The 70D satisfaction poll had me thinking this would be a more interesting poll and, since someone there suggested it, this should expand on the happy vs unhappy binary with a little more variety of options.

I had a 7D, loved the AF, viewfinder, built-in level, and overall performance of it.  However, i sometimes used this camera for landscape type shots because it was what I had with me when the scene presented itself and I was often disappointed with serious shadow banding if I tried doing much with the image in post.
I sold my 7D while it still got a good resale price and have been hoping a new 7D Mark II would arrive this summer with an improved sensor, hopefully providing cleaner low and high ISO performance.  If the AF improved over the original, that's an added bonus.  Once I got accustomed to the way it worked I was able to get adequate AF hits of birds, and even some bugs, in flight.  Sometimes even in low light.

I had a couple 60Ds.  I kept one of them because it's a nice light compact camera that makes a good walk-around or travel camera.  If I were to buy a 70D it would have to be all that, possibly even back to the body design of the 20/30/40/50D, AND have greatly improved sensor performance.  I'd not buy it if it offered; more video features, WiFi, GPS, a bucket full of firmware features but no sensor improvement.

I have not yet chosen to replace my 7D with a competitor's camera, mostly because of one lens there's no good substitute for, the EF 100-400mm L IS.  I could use a competitor's fast 70-200mm with a 2x adapter but that would likely cost me more than a new Canon body so I'm still undecided to pick a solution in this area.  There may even be perfectly viable options in the micro/four-thirds range to do this job but I'm in no hurry.

So...  Things to think about before voting, or buying.

• If a 70D shows up with a better sensor than the original 7D or 60D, and an improved AF system over the x0D line, maybe even comparable to the original 7D, it would have to be priced competitively with a used, original 7D to be worthwhile to some, depending on what their intentions are for such a camera.

• What level of sensor and AF performance improvements might you want from a 70D or a 7D Mark II to entice you to buy one?

• If the 70D doesn't have sensor performance improvements over the 18MP sensors that Canon has supplied over the past few years, will you still consider buying it if all it provides are some extra features like raw video out, WiFi or GPS?

• If the 7D Mark II gets an AF system comparable to the 5D Mark 3, maybe 10 fps, but does not get much, if any, improvement in sensor performance, will you still buy it?

• What is the minimum set of improvements, over the previous body being replaced, would you say is enough to warrant Canon releasing this as a product with a new badge on it?  Would that make you buy it?

• Are you considering cameras from competitors like Sony, Nikon, Pentax, Olympus or others?

• Have you already purchased a camera from one of the competitors because it offers better performance in some way compared to what Canon is currently offering?... or is rumored to supply?

• Or have you had enough of the rumors of future Canon products, looked at available competitor's products, and still decided that it's time you tried a full-frame camera instead? (even though they have different trade-offs compared to crop sensor cameras)

Any other viewpoints you'd like to present, share and discuss are welcome, of course.
And Canon, watch this thread. :)

Just watched the video, posted February 15th, where the high performance of this new lens is designed to not only meet the sensor abilities of cameras like the D800 for resolution, but also to provide very high sharpness and contrast, corner-to-corner, wide open.  Some of the printed test comparisons they show are VERY impressive.
Wish I could justify one of these! 
Addendum:  Expected price at launch is 3000 Euro.

throw in the stabilization and much lower price this lens is certainly worth considering if you don't have the budget for Canon's latest or the Nikon.
It also beats Canon's f/4 offering at a similar price point.

Anyone been using it?  How is it working for you.. subjectively?
Other than it's less-consistent across-the-range performance and likely less rugged build than the Canon, I don't see much for drawbacks to the Tamron for shooters who don't need best-in-class gear in this range.

Let's see how well this thread holds up!

We've got lots of threads here with various sides arguing the merits of read noise and banding in files, fixed pattern noise (FPN), dynamic range (DR), some on annoying lens aberrations and plenty more.

INSTEAD OF RE-HASHING THE TIRED OR UNFINISHED ARGUMENTS, POST YOUR IMAGES HERE THAT SHOW THE FLAW THAT RUINED THE SHOT FOR YOU.
If it's subtle, tell us what it is (and where) versus what you hoped for or expected.
Avoid posting images that started with poor technique or other major problems that are user errors rather than equipment flaws. If you were close but couldn't fix it in post...  Show before, after, and describe what you wanted to achieve.

We have a lot of good people with good advice on good equipment here.  A BIG HOLE IN THE INFORMATION, in my opinion, IS WHAT ARE THE WEAKNESSES OF A PARTICULAR CAMERA OR LENS or other bit of equipment that can make it impossible, difficult, or frustrating to get the shot you wanted.

LET'S SEE THE BAD STUFF SO WE CAN LEARN TO AVOID IT OR WORK AROUND IT and not miss any more shots because of it.  I, for one, had been a little too remiss in the past and I accepted of a lot of positive reviews on equipment only to find out shortly after buying and using it that it had some significant flaws that hindered its usefulness to me.

POST YOUR REMEDIES OR WORK-AROUNDS.  If discussing the issue, please EDIT YOUR QUOTING TO MINIMIZE THE QUOTE TO ONLY WHAT'S REALLY NEEDED instead of quoting everything including all the graphics.

Let the bashing, and learning, begin!
Have fun, keep it civil, make it EDUCATIONAL.

Addendum - to give you an example, here's a scaled shot taken with a 5D Mark II and EF 70-200mm f/2.8 L IS II
The image is basically ruined by garish, multi-outlined bokeh.  This is not a crop, this is the full frame.
200mm at f/4.0

hasty typo fixed, supposed to be 200mm, not 20mm.

Third Party Manufacturers / TAMRON'S thinking about making FAST PRIMES
« on: February 05, 2013, 11:43:56 PM »
short video clip to watch, from the guys over at Pentaxforums.
Interview with Tamron marketing guy.

www.youtube.com/watch?v=jRrELlKv0mw Small | Large


with the decent performance of their moderate range zooms, I'll be very interested in seeing them return to making some good primes to compete with OEM and Sigma in the "affordable" market.

Too bad the old Adapt-all theme is not returning any time soon.  Would be great for us multi-platform types.

If you're interested and have a chance, let them know you'd like them to produce some.  I'll likely be talking to my local rep in the next couple months about it.

here's an interesting story.
Instead of the color filters used on typical Bayer or other patterned image sensors, this is a color-splitting method based on diffraction within the sensor surface.
This could utilize significantly more incoming light to create electrons for readout signal.
Overall increase in effective QE and SNR possible.

IMO, This may be a method better suited to tiny pixels in small sensors rather than larger sensors and larger pixels in higher end cameras. Either way, an interesting and promising development.

Just saw this on some other sites tonite.
They've been making lots of wide zooms but i haven't seen a new medium long since I can't remember when.

http://photorumors.com/2013/01/28/new-tokina-at-x-70-200mm-f4-pro-fx-vcm-s-and-at-x-12-28-f4-pro-dx-lenses/

Nothing on Tokina's site yet.

Looking fwd to test results.
Canon's and Nikon's offerings are already pretty good but there's still some room for improvement.

24
for now, anyway, and likely for a long time to come
That's gotta make y'all happy if you bought one. :)

The Tamron would suffice for me for what I'd use it for and how I'd use it.

Got to play with one a bit at the shop today, shot some dark frames and pushed them as i usually do to better visualize the pesky noise patterns.

The 6D is considerably improved over the 5d2 and even 5d3.  Although the total amount of dark level noise is not so greatly reduced, the subjective annoyance of its patterning is noticeably less.

5d2 could produce some fairly harsh noise lines (hor. & vert) in shadows at 100 ISO, they soften a bit from random noise at 400 ISO and up.

6d, at the same ISO settings, produces far less obviously structured noise lines.  THIS IS A GOOD THING! :)
Canon has actually made some significant improvement in this area over the older cameras!

6d's overall noise is more random and uniform, tho still exhibits some fine vertical stripe structures at 400 ISO, similar to 7d's low iso noise but not as severe.  Overall there is still some coarse but smooth transition variations in horizontal and vertical axis, almost like large blotchiness.  This would not show up on large prints anywhere near as bad as 5d2 or 7d noise stripes.

6d's subjective total noise at 400 iso is similar to 5d2 at 100 iso.  And the 6d's noise would clean up better with NR software.

6d's high iso performance is impressive!
I could print a decent 6x9" from a reasonably exposed 25600 iso shot! (larger if not too fussy)

So, altho 6D's dynamic range will not be significantly better than 5D bodies at low ISO, its raw files should provide more post-processing leeway because of the reduced severity of patterned noise. Its extra performance at high ISO is a definite bonus.
Fussy shooters who do a lot of post-processing should definitely consider the 6D over either 5D body if low ISO performance is critical to their work.

 SoNikon sensored cameras still do blow the 6D into the weeds with far cleaner low ISO data.
Hopefully Canon's (soon to be released?) next generation sensors will further improve on this dark/read noise issue.

As it is now, I am very tempted to sell my 5D2 to fund the 6D, it's that much more usable to me.

Third Party Manufacturers / New Nikon 70-200mm f/4 VR hands-on
« on: December 12, 2012, 02:45:01 AM »
Just picked one up today, had a bit of time to play with it indoors.

First impressions are very good.  It handles well; zoom and, more importantly, focus rings operate very smoothly with slight damping and very little dead-play from one direction to another so MF is quite usable (~150 degrees end to end) and much better than on the f/2.8 version I passed on because of sticky MF feel.

AF is quiet and fast, especially when the 3m and beyond limiter switch is on.  AF accuracy in low light, using center (cross type) AF point on a D5100 body was spot on at all distances between MFD of about 1m to about 8m I had available.

The VR (optical stabilization) worked very well also, getting pixel-sharp handheld shots at 200mm and 1/15s with no problem.  I suspect it could go even slower and still maintain a reasonable keeper rate.

Still have to do stop-down focus shift tests, check the bokeh, CA and corner shading on FF but so far, so good.  I'm looking forward to putting it to more tests and then shooting some real subjects with it.  The smaller size and reduced weight are pleasant changes from hauling around the big 2.8 glass. (altho the new Tamron 2.8 is interesting and will be considered as an option for my F-mount systems)

I did not opt for the very pricey OEM tripod mount.  I'll wait until there's a better value alternative but I would deem it a necessary item if using this lens with a lightweight body like the consumer-oriented D5100 or similar.  It's just too much mass and length to hang off the end of a plastic body when using a tripod.  It might be OK when mounted on a more substantial body like the D800 or other semi-pro or pro chassis.

Since I rarely use my EF 70-200 f/2.8 L 2 wide open, this smaller, lighter, and possibly as-sharp option may supplant one more bit of my Canon kit.  The latest Canon classic fast zoom has been disappointing me with ugly bokeh too often anyway.  I didn't use the EF 70-200/4 IS so can't compare it.

So if any Nikon users are considering this lens... YES, it's certainly worth considering.

Third Party Manufacturers / D5200 review
« on: December 07, 2012, 07:54:07 PM »
great if you can read the original Chinese?..

google translation is vaguely useful too.
Looks like an interesting camera, class-leading features?..  Some perhaps.
Looking forward to tests from sources I rely on.

meanwhile, here's the link posted by NR:

Third Party Manufacturers / Nikon's new 70-200mm f/4 VR rated 5-stops
« on: October 24, 2012, 12:30:26 PM »
I've been looking forward to this lens and hope it performs well and handles better than the very sticky manual focus on their f/2.8 v2.
Also hope it doesn't have the focus-breathing issue. I want my 200mm to be 200mm at close focus.

If this thing can perform at least as well as Canon's f/4 IS then I have one more mainstream zoom in my Nik-kit.

Price for the tripod ring is nuts!  but so is Canon's.

Has anyone who's experienced shadow banding issues with their 7D tried the version 2 firmware to see if it made any improvement over version 1 firmware in this regard?

I was considering trying it but had some concerns the v2 firmware raw files might also play differently with older software I'm still using, or more correctly, might no longer play at all.

None of the other changes in v2 firmware for the 7D are of any use to me so I have no point in upgrading and possibly breaking my post-processing workflow just to test this and it's too much like work to try hack back to the earlier version.


When I had my 5D2 it seemed to have more pronounced midtone banding (e.g. blue sky) using v1 firmware.
After the v2 firmware updates the midtone banding on my particular 5D2 camera was rarely noticeable, altho shadow areas are still an issue of course.


FWIW, the only reason I keep the 7D is because its works great on my 100-400mm L zoom and gives me great reach for birding and wildlife while also providing a more reliable AF system than any other crop body I've used on that lens.

Street & City / City Skylines
« on: October 05, 2012, 03:40:25 AM »
Shot these in some nicely transforming lighting conditions before and after sunset.
The vivid sunset colors, reflected on the windows of office towers in 0622, were not even visible from my shooting location.  A string of migrating geese can be seen near the top, above the tall white building.

I hadn't actually intended to get something out of this shoot, was just testing an old 400mm prime lens that was dropped and has some fungus issues.  The lens has its flaws, but they're workable and decent results can be had with some work in post.

Got some interesting looking city skyline shots?
or other shots that turned out well even when you didn't intend to "commit photography?"

Pile them on.
