Lenses / Re: Obsessing
« on: May 21, 2011, 07:36:34 AM »
The statement "no measurable resolution" in a lens test to me means "its the worst lens we have ever seen but the company would sue us if we said that".

I understand why some might choose to ignore the more scientific gobbledegook of lab tests, but I take them very seriously. Not for me the fluffy "review" where its always described in glowing terms, I'd rather know upfront exactly what I'm getting, the good and the bad with no pulling of punches.

Lenses / Re: Current prices (UK Market)
« on: May 21, 2011, 07:28:52 AM »
Sadly I don't see prices coming down. Even after the present emergency situation in Japan resolves itself and they start getting back to normal, there will be an enormous backlog of stock orders to fill.

Add to that the fact that Canon are now busily engaged in an extremely expensive exercise redesigning the whole lens range to suit the newest generation of high MP sensors, Id suggest that prices will only ever increase from this point.

One word of caution regarding the 100-400L. I have one and am happy with it, but Canon have already announced their intention to produce a 200-560L using a built in 1.4x converter to reach 560mm. Assuming the optical quality is good enough I fully intend to buy one as a replacement for my 100-400 when it appears. Granted the new lens is not going to be cheap, but the 100-400 is an elderly design and is in desperate need of an upgrade. One solution in the meantime might be to think about buying "pre-used" (second-hand to you and me), that's what I did with mine and it was (and is still) in superb condition at half the new price.

Unlike others, I'm all in favour of as many mp as possible.

Me too :-). I think 40 - 60 megapixels would be ideal for full-frame 36x24mm sensors. Past that the sensor is too small to support it well, and resolution will be higher than needed for most applications. I'd like to be able to produce pictures that can fill a book spread at glorious 400 ppi, which current full-frame cameras can't because resolution is too low. If you shoot detailed landscapes today you'd want a medium format system, which of course are way too expensive for hobbyists. Anyway 32 megapixels is a step in the right direction from my point of view.

I read an interesting article on medium format sensors the other day. In it was a discussion on how many mp would be needed before the sensor outperformed the lens. Apparently Canon are said to be working on lenses for 36x24 "full frame" that will work happily up to 60mp, while on the Pentax 645 sensors would need to exceed 110mp before it becomes an issue. Basically, I believe that manufacturers will simply offer better lenses as the MP count creeps ever higher.

That same article was saying that in prints of A3 or bigger, the large MP sensors on good quality medium format systems produced a very obvious quality improvement over the 36 x 24mm "full frame" size sensors. Basically, bigger is still always better.

Unlike others, I'm all in favour of as many mp as possible. Storage is cheap and getting cheaper by the day. No, the only problem I have with this rumour is the very last line. I've been holding my breath long enough for the 1Ds mk4 and it's waaaaaay past it's replacement date. The only good news for me is that if the 5D gets 32MP, the IDs will get more. So the 40MP plus rumour is looking possible.

But if Canon wait much longer, they will have to withdraw it yet again because by that time even 40MP will be old hat. I fully understand the current problems in Japan, but don't understand why Canon had not finalised the specs for the 1Ds4 long before that and got it to market.

Canon General / Re: Renting lenses/body - who does it?
« on: May 19, 2011, 11:24:55 AM »
As Lawliet has just said - special, one off occasions.

I've rented an EF500 f/4 for a motor racing event, it cost me just £100 for 4 days and there was no way I could ever justify buying something that I'd use so rarely.

And thats true for us amateurs just as much as for the pro's amongst us. Doing the cost/benefit analysis may be easier without the accountant leaning over our shoulder, but much the same thought process goes on.

If and when the 1Ds mk4 ever appears, I might well hire one for a weekend to try it out before I commit the vast sums of cash.

Based on my own experience, locating a file on an external hard drive is only a couple of mouse clicks more than finding the file on the PC's own hard drive. Apart from the time taken to make those two clicks, it's no slower at all, so don't worry about it taking longer. One extra heart beat, maybe two and thats it.

"Technology tends to trickle down, not up".

True for everything except the 1D and 1Ds, Canon are very conservative when it comes to their flagship models. Probably right to be so, because the average professional wants a totally reliable product and is less bothered about the latest gimmick.

The "prosumer"ranges seems to be where Canon experiment. As a breed we keen amateurs love shiny new toys and have been used as tame beta testers for many years. I like to think I'm less of a "gadget man" than many, but even I am not completely immune.

Technology is advancing so rapidly that no solution is guaranteed to last even ten years. I've used CD's in the past and provided we retain the ability to read them in the future they are as bulletproof as anything else. By that I mean CD's have problems of their own, as does everything else.

I am currently using a dual RAID external hard drive system. But all I can offer is to keep you wits about you as things change and export your saved files to a newer system in good time.

It is a concern for us all. I read a while ago that if the human race was wiped out overnight, in 10,000 years there would be nothing left to indicate we were ever here with the possible exception of stone carvings. Electronic records would vanish in milliseconds, never mind thousands of years.

EOS Bodies / Re: 7D focusing question??
« on: May 15, 2011, 03:15:02 PM »

I've carefully examined all your examples and apart from random sharpness variations which I'd suggest are caused by hand holding the camera, they all seem reasonable. Certainly I have worse examples shot using Canon "L" glass handheld. It does not take much to just take that edge off. The only one I'd have reshot immediately would be the gym shot. 

Remember none of us stand still when we shoot. We might think we do, but in reality we all sway slightly.
To fully test for front/back focusing issues try shooting using a tripod, so that camera movement is completely ruled out as a possible cause. Apart from my motorsport images I use a tripod for everything, and for the bikes/cars I use a monopod! I've had too many otherwise good compositions lost due to camera movement.

As far as using DPP for noise reduction I totally agree Neuroanatomist. In fact I'd go further - it is also poor at sharpening in my opinion. I love it for RAW conversion and refuse to use anything else, but I have third party Photoshop plug-ins for both noise reduction and sharpening.

I tend to agree with the OP. Car manufacturers the world over are constantly making schoolboy errors when naming products and the same with boat names*. Uusing a numbering system, like Porsche and many others, makes a lot of sense.

*Embarrasing example: I once owned a small Caravela 25 sailing cruiser, coloured black and cream. I chose to use the Name "Pintado", which is a breed of Cape Petrel, as the colouring was similar and used an outline of the bird on the hull. Sadly I had not done enough homework: In at least one culture it was the name for chicken, in another wallpaper and there was even a rather famous "courtisan" by that name.

There have been dozens of cases like this due to marketing departments mess ups. I see no reason to tempt providence when a simple numbering arragement is so simple. 

Canon General / Re: Delays Abound?

I tend to agree with Rob. While Canon obviously did not know the future when they made the decision to pull the planned 1Ds mk4, it was still a big mistake then and subsequent events have only made matters worse.

Be honest, do you really think Canon have been selling the IDs mk3 in any quantity for the last 2 years? Unless forced to replace a defunct body, everyone with a serious interest in the mk4 has been busy holding their breathe waiting. This cannot make any business sense however you look at it.

No, with or without hindsight, the 1Ds 4 should have been released back when it was originally planned, then Canon would have bought themselves time to redesign the camera from the ground up.

I fully understand the reason why Canon and others might have to delay previously planned launches. What I do fail to grasp is why they choose to keep everyone guessing. It did not make sense before the disaster and makes even less sense now. Is it a peculiar Japanese trait?

I'd feel much more comfortable waiting for the 1Ds mk4 if I knew that it's specs were in line with my requirements. If they were not, I'd be able to look for alternatives but if OK, then at least I'd know that the wait was worth it.

EOS Bodies / Re: Ai Servo in low light
« on: May 02, 2011, 04:44:46 PM »
I assume everyone is aware that AI Servo is not designed to achieve a confirmed focus lock? If thats whats needed then AI Servo is not the right tool for the job.

Instead it is designed to do the best it can in the time before the shutter is released. So there are bound to be high failure rates when conditions are not good, low light certainly qualifies as one such.

EOS Bodies / Re: Digic 5 vs nikon lineUp
« on: May 02, 2011, 08:56:11 AM »
Canon have made claims for the next 1Ds along the lines of "Industry leading" dynamic resolution and noise control. I would assume that will trickle down to the rest of the range over time*.

I prefer Canon's current approach personally, high mp and crisp (but noisy?) RAW's. In their attempts at noise control Nikon tend to soften images in camera too much for my liking, I prefer to apply my own noise control remedies in post processing, but each to their own. I do admit my methods are time consuming.

*But then Sony will not be standing still either, the reality is that the high ground will be occupied by a manufacturer for fairly brief periods as others catch up and overtake. I don't see Canon or Nikon being able to dominate as they have done in the past. Sony must eventually want to come and play in their own right and it will become a three way battle.
