EOS Bodies - For Stills / Re: ISO TESTING, BY STUPID METHODS
« on: Today at 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: Today at 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.

Landscape / Re: Alaska mountains
« on: November 20, 2014, 03:02:38 PM »
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!

T

Some great shots. I agree B&W looks really good when done well, which it has been here. A wonderful knife edge arĂȘte 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.

Don't believe the 7DII misses the top exposure scale in normal modes. Are you sure you're not in one of the auto ISO modes that's removing the scale ?

Sporgon,
Your photos really highlight this thread.  And I'm not slighting all the other contributors here.  All photos published here are great and wonderful.
But Sporgon's just have an ethereal quality to the sunset that make me warm and fuzzy inside (why in the world do I say that??? ;D), and I really want to go to my own sunset in that kind of scene! 8)
I'll try to learn to get this effect in my photos in the future, what an inspiration!

Thanks Lion Rock.
Nice image, Sporgon. Is that your neck of the woods, or are you a music tourist?

 ;D  Thanks Nancy, are you referring to Benjamin Britten ? No I don't live near there, I'm in the North of England, and I'm afraid that Benjamin Britten is about the last composer I would travel to either listen to or haunt his local. Hope he wasn't a relative of yours ! My dislike probably stems from doing a Britten opera at school, Noye's Fludde, and it was just - well, noise !

If you are familiar with Aldeburgh I did a few panoramics which have been lost to filing and never used, so I'll show them here for you. They are actually sunrises but still in the spirit of the thread. The stainless steel shell sculpture caused a lot of controversy with the locals apparently. It has cut into it some of the lyrics from Britten's Peter Grimes: " I hear those voices that will not be drowned". I presume it is a memorial to both Britten and those that have lost their lives at sea working out of the fishing town.

You are outdoing yourself, Sporgon!
That shell is a true work of art. I hope you make money on shots like these - you deserve it.

Thanks Domino.

I got this effect by under exposing the sunrise and filling the steel shell with a touch of flash.

( I don't know where these red links have come from in my posts. I didn't put them there and they do not link to my work).

Many thanks Domino. Sorry I meant to reply to your kind comments about the Hay Wain picture. I'm pleased you like it because that lighting really appeals to me too. It is very different to the panoramic produced for National Trust, but then those pictures are really meant to show people the place and (hopefully) make them want to visit, rather than being 'artistic'.

Never made anything on the Aldeburgh pictures, but didn't expect to. Went there after Flatford. It's very difficult to make anything on landscape pictures unless they are specifically commissioned. Digital has inevitably devalued photography in a monitory sense, and raised expectations in an aesthetic sense.

And many thanks to rpt too !

In the spirit of our under exposed sunset theme I gave one of my Alde boat pictures a darker curve and then brushed back the boats.

I think it has improved it actually.

I love the reflection.  Beautiful.

Many thanks Click, Aglet & Lion Rock.
Sporgon,
Willie Lotte's Cottage is so beautiful, idyllic ...  I could live there and die there, and be happy!
You shot a wonderful photo with all the right mood.

Thanks Don and Click. Don , you are right. Under exposure can be very effective in these types of scene. In fact I tried re doing my picture from Flatford Mill - Willie Lott's Cottage where Constable painted his most famous picture; 'The Hay Wain', using some lesser exposed frames, and I think it gives a picture with good atmos.  ( It is a sunset after all).

Yes it is a very beautiful, peaceful place and has been well preserved by National Trust. It's not that dissimilar now to how it was when Constable's father owned the mill. except that the pond where he painted the horses and cart - The Hay Wain - is now about two feet deeper than it was two hundred years ago because that part of England is sinking !

When will I leave you alone? When you stop making what I see as outlandish or farcical claims that you either can't illustrate, make no difference to the actual images people shoot, or when you stop mistaking example Canon images for Exmor ones! I am not out to antagonise you, indeed you have sought out this contretemps, I have said I see myself a bit of a balance to some of the sillier claims (8"x10" prints) and to add a little to a few other threads.

You forgot to mention the bit about citing (blatantly) multiple exposure D800 pictures exhibited on 500px, as single frame exposures.........

Now that jrista has actually used an Exmor based camera in the field he must realise that he was wrong on this front, but hasn't admitted it........yet.

If your new 5D has the serial number beginning with either a 2 or a 3 then it will have had the mirror modification done whilst being assembled at the factory. These later ones also had a (slightly) improved rear LCD screen.

OOC jpegs are nothing like as good as the latest models, best to always shoot in RAW. It is capable of producing images well on par with the latest kit, but it is a light hungry camera; when shooting in low light it is best to over expose slightly, highlights allowing, and bring down in post. Maybe this is something to do with it having a QE of about 27%.

Regarding dust, here is part of a (small jpeg) frame on my 5D. The latest in camera sensor cleaning is so good .... now !

Check that the AF is accurate with very fast lenses wide open. There is no micro adjust, and mine was never quite right after dropping the camera.
