Canon General / Re: CPN Interviews the Men Behind the EOS-1 Series SLRs
« on: August 22, 2014, 02:25:52 AM »
I'm liking the AL-1. It's tempting to get one but I already have a full frame system at even lighter weight in my OM system. After owning my 6D for a while I can appreciate the benefit of a grip, but it's far less important when there is less weight to hold steady. If the 100D/SL1 had a deeper grip for heavier modern lenses, but was otherwise just as compact I would have bought one already.  I might get one anyway.

There is a place for heavy powerful tank like cameras for intensive use, but also for something easier to carry in a bag while going about other business. The closest I found to to that was the 6D, but would probably have gone for the 100D or A7 if either had existed when I was exploring the market.

I'm pleased to hear some of Canon's thinking. When they move forward, it tends to bi a big step like the 1987 Eos preceded by models such as the AL-1. I think that we are in a similar phase now.

Lenses / Re: Image quality with or without filters

The only time I have noticed the difference is when photographing through glass using my 50/2.5 macro to take photos obliquely through a London bus window. There's always an extra chance to pick up extra reflections and artifacts with extra glass ahead of the front element. A hood may have helped, but the lens doesn't otherwise need one because the front element is so deeply recessed. Apart from ND and orange filters for b&w film, I haven't used a filter on that lens since.

On my only weather sealed lens, I soon bought a Hoya HD protect (not UV) filter permanently in place. I can't fault the IQ with or without filter.

The irony is that they would let most small sensor super zoom cameras through.

EOS Bodies - For Stills / Re: Canon mirrorless: Status?
« on: August 18, 2014, 08:45:42 AM »
Is Canon working on another mirrorless camera to replace the M2 (even though the US doesn't officially have it)? The hybrid sensor in the M2 that had better high ISO capability and a good EVF would be enough.

If they don't then Rebel series cameras will become the bulky alternative to Fuji/Sony/Olympus/etc. The separate EVF for the G1X II shows that they have another ingredient in place for future mirrorless models. It reminds me of the messing around with autofocus before Eos was launched in 1987.

It will happen, it's just a question of when.

If Canon don't have something up their sleeve, the high ISO performance of the D810 will give them something to think about.

Hopefully Canon have also accelerated to a 2 year update cycle. Meanwhile, no other lens could match my 24 IS. That and the rest of my investment keeps we with Canon.

I now realize what a bargain I turned down recently. I was offered an Olympus OM Zuiko 1000mm f/11 at the camera repair shop when I had my OM-10 serviced. Only £1000 including original case and key.

I already have the adapter...

lensrentals should buy it... :)

about 20 of these lenses on the planet according

and outside? how many more?  ::)

That's a question for NASA and other space agencies.

Seriously, global demand could rise when commercial space travel becomes a reality.

On the other hand, if such a big player as Canon or Nikon would jump on the MF train that could really boost technology, in particular the currently mediocre high ISO noise performance of many MF systems (digital backs) could profit tremendously.

Have you noticed the new Sony MF CMOS sensor now hitting the streets and replacing the CCD sensors in most of the products you refer to? It's a little too early to see a wide range of reviews, but that should answer your misgivings about previous MF products.

eg 645Z at

Mirrorless cameras are typically 2/3 the weight of DSLRs, and much slimmer. It's only a matter of time before Sony, Nikon, Fuji or someone else offers this 44x33mm sensor in a mirrorless design, weighing no more than a 5D3. Of  course, the lenses will still be bigger and heavier than we are used to.

It could be 35mm full frame that gets beached by the alternatives of more compact (APS-C) and better IQ (cropped MF). I hope that Canon has something in the works for when they have developed their mirrorless expertise, but the right time is probably Photokina 2016 with a decent range of lenses by Photokina 2018. Meanwhile Im sticking with my 6D and FF 35mm lenses, but I'm conscious that my investment may not be for ever.

Lenses / Re: 6D+70-300 DO *vs* 70D+55-250 STM
« on: August 12, 2014, 01:05:53 PM »
I will explain :)

Lately there have been quite a few occasions I wished I had an unobtrusive telephoto zoom.  I have a 70-200 f/2.8L II IS, obviously not unobtrusive
-70-300L nice, but big and white
-70-200 f/4 also big and white
-70-300 non-L ain't too bad, but has dated autofocus I'm not a fan of
-100-400 big and white
-135L cant zoom; though if Canon updated this lens I might go this route anyway

So that leaves 70-300 DO on full frame, or 55-250 STM on crop.  I have two 6Ds but have been contemplating getting a 70D also for some time. 

I do know the pros and cons of each route, was just looking for opinions of others.

Not buying anything until after photokina as I want to see what the 7D2 looks like (and it will probably push down price of 70D).

I share your views about the 70-300L, and bought one despite the white paint. I have fitted a black lenscoat, which is partially successful in reducing the shoutiness of the big white look.

Before buying, I did try out a second hand  70-300 DO at a store. The sloppiness of the zoom did not even allow 300mm to be used when pointing the camera upwards. This was useless for me, because I prefer to zoom with my feet unless a jetpack would be required. A non-L 70-300 IS in the same shop was the same.

That did not bode well for long term ownership, so I swallowed my misgivings about the paint colour and invested in the L. The other downside of the non L is the rotating front element, making circular polarisers a chore, requiring a switch to manual focus to keep the front element from rotating.

If you already have the 70-200/2.8L IS II then I would veer towards the 55-250 STM and body to go with it. If the f/2.8 and FF serves its purpose for low light, the 400mm effective length of the 55-250 gives you twice the reach outdoors. That was a very close second choice to my eventual decision, even without already owning a big white zoom. You would also gain the third option of 70D + 70-200 with 320mm equivalent reach in reasonable light.

On the other hand, discounts and/or announcements are expected in a few weeks, if you have no immediate need.

Software & Accessories / Re: Any NAS Experts? quick question
« on: August 08, 2014, 08:47:53 AM »
i think the best way to go is to use a thunderbolt or usb3 external portable drive to store the raw/originals as well as the catalog/database of edits. the newer models have 2 hard drives in one enclosure in a mirrored raid in case one of the drives inside fails. just plug the external drive into whatever laptop you want to use and you have instant access to the latest files and their edit data (provided you have e.g. lightroom installed on both those 2 laptops).

if you are intent on using a NAS, it will be a better user experience to have that device on a dedicated gigabit ethernet wired LAN segment/subnet. configure the address manually on your laptops, without a default route/gateway. the wireless interface should be on a different subnet with a default route and dns server address so that it can access the access point or router and internet name resolvers.

so, get a gigabit ethernet switch, plug in the NAS to that switch, configure a private IP address (different than the wifi addresses) on the NAS, configure the IP's on the laptops within the NAS network address space (without default gateways), and then plug the laptops into the switch.

i think i remember that lightroom does not support network storage for files & catalogs but i could be wrong. and i don't even know if you're using that software or not.


I have just bought a Lacie 5 disk RAID connected over Thunderbolt, will report back as I migrate photos onto it. That gives 5 times the speed of a single external HD, in the realms of SSD speed. USB3 would be next best, but would be close to the maximum bandwidth that USB3 is capable of.

The downside of RAID set ups is that a 2 disk system is twice as likely to fail, and my 5 disk system is 5 times as likely to fail. The future is large capacity SSD drives, but it will take a number of years for the prices to come down far enough for a large and fast growing photo library.

The suggestion of mirroring the drives is a good one, and gives immediate backup in case of HD failure, but does bring the speed back down to that of a sigle HD drive. That may not be important, I have just upgraded my system for the first time in 7 years, and have futureproofed the set up as far as possible.

When my existing backup becomes full I will add a 2 disk RAID, probably as a NAS over ethernet - the speed limitation of Gigabit ethernet will not be relevant to backup storage. Hopefully prices will have drifted further downwards by then.

The Sigma 12-24 weighs 600g, the faster Nikon 14-24mm weighs 1000kg. An 11-24/2.8 would weigh more, and have an even more bulbous front element. Apart from live action concert shooters, does everyone want that added to the weight of the bag?

The lens patent we have previously seen makes more sense:

Here are some angle of views

First column is 35mm focal length then the angle of view (not half angle, full angle) for the vertical, hortizonal and diagonal dimensions.

Equations are straightforward.  Perhaps I should make an iPhone app.

   35mm V   35mm H   35 MM D
11      95             117             126
14      81             104      114
16      74         97      107
24      53          74        84
35      38         54         63
What would the angle of view be? Keeping tripod feet or your own feet out of frame could be a practical limitation, unless cropping to panorama format.

Thanks. An app would be a great idea.

There is a patent for an 11-24 reported in January. Has the source just assumed f/2.8?

EOS Bodies / Re: here we come, 6d AF problems
« on: August 06, 2014, 01:13:15 PM »
Have you tried using the same lens on the different camera? I've found that the older designs (eg 50/2.5 macro) focus better on my old Eos 5 film cameras than my 6D, but more modern USM lenses are great on the 6D.

Single point focus also means making sure that there is something to focus on exactly in the middle of the frame.

I think that Canon are asking well ahead of time, so that they can develop a sensor. In contrast, Nikon would be able to pull together a product far more quickll, by buying in a 50MP sensor from their usual supplier.

Canon have not mastered mirrorless yet (in my view, not until they have a built in EVF that I'm happy with), but must be wondering how to approach a repeat of the 1987 revolution. It will be a few years yet, but will happen.
