From 7D (Mark I) to 80D - Is it worth it, and what will I be missing?

Hi everbody,

I could get a new 80D for 950€ (which is ridiculously expensive compared to some deals the US guys seem to get on a regular basis, but still ~100€ cheaper than regular for us EU guys and therefore quite a steal).
I have a 6,5 years old classic 7D, which I still like and which still works fine. At the same time, it has some deficits, in particular AF tracking was never as good as I had hoped, per pixel sharpness also left a bit to be desired, and high ISO is :o.
Considering that the 80D has overtaken 7D in many departments, in particular AF, video features and dynamic range, I am seriously tempted. At the same time, I am not sure if I will actually gain a lot in the IQ department... of course there are six more megapixels to be had, but when looking, e.g., at DPReview's test scene

http://www.dpreview.com/reviews/image-comparison/fullscreen?attr18=daylight&attr13_0=canon_eos80d&attr13_1=canon_eos7d&attr15_0=raw&attr15_1=raw&attr16_0=100&attr16_1=100&normalization=full&widget=340&x=-0.22805507745266781&y=-0.6170194532522065

I am not sure if I am actually getting that big an improvement here of I am not just magnifying the lens flaws even more or run into the AA filter limiting resolution.


Further, I am wondering what I might miss in the 80D compared to the 7D(I).

I think I will definitely miss the thumb stick for AF point selection... the four way controller of the 70D (which should be roughly the same as that of the 80D, right?) which I briefly played around with is not located very conveniently and feels a bit mushy. I also use "spot AF" a lot on the 7D, which isn't available on the 80D if I am not mistaken. And of course there is a noticable(?) drop in build quality from 7D to xxD series, but how much this will bother me, I am not sure.
Anything else that would spring to mind?

Any experience from other people that did the same up(?)grade?

Regards

Thom Hogan: Seven Reasons Why I Shoot With (Nikon) DSLRs

HTML:
Thom Hogan has written a great article about why he continues to shoot with Nikon DSLRs over mirrorless cameras in most situations. The same reasons could be written for shooting with a Canon system. While I had my “Sony phase” for a while, I was never happy with the results when compared to Canon DSLRs. This generally comes down to what I like to shoot, and as Thom says, that may not be the same things you like to shoot.</p>
<p>For the record, I do shoot with a Leica Q mirrorless camera, and I think it’s the best small full frame camera out there for my uses.</p>
<p>From Thom Hogan:</p>
<blockquote><p>Most of the mirrorless system issues I note above will tend to go away with time, as technology “solves” some of the problems, and digital cameras evolve even more than they have.</p>
<p>But DSLRs have been benefiting from technology moving forward, too, so it’s not as if mirrorless is trying to catch up to a stationary target. The D5/D500 proves that the target is still moving in big strides forward in some areas, and the DSLR/mirrorless problem has become like one of those algebra problems you had in grade school: “If train A leaves the station headed west at 75mph at 1pm and train B leaves the station headed west at 100mp at 3pm, when does train B pass train A?” <a href="http://www.dslrbodies.com/newsviews/seven-reasons-why-im-still.html">Read the full article</a></p></blockquote>
<p>I am like a lot of you though, I’m eager to find out what Canon has in mind for a mirrorless system, whenever they decide to get serious about it.</p>

<p>Canon has released an firmware update for the ImagePROGRAF Pro-1000 printer, this brings the firmware to version 1.1</p>
<p><strong>Firmware v1.1:</strong></p>
<blockquote><p>The maximum printable height of custom paper size will be lengthened to 25.5-inch (647.70mm) with specifying in the printer driver.</p></blockquote>
<p>This still may not be enough for some people, you can read more about this from this <a href="http://www.northlight-images.co.uk/reviews/printer/review-canon_pro-1000.html">intensive review over at Northlight</a>.</p>

Canon EOS-1D X Mark II Image Quality Comparison

HTML:
<p>Imaging Resource has posted their image quality comparison between the Canon EOS-1D X Mark II and cameras such as the original Canon EOS-1D X and Nikon’s latest flagship, the D5.</p>
<p>Canon EOS-1D X Mark II vs Canon EOS-1D X at ISO 1600</p>
<blockquote><p>The 1DX Mark II continues to resolve fine detail a little better than its predecessor here at ISO 1600. Luma noise appears to be a bit higher in the shadows from the Mark II, but chroma noise is better controlled which may be why the 1DX II doesn’t do as well with our tricky red-leaf swatch (the fabric has probably also faded slightly since the 1DX was shot). Still, overall image quality is similar. <a href="http://www.imaging-resource.com/PRODS/canon-1dx-ii/canon-1dx-iiA.HTM#image_quality">See the full comparison</a></p></blockquote>
<p>Most sites and reviewers are finding that the new EOS-1D X Mark II does have better image quality than its predecessor, but that the differences are small.</p>

Patent: Improved Detection of AF Errors

HTML:
A patent showing an improved AF accuracy concept has appeared, and <a href="http://www.northlight-images.co.uk/rumours.html">Northlight has shed some light</a> on what it’s all about.</p>
<blockquote>
<p class="p1">It’s a way of improving detection of AF errors without changing the lens focus, as in the ‘hunting’ that Contrast AF does. Uses polarising filters on a plate in front of the pixels. More a concept than practical design here.</p>

All around starter kit.

Obviously our needs change over time. Our interest in the hobby change too. So do our financial means.

Maybe this is a silly thread, but lets say somebody new comes to the forum who says he is seriously interested in the hobby. The person still has not decided which genre he'd prefer to shoot, but wants a 1 camera (body only), 2 lens, all around "starter" kit.

The OP states he's willing to spend between $2k-$5k so we all give two or three different kit recommendations at two or three different price points. One recommendation includes an APSC camera and the other FF.

What would you recommend? 3rd party lenses are okay, no open box, no grey market, no kit lens combo.

I guess the object of the game is to give the new "serious" hobbyist the short route to having a really nice starting setup. We all have our own idea of what this could be or what "serious hobbyist" means.

The reason I bring this up is that I took the long route to where I am and spent far more on any of the below combinations than I did on my 5D mark III, 24-70, and 70-200. In fact, it is almost heart breaking what I spent just to get to those three (before getting those three), which I think I could be completely happy with now. :D

1. 80D $1,199, Canon EF 24-70mm f/4L IS USM $899, Canon EF 70-200mm f/4L IS USM $1,099 = $3,197

2. 6D $1,199, Canon EF 24-70mm f/4L IS USM $899, Canon EF 70-200mm f/4L IS USM $1,099 = $3,197 (No brainer compared to 80D?)

3. 5d Mark III $2,599, Canon EF 24-70mm f/4L IS USM $899, Canon EF 70-200mm f/4L IS USM $1,099 = $4,597

For me, the 6D would trump the 80D easily in this situation, but only because i already know what genre I want to shoot.

AF of my 70-200 f/4L and 400 f/5.6L making noise

My (a couple of years old) 70-200 f/4L IS USM makes rubbing noise while autofocusing. You can clearly here the focus group moving inside the lens. Also the MF doesn't work anymore, it just slips. The AF at least feels very slow. I compared this to a similar lens of a friend and it was completely silent and the AF was fast. Does it need lubrication or something..?

Now I noticed, that also my 400 f/5.6L USM makes a similar rubbing noise while autofocusing. I swear it was completely silent before. Is it "normal" that you have to send your lenses to service due to this kind of AF issues?

EOS 80D Shutter hesitation?

Used my new 80D for the 1st time yesterday at an airshow with the 100-400 F5.6L MKII.

Using 'Zone AF' (the middle 9 AF points), on I'd guess 25% of shots, when I pressed the shutter button to achieve focus & then take the shot, the shutter appeared to hesitate for a moment before the picture was taken.

At first I thought it was just that I'd pressed the shutter button right down & the camera was focusing before releasing the shutter. When I slowly focused with a half-press of the shutter button and then pressed the shutter down fully it worked fine. Testing again at home I can't recreate the problem.

However I have a niggling doubt that this could be an issue with the shutter button - I had a similar problem once with an old EOS 40D which had this problem intermittently.

I'll admit the above sounds like there probably isn't an issue, but should I send it back for checking/replacement? Is it really likely that a new camera body would have a 'sticking' shutter button?

Extenders compared: Canon 1,4 III vs Kenko 1,4 DGX MC4 vs no extender

I just received the Canon extender 1,4 Mark 3 version and hoped to improve my focal length of my combo 5 DS R and Canon 100-400 II L f4,0-5,6 to 560 mm f8,0. I compared photos with the Canon extender to photos with the Kenko 1,4 extender versus crops without the extender? Which combination is the best? I would say: none of the extenders did the job properly.
What do you think?
Did I miss anything? Do you have a better experience with any of the converters? See sample pictures and my methodology here:

PRO-1000 firmware ups page length (not a lot)

New firmware (V1.1) takes the max custom page length to 25.5"

http://www.canon.co.uk/support/consumer_products/products/printers/inkjet/other_series/imageprograf_pro-1000.aspx?type=firmware

"Feature: (1.1): ROM: The maximum printable height of custom paper size will be lengthened to 25.5-inch (647.70mm) with specifying in the printer driver."

Still a very nice printer...

2nd flash vs transmitter

Hi

So I recently got my mits on a Yongnuo YN600EX-RT, and having invested in Eneloop Pros it's firing away brilliantly.

Next step is to get it off camera. Now it occurs to me that the cost difference between a transmitter (£57) and a second flash (£85) is small enough that I'm wondering if I even bother with a transmitter at all. The biggest advantage of the transmitter I can see is it shrinks the bag contents. If I'd never actually use the on camera gun as a flash when using multiple slaves then I'd get a transmitter.

So:

Those of you that use multiple flash guns.. how often do you shoot with on & off camera flash in the same setup?.. do you ever do this?

Heavily used 1Dx (original)?

I am based in northwest UK which has the same sort of weather and light levels as Pacific Northwest of North America (about the same latitude as mid-BC).
I have a 7D2 and although it is a good camera (still much to learn, though) I am toying with getting a 5D3 second hand to see how it copes with higher ISOs in lower light.

However (and hence this post) I have seen online a 1Dx with 700k on the clock with a shutter replacement 2 months ago, for about the same price and a 1Dx with 200k on the clock (also a relatively new shutter) for a little bit more.
Do you think it is worth a punt or would those be pushing reliability a tad too much?

One motivation for this is that we are heading to Canada to watch coastal grizzlies in September (so much like Manchester with its clouds, and rain....) and this seems a great excuse to get a superior camera for the conditions.
