EOS Bodies / Re: Focus problems with the Canon 7DII?
« on: November 22, 2014, 02:15:22 PM »
So I had my first real run today with my Canon 7D mark ii and sadly, I have a lemon.

80%+ of my images are showing a focus point on Canon's ZoomBrowser, that were nowhere near where the camera confirmed during the shot being taken.

I'll be asking for a straight swap out, can't keep this body :(

Here's the best of an unsharp bunch

Focuspoints in zoom browser or DPP are not accurate.  They only give you a general idea of which point was active and where.  I wouldnt consider the camera a lemon because of a software issue.  More likely you need to micro focus adjust your camera to your lens.

Can I add lenses my camera doesn't recognize?

Have had my 7DII for 24 hours, playing with the raw the last few hours on LR5.7. I have to say I find it much better than my 7D. Maybe lab results show "just" a 2/3 stop improvement in quality, but in real life I find it so much more than that. I look at my 3200 ISO shots and I'm liking them more than anything at ISO 800 with my 7D. Besides IQ, I find it a great improvement, I will definitely be using it next to my 5DIII, something I didn't do with my 7D.

I echo your sentiments.

just got my 7Dii late yesterday evening and took a few test shots at about 10pm, in a room with a 60w bulb.

Setting at ISO 3200 and when I ran my standard noise reduction I use for my 500D, the noise cleaned up far, far better than my 500D would at ISO 800

Lenses / Re: Roger Machin shows new 100-400mm

Roger Machin is actually a very senior Canon official and highly knowleagable on their lenses and their bodies.

I'm attending the Cape Town leg of Canon's Roadshows Saturday coming and Roger normally gives superb presentations.

He is a Canon man and does plug their wares a little too vigorously but it is the only platform they have to address their clients en masse.

He is very highly respected down here.

EOS Bodies / Re: what is the body you want to see canon release next ?
« on: November 16, 2014, 08:49:46 AM »
6D Mark ii with 45 AF points, mostly horizontal for better portraiture composition.

I'd like RAW HDR file output with better DR.

Digital level, touch and swivel screen and another that will help deliver superb landscape photographs.

Here's a silly one, tell me what you guys think:

Internal hypo focal distance calculator that will create a horizontal line, indicating the focus point, for which ever lens is attached.

Lenses / Re: The Next L Primes
« on: November 15, 2014, 06:06:10 AM »
It's undoubted, that Canon will bring someday Cameras with more than 22 MP, maybe up to 100 MP in the next xx years. What then? Are the current zoom lenses as good to fill out 100 MP? I think not, but maybe really good primes are...

It's much easier to make a cheap high resolution sensor than it is to make a cheap sharp-as-the-sensor lens. As example, nobody expects lens prices & sharpness to follow the same curve as processors prices & sharpness.

[Actually, making a modern processor in mass amounts is so hard, most have dropped out of the game, forcing Apple to leave both Motorola and IBM in favor of Apple. Many of the workstations so popular in the '90s have disappeared or become niche, e.g. DEC VAX & Alpha, HP w/ HPUX, IBM w/ AIX, Sun w/ Solaris, etc.]

Which raises two questions:

1. How many photographers would be willing to buy not only a 100MP camera, but glass to match as well?

2. At what point will photographers understand they're stuffing their HDDs with over-sampled images, and what will they do at that point?

[I wouldn't be the least surprised if APS-C sensors already over sample lenses. DxO Mark scores the 200-400mm on the 7D at 10MP, and both the 400mm f/2.8L IS II USM & 600mm F/4L IS II USM at 12MP. This might leave room for FF sensors with up to 36MP, but 50MP or more? I don't see it.]

Are you guys saying that the current zooms are good enough for current and maybe next-gen bodies but that they may be shown up on bodies that could end up with many more MP?

Lenses / The Next L Primes
« on: November 15, 2014, 04:02:00 AM »
A Google search later, it seems that the last non telephoto primes lenses released, were the 17mm TSE, 24mm TSE and the 100mm L Macro in 2009.

I believe it's fair to say these lenses are extraordinary in performance, with few faults.

But I'm beginning to wonder, just how far Canon can turn up the performance dial for any new prime they intend to release?

When I began photography three years back, a common bit of wisdom I found was that primes are just better than zooms and this was due to the simplified engineering required.
Then along comes 4 zooms, 16-35 f/4.0L IS, 24-70 f/2.8L ii, 70-200 f/2.8L ii & the 200-400 that had reviewers saying something along the lines of "this zoom performs good enough to make me sell any prime lens covered by that range."

I'm paraphrasing there, don't sue me  ;D

So back to the subject of what a brand new prime could bring to the table.
1. Sharpness from corner to corner at largest aperture
2. Contrast
3. Autofocus
4. Colour rendering
5. Bokeh/Aperture blades
6. Image Stabilization
7. Size/Weight/Filterability

Canon's latest zooms are a strong indication that the engineering process has become highly refined and that the next primes should truly shine.

I feel that Canon's next L prime should be able to deliver astounding image quality and simultaneously consign issues such as jittery or slow AF, sterile contrast and any fringing to the past.

Gents, guide me a little here.

I noticed at least 5 of you put your cameras off when changing lenses. Is this critical for all lenses or just those with IS?
If one doesn't switch off the camera when swapping out lenses, can you damage your kit?

Thanks peeps

Makes perfectly good sense to me. I will adjust to it immediately

Thanks DominoDude
I don't think it's critical, but for me it's part of a good routine to switch off all electronic or electric equipment before any exposure of contacts or circuitry. Any well behaved routine is there, at least, for the purpose of lessening the risk of forgetting something important or damaging behaviour.
I also imagine that if I power down in a controlled manner, then I make sure that the camera is able to finish all ongoing operations. When it comes back up I would also believe that the camera has done all necessary POST routines to identify what is attached or inserted and how to treat and present it.
Fully possible to do all this without flicking power on/off, but through this routine you make certain you have control, and you lessen risk for sloppiness (inserting a card turned 90°, for example).

EOS Bodies - For Stills / Re: Recommend first slr

Honestly, I would recommend getting a Rebel and say a 24-105.

You can spend time learning how to control various things like aperture, shutterspeed, ISO etc. As the 24-105 is an L lens, you can then save towards buying more lenses.

I did it that way

Oh wow!

These are spectacular Glenn.

May I ask which lens you used and if flash was used for that owl shot please?

Great stuff

Lenses / Re: Critical View of 70-200 f/2.8 mkii+2xTC III
« on: November 14, 2014, 12:29:26 AM »
But to be fair, the 100-400 performs at its worst at 400mm.

Does yours?  Mine was pretty sharp through the range, if anything sharpest at the long end (where I used it most).   As I stated, mine were on par.  When I tested them with my ISO 12233-type charts (I have the same QA-77 ones used by TDP), the 100-400 was very slightly sharper.  In real world use (birds, mostly), there was no meaningful difference in IQ.

Keep in mind there is copy variation with lenses.  Check the three copies of the 70-200 II with the 2xIII on TDP's ISO 12233 crops for an example.

Hey Neuro

I own the 400 f/5.6 but I've used a few 100-400's as we're a fairly large birding community and we often look at each other's kit.

Some of the guys own the older models of the 100-400 and I've found on those, the performance at 400mm is not great at all. Certainly not L level.
Some have recently got into birding and they've purchased their lenses in the last 3 years at most. The performance is different at 400mm on these newer iterations. I've heard of "phantom" upgrades so perhaps that could account for the difference in performance.

Post Processing / Re: POLL: What picture styles do you use?
« on: November 11, 2014, 03:33:50 PM »
Bryan Carnathan notes in his review/preview of the 7Dii that he shoots in Neutral for a purer histogram then will convert in post before undertaking the serious post processing.

I personally use a custom setting as loaded by the head tech guy from Canon SA but I only use it as I was advised to.

I need to deep dive to understand these things better.

Anybody have a chance to compare this lens at 400mm to the 400mm f/5.6?

yes we all have a prototype but we are still under NDA.   ::)
Canon are making lenses with a Minolta mount?

Haha! Now I feel foolish! Especially with Jon_D's goo-goo eyes :D

I meant to ask how they compare via the MTF charts :D
