Canon General / Re: Does Canon really deserve this?
« on: November 24, 2014, 12:37:14 PM »
but the lens works so well on the 5D2.....

It is a case of the same lens being great on both Crop and FF and not having to buy a separate lens for both. I like how Canon can use FF lenses on it's crop cameras......

It's great if you use both "full-frame" and "crop-frame" cameras. However, for those of us who do not need *GASP* "full-frame", having to purchase "full-frame" lenses for our "crop-frame" cameras 'cause Canon neglected to cater to our needs, is bad economy: we pay for what we cannot even use.

Waste to use FF lenses on a crop frame Canon camera???  LOL Now I really have heard everything!!!  One of he great strengths of the Canon crop-frame line is that it can use the entire family of EF-S and EF lenses!  Moreover, issues like corner softness and vignetting either 'go away' or become far less acute.  AND my 100-400mm becomes a 160-640mm equivalent! 

Ah, the silly, silly things people complain about!  :o

Also due to the pixel densities of current crop cameras, and so the potential for resolution, these cameras need the best glass possible. OK so you lose some of the outer image circle, but as Marauder says, that has its benefits too. Producing lenses of this quality is going to be relatively large and expensive whether they have an aps-c image circle or FF one.

Face it, Canon, the "Rebel" line is dead, so bury it ... along with the 70D and the (still-born) 7DII. As for the latter (the 7dII), it is a weather-sealed camera, but has no decent weather-sealed companion lens!?

Odd my 70D is working out just fine and when I wear that out I'll probably go for a 7DII - which seems to be getting a great reception . . . I think it might be you that isn't listening to what Canon's customers are actually saying.

Technology has moved quite a distance since the previous decade and production cost have equally dropped. The question which answers my statement above, is why does Canon persist with a "crop-frame" line-up, especially since all their good lenses are "full-frame" stuff? They should just drop it and concentrate on "full-frame" exclusively: the 6D is a "Rebel", the 5D is the 70D, and the 1D is the equivalent of the new 7D. Only difference is in the size of the sensor and the price that is asked by Canon.

Also, anyone who today (or tomorrow) considers buying a "crop-frame" camera will also look seriously at the mirrorless offerings from other companies. Only in the "full-frame" segment is Canon still tops. So unless you have an investment in "full-frame" Canon lenses, which would make "upgrading" to a "full-frame" camera a financial no-brainer, Canon's "crop-frame" line-up offers very little to the enthusiast ... because if the enthusiast with a Canon "crop-frame" camera wants a decent lens, then a "full-frame" lens must be bought. This is very wasteful for the enthusiast - although great for the shareholders!

(Just to clarify, I am not saying that "crop-frame" is dead, just that Canon's versions thereof are well past their sell-by date.)

Hey Sella ! I thought you had sold up your Canon gear and moved to Fuji ? A Fujifilm XT-1 if I remember. A really neat little camera that has so much going for it - except it's not a FF 6D, with a crisp OVF.

+1 on the post above me. Horses can easily run faster than the 18mph that Sporgon said. Please exercise at least common sense. A horse cannot run faster than a human? Football running backs run at 20mph, and none of them will outrun a horse. And yes, various online resources rate the horse at around 45mph tops. Which makes the AF all the more impressive.

If only we had some photographic evidence. Oh wait ! We have  ;D

OK, in fairness Brian's example was to show the effectiveness of ten frames per second in capturing the moment of suspension in the horses's gait rather than AF accuracy with a target moving towards the camera, and ten frames per second has clearly capture the horse..... in canter gait, not gallop.  ;)

 I'll give in, maybe she had it up to 22 mph.

Incidentally I think the 7DII is shaping up to be a really excellent value top end action camera.

Well I hope Brian's knowledge of the camera is better than his knowledge of horses !

You might try reading the review before embarrassing yourself with a gratuitous negative comment.

"Perhaps even more beneficial for understanding what can be done with this frame rate is to look at a visual example. Drag your mouse over the labels under the following image for a visual look at the 10 fps rate. Drag your mouse completely across all of the labels in 1.3 seconds to get an idea of the speed of the approaching horse – approximately 40-45 mph (64-72 kph). I know, the labels are a bit small for that mouse move, but this approach happened very fast."

She would have to be riding a top form Derby winner - on the flat - on good going - with a race saddle - riding weight less than 7 stone. As I said, this target would have been travelling towards the camera at 18 mph max.

This is sounding more and more like a Monty Python sketch.

So apart from the best lenses, flash system, ergonomics, service, reliability, etc, "What have Canon ever done for us?"

Brought us the tiniest dslr ever ?  ;D

Monty Python's Life of Brian has to be one of the funniest films ever made. I never get tired of watching it !

That nag galloping towards the camera at '40 to 45 mph ' , who does he think it is,  Red Rum ? If a horse like that was really going flat out it would be about 500 metres per minute max - 18 mph.

http://www.cameraegg.org/rumors-5d-mark-iv-price-for-3799-to-be-announced-on-march-17th-2015/

Thanks for posting, but totally incredible as far as specs go. No 5D iii successor will ever only have 98% viewfinder coverage. And first the "rumor" says 2x CF slot, while a little further down the page it says "weight with SD card". Mentioning a specific price point so long in advance immediately and utterly invalidates any rumor, as far as i an concerned.

That said, i do believe canon has to come up with a 5d iv mirrorslapper some time soon and it better has a spanking new higher res sensor ... Otherwise they dont have to bother at all. I also expect it to not have 4k video. At least not internally, because canon will cripple away that feature to "protect" 1d c and c500 etc. I could well imagine that canon jacks up launch price to 3799 ... And get bitten by that decision. It would basically price the camera totally out of the enthusiast/semi-pro sphere .. Which accounts for probably 80% of potential sales of such a mirrorslapper. Well, we will see.

Me ... Not really interested any longer, if sony a9 is a killer.

I don't think the 5DIV will be a 'mirror slapper', or at least not if you don't want it to be.

With this talk of a 'modular' dslr going round I think the next 5D could have an interchangeable viewfinder, that is an optical pentaprism one for those that want to shoot stills with a high quality OVF, and an electronic EVF for those that want to lock the mirror up and use it for either stills or primarily video.

This way you get the best of both worlds.

EOS Bodies / Re: Canon 5DIV: 36 MP US $ 3799 TBA in March 2015
« on: November 23, 2014, 06:19:07 AM »
Personally I highly doubt the next 5D will be around 36 mp. The 5D is meant to be the ultimate general purpose camera. 36 mp means much larger files for little real world benefit.

Another mid twenties mp count with very high QE, saturation capacity, low light performance etc etc... is much more desirable for the vast majority of users.

The less than 100% viewfinder is a strange thing to add, makes me wonder if the next 5D will be the first camera to have an interchangeable viewfinder; one normal pentaprism, the other an EVF primarily for use with video. This would fit with its role as an 'event' camera when both stills and video are required.

By having interchaneable viewfinders the quality of the OVF system would not be compromised.

EOS Bodies - For Stills / Re: ISO TESTING, BY STUPID METHODS
« on: November 22, 2014, 04:30:48 PM »
It is certainly impressive for high ISO, but you were shooting in strong light (EV 12.3 judging by your exposure). Results from high ISO always looks better when shot in light that is bright enough to not need ihigh ISO. If you'd done this in low light then the difference would become apparent.

Agree with what has been said so far in response to the comparison; this is not a valid test - unless you are aiming to show the 7DII is better.

1: As has been said, the 24-105L at 100mm and f4.5 does not have the same sharpness and contrast as the 70-200ii f2.8 at 100mm at f2.8.

2: You shot the 5DIII at ISO 3200 at 1/125 with a focal length of 100mm, so at best for critical sharpness you were probably dependant on the efficiency of the image stabilisation. You shot the 7DII at ISO 2500 at 1/250 at 100mm, so much less dependant on the IS.

3: You shot the 5DIII at f4.5, the 7DII at f2.8 in relatively dim light, so the 7DII had over twice the (volume) of light reaching the sensor than (the crop area of ) the 5DIII. ( Bearing in mind exposure is calculated on light density, not quantity).

These three points are why you obtained the result you did.

1. I disagree that the 24-105 f/4.5L is any less sharp than the 70-200 f2.8L (Mark I) at 100mm. http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=355&Camera=453&Sample=0&FLI=5&API=1&LensComp=103&CameraComp=453&SampleComp=0&FLIComp=2&APIComp=0

2 & 3. And yes, in my initial post I noted that I would have preferred to compare the same lenses side by side, with the same settings. This was more of an "after the fact" attempt to compare images, as I wasnt planning this review during the shoot. In a next step, I will definitely be comparing the same lenses with the same camera settings.

Thanks for the input! It definitely helps with future videos and reviews, so I can provide better data.

Two apologise; just re read this and I see I didn't realise you were using the mki version of the 70-200/2.8 IS. Agreed, in the centre at these apertures the 24-105 is equal, possibly a tad better.

Also ignore my point 3, I think I must have been working on you having a longer focal length at f2.8. (The longer the lens the greater the volume of light that passes for a given aperture. So in this situation you would have been much better to use the 5DIII with the 70-200 @200, @f2.8, because although exposure remains the same, you would have had a much greater volume of light in your shot.)

I think we are really looking at point 2. 1/125 at 100 mm is risky for critical sharpness, 1/250 is much safer.

Lenses / Re: In praise of the 40mm f/2.8 STM
« on: November 22, 2014, 08:38:39 AM »
I too love this lens. Just disposed of it in favour of the new 24mm pancake, because my only body is now the 7DmkII and 24mm is a more useful focal length on a crop body. The new lens appears to be just as good.

I fondly remember the days of film and manual focus, there was a Pentax camera, the ME Super, which was tiny, and they produced the first pancake lens for it, which was a 40mm f/2.8. The combination was amazing. At the time I was already committed to Canon and rather resented that my camera was large and unwieldy by comparison. Finally Canon have given us a pancake lens - two even - but the days of tiny SLR cameras are long gone.

Actually cameras such as the Pentax ME / MX and the Olympus OM 1 / 2 were considerably wider than than the current Canon SL1 / 100D, a fraction lower in height, but obviously shallower due to no sensor. Weight was similar.

So you can still get a current, tiny slr, and it goes very well with the 40/2.8 and the new EFs 24/2.8.

I really like the 40 as a landscape lens, especially for panoramics. I try to avoid taking large, heavy gear into the field. A 6D + 40 pancake really fits the bill.

EOS Bodies - For Stills / Re: Sending my 7D2 back due to high ISO noise
« on: November 20, 2014, 03:14:42 PM »
but again I found myself learning the painful lesson of cropped sensors.

This is why I'm telling myself not to fall into the 7D2 trap as I did previously with the 7D. If you are really discerning, and used to full frame quality, there's no 'budget' option to get good quality 'reach' I'm affraid.

I bet the 7DII is a better contender for 'reach advantage' than the original 7D was. To realise potential resolution you need the capable optics, pixels, light, magnification, stability. The trouble with the 'crop sensor for reach' is that you only gain one of these; pixels. Everything else remains unchanged. The improved sensor of the 7DII with higher QE might make better use of its 20 mp, assuming all other factors are efficient.

The Moose's Tooth massif from the great Gorge of the Ruth Glacier. The gorge here is about a mile deep.  The really amazing part is the ice at this spot has been measured at 3700 feet deep!

Some great shots. I agree B&W looks really good when done well, which it has been here. A wonderful knife edge arête in the first picture. I have some 35mm trannies of traversing Crib Goch in North Wales during heavy snow. Must get round to scanning them, though North Wales is hardly Alaska, but then the pubs are much closer at hand when you get down.
