I rented both 7D and 5DmkII before byuing one of them, so I have comparison. 7D autofocus is much more better than 5D2, so I bought 7D. After half of year I'm very satisfied, I'm using 7D in low light conditions very often (iso 3200, 1/60s f/2.2)

Please note AF is not just about camera, but also about lens, I don't know how good is 50/1.4 but I can imagine many newer lens are better, e.g. AF of 17-55/2.8 is excellent and significantly faster than my 28/1.8 and 85/1.8.

I'm using single AF, point focus and all of available AF point, with my 28 and 85 all shots are perfectly focused, ny photos are blurred only if I select to long time, sometimes I have problems with DOF, but it's my issue.

I own 7D since April, before I had 30D and before analog 33. I own 20/2.8, 28/1.8 and 85/1.8 all time.

- in analog ages I considered 85 is superb, 20 and 28 great
- in 30D ages 85 was superb, 20 still great but 28 was average/poor, esp. at low apertures

Before microadjustment all my lenses was worse on 7D than on 30D.

After MA:

- 85 is superb at f/2.2 - f/11, I can see poor quality wide open and also f/16+ due diffraction
- 28 is superb at f/2.2 - f/5.6 on near distances, wow, but still average/poor on infinity
- 20 is poor until f/4 in all distances, average at f/5.6 - f/11

7D is great, but all my lenses need MA around -8. I didn't find how to set 28/1.8 to be great on infinity, I guess it's not designed to be landspace lens, but low-light street/portret photo. I love my 28/1.8 since having 7D and MA.

I think my lenses are quite old, I tried 17-55/2.8 for two days and I was so suprised how good is the zoom both in IQ and AF accurance/speed terms.

EOS Bodies / Re: Is that really it for Canon at Photokina 2012?

My 7D is good enough to be happy with for 3-4 years, AF is nice, ergonomics, speed, noise is acceptable...

I'd like to buy

(1) 50mm prime with accurrate and fast AF
(2) some lightweight compact L-zoom for crop body with IS for video of range 17-35

What Canon offers?

- 17-35/2.8 is too expensive
- 17-40/4L is very nice, but... have no IS... a key feature for video
- 17-55/2.8 is too heavy, AF ring is too close to EF mount, not sealed
- 15-85, 17-85,18-55 are too slow

I dream about compact ef-s 17-50/4L IS, or at least about 50/1.4 IS.

20/2.8 - good for landscape, too slow for indoor, not good wide open
24/2.8 - nice lens, sharp, too long for crop, too slow for indoor, slow AF (sold)
28/1.8 - excellent for indoor at f/2.2 - 4.0, poor for landscape
50/1.8 - excellent, but tiny AF ring, poor for macro (sold)
85/1.8 - excellent at all range, my work horse, using for macro with nikon close-up 3T/4T, too long on crop bodies for indoor
100 macro - slow AF, unusable for portrait (sold)
24-70L - excellent wide open, too big for me (sold).

I dream about new 50 IS, for indoor and video.

EOS Bodies - For Stills / Re: Upgrade from 40D or upgrading lenses
« on: August 28, 2012, 02:53:49 PM »
Today I saw some great photos from my friend using 40D. I was terribly surprised how bad 40D is on iso 1600, the images has worse color saturation, contrast, resolution. My iso 1600 by 7D looks so fresh.

Lenses are important, sure. With 30D I was very happy with my 20/2.8, it was sharper than 28/1.8. Now I have 7D and feel 20/2.8 is average lens and 28/1.8 is better after settin microadjustment.

7D is not cheap, I considered to sold my 20/2.8 and buy 5D2 instead of 7D and 20/2.8. I tried the body, IQ is superb, but I didn't enjoy shooting with the camera. 7D is much more better in term of usability and AF. I found out when light is goog, than photo is good regardless used camera. Good light, solid tripod, focusing via liveview and careful postprocessing is the way to have a great photos.

What about noise when shooting with HTP=on? Does it mean when I shooting at iso1600 it's in fact iso 800 in term of noise? I have always set HTP on, because results look better for me. Some people claims 7D is too noisy but I happy with iso 1600...

Similar to primary issue. Picture style affects movie, am I right? There is no way to change it easily, right? So it's a good idea to have neutral style for still and some colorful for movie.

EOS Bodies - For Stills / Re: Upgrade from 10d to 60d or 7d
« on: August 27, 2012, 03:23:54 PM »
I upgraded my 30D to 7D this spring. I'm very very pleased, 7D is nice body, easy to use. I was afraid about weight, but the body fit my hand so good that it's no problem.

I considered 60D x 7D too, now I'm happy to choose 7D because of microadjustment. All my lenses 20/2.8 28/1.8 85/1.8 needed to be adjusted, especially the "soft" 28/1.8 became very sharp and contrast, very impressive change.

EOS Bodies / Re: 7d - max ISO issues
« on: August 27, 2012, 03:10:06 PM »
Hi guys, please how to setup min shutter speed on 7D when using auto iso? I need to keep 1/200s when shooting with 85/1.8 I'd like to use auto iso but it simply doesn't work as expected 1/focal lenght is offerred too often. HELP.

No issue found in my 7D.

Image preview is faster, image rating is fine feature, but too deeply nested, so I don't use it. Max auto ISO works as expected, but I don't use it because to slow times are offerred when shooting with 85/1.8, I need to keep 1/200s and faster, no way to set up it ;( I don't use any other new features.

EOS Bodies / Re: 7d noise question is it normal?
« on: August 27, 2012, 02:59:45 PM »
Thanks for description, I already found out iso 400 or iso 800 is the best. Last year I used iso 800 on my 30D every time when possible to get visually sharper images. I don't know how it worked, mayb similar to analog film, I love HP5+ film, it's grain made my photos visually sharper regardless fact resolution was lower than on FP4.

Iso 400 is used by 7D when shot with speedlite in auto mode, maybe the reason is because iso 400 is "native" value.

Monopod is a good idea, you can use your unpacked tripod by the same way (my way). I have no experience with IS, currently I'm waiting for 50/1.4 IS to feel the feature myself, I guess it will enjoy it very much.

With my 7D and 85/1.8 and cannot hold longer time than 1/200s, I shoot often indoor in low light when I come home from work and it's quite issue for me. Fortunately I can shot with 28/1.8 using 1/60s and faster.

Back to question. I love taking photos, regardless of used equipment and primes are my wins in point of value/price.

Right, L-primes are very expensive and heavy, fortunately cheaper siblings are good enough. They are special pieces of glass for special purposes, e.g. 50/1.2L, is definitely better at lot apertures than 50/1.4, the 1.4 is not good at f/2.0, the L is. At f/4.0 all primes are superb and compared to common zooms.

EOS Bodies / Re: 7d noise question is it normal?
« on: August 26, 2012, 03:23:34 PM »
I consider 7D noisy at every iso, my previous 30D was better in term of noise when viewing 100% raw files shot at lower iso. But noise is just one parameter of IQ, what about color, contrast, details...

But you can use SW to reduce noise and I consider noise of 7D images easily reducable, so I use iso1600 without any restriction, only when I shot at iso3200 I have to control exposition precisely. Adobe Lightroom is enough for me.

Do not look at images at 100% zoom, just print some photos on paper and feel it by hearth.

I use primes for following reasons:

- size and weight, cheaper filters (ND still necessary)
- big aperture = more lights for AF and viewfinder
- price
- easier to setup microadjustment

I own 28/1.8 and 85/1.8, both are excellent when fine tuned by microadjustment. Currenty waiting for 50/1.4 IS.

I dream about some lightweight zoom for EF-S with IS for video, e.g. 17-55/4.

17-55 is probably very good, but:
- too heavy
- too big lens hood
- too expensive

Hi, I owned 30D and upgraded to 7D in spring. I'm very satisfied, in term of noise 7D is one f-stop better, iso3200 is quite acceptable for me.

I feel 7D is noisy at every iso level, but it's possible to use software for noise reduction, try it!

7D is superb camera, noise is not everything. With 30D I had issue with AF in low light, also AF precision was not good. Finally I found out microadjustment very imporving my lenses.

Before with 30D: iso max 800, aperture almost f/4 to get proper focus.

After with 7D: iso max 1600, but I can use f/2.2 with my primes because I have better AF including MA.

I'm very satistied with 7D + 28/1.8 + 85/1.8.
