Camera focusing

There's a fabulous guide to the 1DX AF system and the only difference between it and the 5DIII system is the AF-point linked metering on the 1DX. Otherwise they are identical so this guide is equally valuable and pertinent to 5DIII users.

It sounds like you're referring to Spot Metering linked to any AF point, which is available on the 1-series bodies but not on other Canon bodies, where spot metering is limited to the center of the frame. I'd call that more of a difference in metering rather than AF systems.

The difference in the AF systems is iTR - face/subject recognition and tracking in AI Servo. As Canon puts it, on the page you linked:

" The only major AF-related difference between the two involves their metering systems. With the EOS-1D X, the new 100,000-pixel RGB metering system not only measures exposure, but can be used along with Automatic AF point selection to assist the AF system in following subjects around the AF area. This is Canon's Intelligent Tracking and Recognition system, EOS iTR. Backing up this sophisticated 100,000-pixel metering system is a separate, independent DIGIC 4 processor, dedicated strictly to metering tasks."

will there ever be CFast in DSLRs?

This is fascinating, Don! Thanks for sharing! I'd be particularly curious to see an updated version comparing, say, 7D, D800, 5D3, 1DX, D5300, etc., with film, to see how much improvement there is now over older cameras like the original 1Ds. Would the modern cameras show a resolution advantage over the older models with equal pixel counts?

I think that the real limit is the glass. People talk about the good old days, but the reality is that the quality and resolution of lenses now exceeds what was around in the good old days of film. As a group we like to fixate over the image sensor and we forget that a camera is a system, the image quality is a combination of sensor, lens, focusing system, image stability, AA filters, image processing, and speed.

Yes, Sir + 100 for me too. We need to see the whole system plus, we, as Photographers, We must improve our Photographic Skill too.

Lastolite Hotrod Octa / Striplight softboxes - are they good?

I have the 12x48" Hot Rod Strip Box (and a couple of their Ezyboxes). Although it's not as easy to set up as the Ezybox (they call them that for a reason!), it sets up pretty quick (it's more work to assemble the first time you set it up) and the stripbox is robust (it comes with a swivel mount, but I usually use a Manfrotto 026 which is sturdier). It's great on a boom over a group portrait, for example.

For a 36" octabox, I'd be a bit worried about using just one speedlite due to the larger surface area (close to double the area of the 12x48" or a 24" square soft box). You might consider one of the Ezybox II Octas (31" and 40" versions available), which can take the quad bracket so you can use 1-4 flashes in it (or adapt it to a monolight).

Sigma 105 F2.8 EX DG macro OS

Sigma 105 F2.8 EX DG macro OS was somewhere out the lights, because the lens price was too near to 100L.
But about 2 months ago Sigma drop the price in USA and Europe and now it's much more interesting. I bought one and I'm impressed - 100L is slightly better only with focus speed and accuracy.

Here is my review (translated) - http://translate.google.com/translate?js=n&sl=auto&tl=en&u=http://nonchoiliev.com/blog/935

Advice needed: Mobile Flashlight device

What are you looking to do to the light? Soften it? Restrict it's spread? More specifics would help.

Honl makes a nice system of modifiers for speedlites, which attach via a rubber+velcro band that goes around the flash head (just straps on, no adhesive). They have short and long snoot/reflectors, grids, gels, etc. Lastolite has a similar lineup with their Strobo stuff, which can mount direct to the flash head, or via adapter to the bracket/'speedring' that comes with the Exyboxes (the latter means nothing is directly attached to the flash head, all the weight of the modifiers is on the bracket and you just mount the flash to the bracket).

Zeiss Otus 85/1.4 coming in 2014 + wide angel to follow

I've been keeping up to date on this family of lenses when Zeiss initially started talking about them. I just drool whenever I first saw it and even blogged about it. I'm quite certain the wide-angle lens is going to be a 35mm. They already have the crazy 15mm. The best in it's class. So it makes sense if they do the 35mm.

I'm glad they are getting closer to a release date for the 85mm. I'm sure it's going to be nothing short of amazing :D

More dead pixel problems for canon

The forth body arrived today and has been returned. It had several red and blue pixels and a small cluster of stuck pixels. Again these were not obvious untill I went looking for them in long exposures. So after all the swapping it seems the origional body had the least issues.
Thanks for all your advice. I will have to deal with the issue by either shooting in raw or by using the long exposure noise reduction. My only other option would be a lighting rig and a scaffold tower.

EOS 7D Replacement Coming for CP+? [CR1]

DanielW said:
Something just occurred to me now... How likely is it that a new 7D will have many advantages over the current 5D3?
Possible advantages I see (sure many debatable):
- Crop factor for birding, wildlife and sports
- Compatibility with EF-S lenses
- Built-in flash
- Higher burst rate and bigger buffer
- Price
Is that it? I am aware, from reading previous discussions here, that the crop factor is not a huge advantage (if at all), and compatibility with EF-S lenses is probably not relevant. The built-in flash may not even come with the new 7D anymore, and some people even dislike it. Burst rate, well, here I see a difference, but it is not important to me (I understand other folks may need it, though).
Anyway, when the 7D2 finally arrives costing US$ 2,000-2,200 body only (more? less?), how much will a 5D3 be costing? I have just found prices under 2,900 on canonpricewatch.com, and rythercamera.com has the 5D3 for 2,499 right now. Even Canon sells it refurbished for under 2,800.
What do you guys think? Will the 7D2 be worth buying when the price of the 5D3 drops even further? I am not so sure anymore.
Cheers
Daniel
I can see some advantages in a future 7D mark ii, over 5D mark iii, but image quality at high ISO should not be one of them. I am an advocate for APS-C, which has real advantages for me. But if you expect a big improvement in high ISO, I recommend going with current full frame cameras. I like the depth of field of APS-C, and the size, weight, and more compact lens, and lower cost. But do not believe in big improvements in high ISO without a revolution happening in image sensor technology.

A New Rebel for CP+? [CR1]

I almost bought the Canon Rebel t2i over my 50D. Rebel is nothing to sneeze at. It's a damn fine camera. Any Canon DSLR. I was at Best Buy the other day and playing with their SL1. I would love one of those little guys!

Oh not at all, the rebels are fine cameras, no ones sneezing at them or anywhere near them it's just the way that they are "upgraded" is very humdrum and not worth getting excited about! We'd rather hear about a 7D replacement than a new rebel. Just more curious about the higher end specs.

I started out with a t2i myself. Gave it to my GF to use when upgraded. Still work flawlessly after years of service. I have nothing but respect for my humble rebel. I learned a lot from it. I actually get annoyed when people under use it or never use anything other than the kit lens. It's so cheap that almost every ones got one. Trouble is they don't all get the most of this amazing machine! Shame really as it can take stunning pics. That's how I feel about the EOS M too. I reckon in the right hands it can do wonders.

Those are really good cameras when in the right hands, indeed. I just feel they are a little too small for my hands. To be honest, I fail to see much advantage in the reduced size of the SL1, since it will not fit in a pocket anyway.
Daniel

Ultimately it was the small size of the rebel that made me want to go for a bigger model. Taking 1000 shots in one day gave me cramp! The first time I held a 7D was like finding a perfect fitting glove! The 5D2 feels good too but man the 7D just begs to be held! And then there's the shutter sound. Rebel is like a cat sneezing. The 7D is a deep satisfying cough!

I'm weird about stuff like that! But hey if you're not comfortable with your gear you won't wanna use it right?

I agree - when I was looking for my first dSLR, my hands just didn't fit the rebels, otherwise I would've bought a rebel. The 40D felt so much better ergonomically, and the 7D somehow improved what I thought was practically perfect. The 7D shutter also sounds much better than the 40D or the 5D2 - both the older cameras sound very clunky. Now I hate using the 40D in church or events because of the extra noise!

Canon 6D with Yongnuo YN568EX & YN622C Help??????

Hi,

I'll try and help with your question about your wireless triggers, although it might help others if you could break down your question (sorry, this could just be me).

In regards to your yn-622c wireless triggers they should work straight out of the box. In regards to powering the wireless triggers on, I would recommend that you power them on in this sequence:

If you are using off camera flash (therefore you have 1 trigger on the camera and 1 on the flash), turn the camera on first then the trigger. For the flash - attach the trigger on the flash then turn the flash on first then the trigger.
Then you should press the test button first (few times doesn't hurt), before you use them.


I'm not sure what you mean about turning the camera to wireless, do you mean wifi mode?

Also how many flashes are you trying to get firing at the same time and are you trying to do any ratio modes?

Hope this helps in some way?

Canon outperforms Japanese peers in patents, again

Patents are the result of R&D that a company paid huge amounts of $$ for. They may file for a patent, but not put it into production for some very good reasons. Usually, its a matter of production cost. A patent might produce a wonderful lens, but if it costs $150,000 a copy to produce it, then it awaits some new manufacturing technology.
I'd say that a patent is a way of protecting those millions of dollars spent in R&D. Most Japanese companies share patents or sell rights to use them, so I see no issue there. If you want to use something that another company paid to develop, you owe them some money.

I finally get my new Canon gear this weekend

This is a useless post except to say I'm excited about finally heading across to the US from Canada and picking up the Canon 6D and lenses I ordered some weeks ago from BH and Adorama. Looking forward to getting back into full-frame and trying out the Voigtlander 20 especially, as well as the 50 2.5 macro. Some obscure lenses that I have a feeling will really perform well. The 40stm and 70-200/4is everyone already knows are great. I'll start shooting and posting soon!

The Unthinkable: Swapped out 5D3 for 6D

Canon1 said:
John,

Now that you have had almost 2 months to shoot with your 6D do you feel that you ultimately made the right decision?

The simple answer would be yes....for now.

While I do miss the 5D3, the 6D has not stopped me from accomplishing the things I need to accomplish. There are definitely times when I do miss the AF system of the former, but not to the point where I'm going to lose any sleep over it. For the time being, I can get the job done with the 6D AF system which will suffice until Canon puts out another FF option that lures me into an upgrade.

I haven't really had any instances where I missed the other key downgraded features although I'm sure I will at some point. Although I will say there was one instance where I could have probably used the 1/8000th.

I still haven't really utilized the wifi features very much as I don't really like the UI vs the Camranger.

My initial impressions regarding image quality and workability of the RAW files in post still remain.

Other notes:
After replacing the focusing screen, I have been using my manual lenses a lot more.
As minute as it is, I have noticed the drop in size/weight which inclined me to purchase a 40mm pancake. The combo is actually pretty compact considering what I used to carry around.

Also, my original intention was to start swapping stuff out and selling so that I could create a new 1Dwhatever fund. That has since been derailed as I just picked up a Fuji X-E2 with 35/1.4. Assuming this works out well, I suppose it will only further convince me that I made the right choice as I picked up the combo for basically the difference in price from the 5D3 to 6D plus a couple hundred bucks.

All in all, I still believe it was the right choice as I will now have a new toy that I will hopefully love without having spent anything,

CES 2014. Nikon D4s is a fact. What can be expected from Canon?

GMCPhotographics said:
It's funny when Nikon and Canon trolls go to war over announced cameras. I just sit back with some pop corn and watch the fire works...or I get out and do some shooting :D
My first camera was a Canon AV-1 (manual focus, and Av only). I chose Canon becuase that's what my Dad used and I could borrow his lenses. I've stuck with the brand for my whole life and I've never looked back. For me operate a lecia, Sony or Nikon is like handling aline technology....I mean after all, their dials go the wrong way :D

sigma 15-30

Has anyone tested this lens on full frame? (specifically 5d3)

I really want a super wide (something 16mm or wider) but I don't really want to spend to much as generally I only use superwide to exagerate perspective / fun creative shots rather than serious landscape or architecture.

I've seen a preowed copy of the 15-30 for £140 and wonder is it cheap because its rubbish?

Any opinions or sample shots would be really appreciated.

For those who have to send the camera away for cleaning, how do you pack it? And then how do you ship it (UPS, FedEx, next day, etc)?

I've never shipped a camera to Canon, but I've loaned a 7D to a friend. Wrap it in bubble wrap, then place that in a box large enough for a few inches of packing material on all sides. If sending to Canon, do not include anything but the camera (no battery, no strap, etc.), ship it with the body cap installed.

Ship UPS or FedEx so you can get a tracking number that means something (USPS reports delivery, but does not actually track regular shipments). Enter the proper declared value and pay the insurance.

Probably a little late here, but it is worth mentioning that all of the freight companies have packaging guidelines.

If these packaging guidelines are not followed, the freight companies will not pay out on the insurance that you paid for in the event of damage. Actual loss is different if the package is not recovered. I have received "improperly packaged" damaged freight that was insured (and coverage refused) and have had packages outright disappear from UPS (only once, but I would have been SOL if I didn't insist on insurance from the shipper, and the investigation took a month).

If you do not have a shipping account, insurance gets expensive pretty quickly. In my experience, the local shipping depots in the strip malls mark up insurance rates 2x over doing it yourself online (which are still overly expensive retail rates), as long as the coverage limit isn't reached. UPS, USPS and FedEx all have insurance limits for online transactions and UPS has additional forms that must be filled out by a UPS employee once a certain threshold is reached (route driver or UPS depot- the strip mall centers don't count).

The replacement value of a 5DIII and a 70-200 II lens can come close to the insurance limits for retail customers.

Big companies shipping expensive stuff may not insure the packages- they have separate insurance to cover loss and the cost of shipping is exceeded by the cost of the carrier insurance rates.

For those that ship camera stuff regularly, it may be worthwhile checking into a shipping rider for your insurance.
