with my Nikon D5100 for my walk-about camera

On Opinion: The myth of the upgrade path article (1406 comments in total)
In reply to:

nerd2: It is beyond absurd to see so many people has totally wrong idea of different format comparison. Here's one VERY EASY experiment you can do, with a single camera and a single zoom lens (or two prime lenses if you prefer)

a) Put your camera on tripod, pick some subject, and take a picture of it using the tele end of the zoom lens

b) Zoom the lens to the wider end, keep the aperture same, and take picture again

c) Now crop the second image so that the FOV exactly matches the image of (1)

d) Finally resize two images into same size and compare DOF, noise and resolution of two images.

Then you will see that the first image will be cleaner (less noisy), sharper and has shallower DOF compared to the second image, while being shot with the same aperture and same exposure.

Now you can repeat b) - d) with increasing aperture values and ISO values by 1/3 stop, then you will reach similar DOF of first picture. Then two will have similar FOV, DOF, noise level or they will be 'equivalent'

Yuvalm - You nailed it!
I learn THAT BASICS in my High School Physics 56 years ago. Have demonstrated the concept when I teach photography to HS and Adult Ed. I assume you are familiar with the term Circle of Confusion.

On Opinion: The myth of the upgrade path article (1406 comments in total)

The 24x36mm (approximately) referred to as FF can have more pixel count than the APC or DX sensor. IMHO, pixel count on Sensor is akin grain size on films. In the film days, I opted for fine grain films when my purpose is to have large prints. I also use the larger (medium) format camera for better image quality. My digital cameras allow me to select the number of active pixels and the image quality. I am only interested that it work, not on how it works.

I am not going to get into the physics of lights and sensors. For those interested, simply do a search on-line on the several technical papers on those subjects.

Bottom line to me, I am happy and contented in being able to afford having both DX and FX camera bodies and the appropriate lenses and able to produce the pictures I pleasing to me using the appropriate combination of camera body and lens.

The OP maybe the only one who can answer my question.
1. Are you assuming that the individual will get a 24x36mm (approximately) sensor, I'll refer as FF for convenience, and ditch her/his APC or DX format sensor camera?
2. The lens for the APC or DX is not fully compatible with the FF body?

In case 1 -- I am able to afford having the DX body & DX lenses and the FX body & FX lenses.

In case 2 -- I am able to use ALL my Nikkor lenses for my film camera on both the DX and FX bodies AND ALL the DX and FX lenses on both bodies. Since I do not have a Canon, I refuse to speculate on the APC body / lenses.

I submit that not all who get FF bodies do so based only on the OPs assumed criteria.

Definitely way above my need or want. I am sure REAL Astrophysicist would appreciate this. Then there are those who would pretend they understand all the technical jargons and thumb their noses down on serfs like I am.

ecube: Cloud? Why give control of your files? I have two 1-½ terabyte, USB portable drives about 10% larger than a cigarette pack. One in my computer bag, another a back-up that stay at home. No need for on-line connection to access my files.

BeaverTerror -
So you are lecturing me when you don't know anything about me.

I have been using computer (mainframe) since 1959. Built my first Tower in 1986. Have built or service several computer for friends and relatives. Had ONE hard drive failure but I was able to recover the data. The hard drive that fail was an OE on a "luggable" Compaq that was over 10 years old.

Moreover, I have AT LEAST one back-up of important file stored in a fire-proof / water-proof safe. I don't know about you except that you seem to assume that every computer user is like you. BTW, I do not have a degree nor have I taken any course in computer science.

I am from the old school. No pixel peeping, just simple tool to remove dust or small unwanted distractions from the photo.
iPhoto, Picasa, Nikon ViewNX2 more than meet my needs. Otherwise, PhotoShop 7 if I really want to pixel peep.

In reply to:

Macx: This may sound like a strange request, but could you show us the bottom of the camera? I'm not a weirdo, but one of the small niggles I have with the Mark 1 is that (unless you use the landscape grip) the tripod mount is a bit off set from the sensor-lens axis.

Mack - I was addressing your Mark 1 OFF-SET Tripod mount. I don't have Mark 1 camera, I assume the tripod mounting socket is not in-line with the lens axis as shown by the link provided by Peter. I think the proper terminology for the design is ARCA-SWISS. Naturally, your tripod must have a BALL-HEAD of Arca-Swiss design that can accommodate long plates that can slide to other side. I bought mine from e-Bay.

may I suggest "Manfrotto" or "Benro" type ballhead and quick-release plate?

Oh, Low Pass Filter. From what I know, the D810 and D750 disabled the Low Pass Filter. I'm not sure if the D610 did.
My D800 and other Nikon bodies are not affected.

The New pricing for the Canon EOS-1D C announced here in DPR a few days ago now make sense. They want to clear their inventory to make room for their new line-up.

I have a feeling REAL Pro shooting Canon will buy the EOS-1D C instead of the new 50 meg models.

I don't care one way or the other, Canon is not my preferred camera, Nikon is. But I hope Nikon concentrate of refining their D800/810 and D750 with the addition of built-in GPS rather than get into the megapixel escalation.

Which of the two brand is better is not my concern, both are excellent camera in the hands of an accomplish photographer. Just a matter of preference.
