old school: EOS-5  + 24-105/4L on Ilford XP2 super IS0400 Black & White film with Lightroom post processing.






Love the legs shot, very well done.

Also good to see the Bristol Fighter getting a viewing. I presume this was part of the Shuttleworth Collection at Old Warden.

After a disasterous start when they tried to use the rear gunner as the main armament the Bristol went on to become one of the most successful aircraft of World War One, a forward firing fighter like the other scouts but one which could protect its tail. Stayed in service after the war longer than any other aircraft.

I think this is the only airworthy one left, although much of a disassembled one was recent found in a barn, and the last I heard a consortium were boing to rebuild it to flying standard.

I know a little about these because when I was a young lad we had a family friend who flew as the rear gunner in one during the war in 1918 having lied about his age in order to join up.

My daughter's pet Polecat.

I always make sure she keeps it in bed with her when her boyfriends come to stay.

Lenses / Re: Making a perfectly sharp lens corner to corner idea
« on: December 30, 2013, 04:25:41 PM »

This brings up an other idea: How do medium format lenses perform when attached to a FF camera with an adapter, are they then sharp corner to corner?

To give you an idea; in the eighties I used the wonderful Pentax 6x7 system. The system was highly regarded in it's time. You could get an adapter to mount the 6x7 lenses into the Pentax 'K' mount for 35mm cameras.

I tried this with my Pentax MX, and the results were - disappointing !

Larger formats are much more forgiving of the lens yet it is a common belief among small format users that larger format lenses must be better.

The poster about the TS-E lenses is correct; they have a larger image circle when in the straight position.

So why introduce the 24-105 in the first place?

My only guess it were other times back then when Canon had a different marketing approach, they wanted a complete ff 5d2 solution with one lens to keep the system affordable. Not that everyone and his cat has a cheaper 6d ff camera and Canon is on the money grab they probably feel customers can be nudged into buying two lenses.

The 24-105 was introduced with the original 5D in 2005.

The 24-105 vs 24-70 L IS really is a matter of personal preference. Greater range vs subtly better resolution. I have both ( through Building Panoramics ) and I'm torn between the two. The new lens is definitely better but as a general purpose 'do everything' lens I use 105 a lot.

I'm guessing Canon were unable to produce the improvements seen in the 24-70 f4L if they had given it the 24-105 range without the lens having to retail as the level of the 24-70II.

Given the level of engineering expertise Canon has, I somehow doubt that - but I find it much more likely they want people to have more reason to buy a "natural" focal length addon of 70-200 or 70-300 ... with the overlapping 24-105 you can do ok, but as stated above a lot of times 24-70 is too short for a complete setup.

So why introduce the 24-105 in the first place ?

 I'm sure you're right regarding their engineering expertise, but would it be (financially) worthwhile for them ? That's the point.

Incidentally Roger at Lens Rentals stated he'd never seen a lens with so many element adjustments, so it's clearly a complicated little beast. I wonder if this convoluted set up is responsible for the early copies testing little better than the 24-105.

All the stuff I've seen on the Sigma 24-105 suggests they can't either.

A six frame panoramic of Aldeburgh beach at sunrise a few weeks ago. Shot on 5DII with 50mm f1.4 @ f11, 1/10secs and ISO 100. Each frame is the same manual exposure and there is no bracketing. Just used the full range of the DR, letting highlights go as far as possible in the exposure.

That's the way I like to do it too, but I shoot handheld though; f/8 will give plenty of sharpness and is below the Diffraction Limited Aperture (f/10.2 for the 5D Mark II). Was there a reason you were going for such long exposures? I find there's no reason to stick to 'just' 100 iso on this camera body. By the way, did you push the shadows in post or leave them as is? Lovely panorama by the way!!!

Many thanks. The lighting was a challenge but I got it balanced in the end.

Like yourself I generally try to avoid f11, but in this case I wanted the funny iron post with driftwood tied to it to be right up close in the foreground to give a feeling of depth. With the 50 mil set at about 8 meters the nearest focus is about 3.5 metres at f11 and about 4.5 metres at f8 and I wanted everything in sharp focus and the post was very close.

I was on my heavy tripod, an old Manfrotto 058, so one tenth of a second is not a worry. As regards ISO I don't want to be over 160 with the mkii, 320 is absolute tops - for this type of shot - for me. The 6D on the other hand is insane !

I do like the freedom of shooting panoramics hand held, but to get the same sharpness as from a tripod I need to use very fast shutter speeds, although having said that stitched panoramics are very forgiving compared with a single frame. 

Hope you're enjoying your new mkiii !

What's all this talk of CAs ? You guys don't know your DxO. In their wonderfully condensed measurement rankings the 85 f1.8 has less CAs that all the rest.

OK so they test in the dark, but hey so what !? It's a 1.8 lens.

6D Sample Images / Re: Anything shot with a 6D
« on: December 27, 2013, 05:57:01 PM »
Boats moored on the River Alde, Aldeburgh, Suffolk, England.

Shot with the 6D and 24-70 f4L IS @50mm. A four frame panoramic.

The IQ from the 6D is really first class and the high ISO capability is incredible. However I find the soft click stops of the two command wheels annoying. They are so soft that when working under pressure I can't feel them. I'm sure it has been done to differentiate between this camera and the 5DIII and 1Dx.

Canon General / Re: Darkening OVF without power

If the transmissive LCD negates the Dof characteristics and benefit of the Ec-S screen I can understand why Canon do not give a custom setting for it.

I don't think that's the case.  I tried a borrowed Ec-S, the VF was brighter with a fast lens, and the 'focus snap' I saw with the Eg-S in my 5DII was there. Chuck Westfall indicated to me that Canon could provide firmware support for the Ec-S, if they so choose.

That's good to know because it looks like the future of the OVF is going to include transmissive LCD of one form or another.

Merry Christmas !

On the subject of the translucence LCD, I wonder if this is the reason Canon don't support the Ec-S 'manual focus' screen in the 1Dx.

Nikon were using these way before Canon and I hated them. In those days I was doing mostly manual focus and although the transmissive LCD gave a bright enough viewfinder it was not sharp. Changing to the Canon 5D (and before that very briefly a Pentax K7), was a revelation, once again getting the crisp, sharp viewfinder.

If the transmissive LCD negates the Dof characteristics and benefit of the Ec-S screen I can understand why Canon do not give a custom setting for it.

In the same way I would assume that a 'hybrid' EVF is likely to give a poorer quality OVF.

Technical Support / Re: SPORTS WITH 6D AND FLASH
« on: December 24, 2013, 08:11:11 AM »
A kid asked me this: "I've been shooting with my 6d;70-200;and 580exii. My problem is how do I capture them running,dunking, etc if i can only set my shutter to 1/160 using my flash???!!"

What do I tell him? Pls help, he thinks I am a cool photographer but I really do not know how this works. I would love to help him and learn.  THX.

Depending on the distances involved I suggest you suggest to him setting his 580Ex to 'high speed sync' on the back of the speed light. He can then sync at any speed. Then shoot at the widest aperture that will give him his required dof as high speed sync does reduce flash output. Only use the flash to fill.

Or just advise him to crank up the amazing ISO of the 6D and forget flash altogether.

The challenge is the manual focusing. Shot wide open, the extreme sharpness exposes mistakes brutally. My capabilities in this department is not what it used to be, probably a combination of lack of practice and fading eyesight, so to get the best from it I need to practice quite a bit.

You may find you need to pair the lens with a 6D fitted with the 's' screen to enable you to see the true dof. However you might find the controls annoyingly soft after using the 1Dx and 5DmkIII.
