The shot with the 7D and 15-85 is Out of focus.

It was one of those double blind experiments. It will be written up in the same vein as the journal articles about expensive wine and abstract art.Alastair Norcross wrote:
Why is the EXIF for all those shots the same? It looks like you have posted the same shot four times.
The claim that the Sony 16-50 is better than the 15-85 is ridiculous. Maybe it is at the test conditions that the OP used, possiblly with a little help from focus error or other glitches. I use the 15-85 on my Canon DSLR and it is my worst lens for closeup images - but for larger distances it certainly is one of the best APS-C standard zooms. I don't know any lens with similar range that has better optical performance.R2D2 wrote:

Better have a good read there first.
Agree. The menus are diabolical, a grenade attack on the index list. It doesn't make any sense whatsoever and is a massive turn off. You need the brain of an elephant to remember where things are. The biggest turn-off so far but there are others to do with focusing and on my second day of shooting with the NEX I am beginning to love my 7D a lot more.Todd3608 wrote:

Put that 400mm lens on the Sony and it will give the same picture.Flying Fish wrote:
What others have said. The 7D, old as it is, will do better than the Sony in low light, and for fast action, such as your jet or flying birds or sports, it's no contest. In addition, if you want to isolate something with an out of focus background, like the image below, well, see what the Sony will do... As Mr. Natural says, use the right tool for the job.

That squabbling has nothing to do with NEX quality really, more semantics and one guy's unedited holiday snaps and unedited enthusiasm.R2D2 wrote:

indeed!! Also, which so far no one mentioned here, the SEL 16-50PZ is one of most heavily distorted lenses when not software corrected!! Sony performs some in-camera trickery there even with the RAWs from this lens on their newer Nex'es. But luckily on the older models - where no SW correction is being applied automatically - some truly horrible lens defects can be easily observed, and they are real yucktechnic wrote:

Repeat the test at anything near full open at 16mm, and not with a bookcase or test chart shot but with a real life scene near infinity; e.g. a landscape / cityscape with detail out into the corners. I don't have any doubt which of these lenses will perform the best.
Menus are poorly thought out, but only one level deep, and you know that you can assign multiple functions to the wheel/buttons right? WB, ISO, Drive mode, PASM, Flash type etc are all available so menu diving isn't something I do very often. But I shoot RAW and A/S/M modes, so even these and the (pretty good) JPGs aren't a big concern to me.Yorko wrote:

And the 5R was released a year ago. I had a 7D on day one, so I'm painfullly aware of its age, but I still doubt a 7DII could convince me to upgrade. Four years without upgrading my DSLR is the longest I've gone, but I didn't really establish much of a pattern going from the 10D to 30D to 7D. Would this person also be shocked that my G1 X compares very favorably with the 7D and 15-85? As good in most cases. Both cameras are amazing in my book.jpr2 wrote:

Did you just express surprise that a camera released three years after the 7D with the same sensor size and slightly fewer pixels can compete with that older technology?
Well, I don't really agree with your conclusion, but a camera released three years after the 7D certainly should be able to compare favorably in terms of image quality. The images you've shown don't indicate much to me, but the 7D has held up extremely well over the years.!! And the AF of 5R's for anything that moves is simply abysmally bad, plus no built-in VF
- poor AF is the weakest feature of all Nex'es, a top of the line N7 inclusive: which I know from pretty intensive experience = two years with N7 vs. four years with 7d

Never used AF lenses So I can't post any really. I shoot with FF shooters a lot and I hear with a bunch of swear words when AF doesn't lock on ;-) I miss, they miss and the only excuse I have if I miss, is that I didn't lock MF. I'm still learning and have a long way to go yet.riknash wrote:
Very nice photos and all manual focus. This illustrates what's possible when not using the AF of the camera. Can you show us some similar photos using the AF of the NEX? I'm interested in how that would be accomplished as that's the expectation for auto focus.
a word of explanation for the EOS users - that PDAF adapter is called LE-EA2.nzmacro wrote:
The NEX does take a PDAF adaptor for the SLT lenses which seems to be the same AF speed as the SLT's and from there you can have a better variety of long lenses and zooms, nothing like what Canon has in the lens line though. Quite a few using that adaptor now with the NEX.
umm with the wonderful bokeh of cat's too though.jpr2 wrote:

And the 500/8AF Reflex is the only catadiptric 500/8 lens ever produced offering AF (it was inherited by Sony from the Minolta stable, and they even produced their own exact clone of it for a while - both are now sadly discontinued).

I just bought myself a little Sony NEX 5R to carry around in my pocket. I was pleased with the results and then compared the shots with similar lenses from Canon mounted on my 7D. I was shocked to find that the Sony delivered better results. I compared the Canon 15-85mm to the Sony 16-50mm and the Canon 40mm to the Sigma Sony fit 30mm. Perhaps not the ideal comparison but I found the Sony performed consistently better quality wise across various aperture settings as well and as it is so much easier to carry it wherever I go I feel almost tempted to retire my 7D. Have a look at the shots and judge for yourself (reduced the Canon shots slightly in Photoshop to match the 16mp sizes of the NEX, but I don't think that had any effect on the results):
Sony NEX 5R
Sony NEX 5R, 16-50mm
Canon 7D, 15-85mm

I'm sure you are well aware that the main driver of image quality, is sensor size.
The two cameras you mention, have same size sensors, and of similar generations. Therefore for most practical purposes, the image quality will be equivalent. With perhaps even a slight advantage to the Sony as its sensor is actually a bit more recent.
So no surprise here.
The shot with the 7D and 15-85 is Out of focus.
Have you tried focusing using Live view and Live mode focusing with the 7D? This avoids any miscalibrations with the AF sensor, thus should give the sharpest focus your lens can achieve.Yorko wrote:
