For what it's worth: I have found that bird shots over water happen to be extremely difficult for me to get great focus... and the further away from the bird the worse the problem is. This is a huge frustration of mine personally. I chalk it up to large amounts of reflection off the water and then the dappling of those reflections on the bird. A circular polariser has helped me a lot in the past. I do not have the same problems with birds that are not floating in a pond. I just have a very difficult time with what I believe to be the reflections bouncing all over the place and seemingly interfering with the focus system. I shoot with a 70D and the same lens you do.

Canon Rumors · Sep 2, 2015

<strong>TOKYO, September 2, 2015</strong>—Canon Inc. announced today that the Company is developing a high-sensitivity network camera equipped with a fast high-magnification lens capable of long-range color image capture even at night, making possible the viewing of subjects that the naked eye would have trouble discerning.</p>
<p>Amid ever-increasing safety and security concerns, a growing need for advances in surveillance systems has fueled demand for high-performance network cameras capable of clearly recording visual data night and day for such applications as urban surveillance and the monitoring of important infrastructure facilities.</p>
<p>Canon is developing a compact high-sensitivity network camera that will make possible the clear viewing in color of distant subjects even under conditions that would prove challenging to the naked eye, such as at night with few ambient light sources. The camera’s imaging capabilities will make it ideally suited for such surveillance applications as crime prevention and the monitoring of natural disaster sites, enabling the viewing of scenes during either night or day.</p>
<p><!--more--></p>
<p>Drawing on a range of optical technologies Canon has cultivated over many years, the network camera being developed will feature a large-aperture ultra-telephoto zoom lens with a focal length of more than 600 mm (35 mm film equivalent) that achieves a bright F-value of 2.4 to allow large amounts of light to enter. The lens will incorporate aspherical and UD (Ultra Low Dispersion) lens elements that suppress the incidence of chromatic aberrations, which become more prevalent as a lens’s aperture size increases, while making possible a compact lens unit. The combination of the large-aperture lens with a high-sensitivity sensor and high-performance image processor will enable the color recognition of a subject’s face at a distance of 100 meters even in dark environments with a mere 0.08 lux of illumination, roughly equivalent to the illuminance of moonlight. By comparison, conventional nighttime surveillance to date has only been possible within a limited range with the aid of infrared illumination, or by using a night mode that only captures images in black and white.</p>
<p>Through the combination of an electric-drive pan/tilt function that control’s the camera’s orientation with the ultra-telephoto zoom lens, the network camera will be able to fulfill a wide range of surveillance requirements. In addition to the monitoring of natural disasters involving rivers or bays, for example, the camera will be well-suited for such applications as urban surveillance from the rooftops of buildings and for identifying automobile license plate numbers on roads, not only during the day, but also in settings in which nighttime surveillance is required.</p>
<p>Canon aims to commercialize the new network camera in 2016. Through the enhancement of the Company’s network camera lineup, Canon will respond to society’s ever-expanding monitoring and surveillance needs.</p>

Just saw this over morning coffee...

No backward zoom ring to deal with...I wonder if the focus ring is backwards also???

I don't really see much point on an SL2 personally, you still need to keep the AF sensor and its not like the prism/viewfinder is that large anyway?

It would actually make a lot more sense on a cheaper FF camera I'd say, there your at least looking at the potential of replacing a much larger prism/viewfinder with a smaller EVF. The height of the camera could probably be reduced a good bit that way, maybe slim down the grip a bit as well and your not far off the A7 mark 2 bodies.

When did you last maintain the seals, and how old is your camera?

Click to expand...

I never maintained the seals (I don't know I have to)... the cam is from around 1995/1996. Does Canon still support the EOS1n with new seals?

The rubber will wear out over time, so a new 5d3 will endure much more than a 20 year old 1d. Not sure if Canon re-seals cameras.

I clean all seals from dust and other once every 4 months, and lubricate with silicone to keep them tight and flexible.

^Saw it, turns out they're bigger than I wanted them to be. I'm looking to add a 40-45mm but for my intended purpose, the 40mm pancake would still be best for me.

I'd love to see how these new Tamrons perform though, I hope they're both very good for the price.

Btw, $599 - 45mm.

I note the price of the new lens is going to be $1799 or over here in the UK... £1799. The current exchange rate is $1.53=£1. Canon are laughing at us.

Yes, they are, it's the same story all over Europe....

Click to expand...

That could well be a reflection on the cost of doing business in Europe too, well part of the price differential anyway.

Not playing politics here but I am European though I live in the USA, and I have no axe to grind. The States do not have the workers protection, minimum wages, healthcare, social services and lifestyle of Europeans, you pay for that in everything you buy as well as your various other taxes. On the other hand over here we pay less for goods and earn less per hour for our work (unless we are rappers), many people don't get paid vacation, workers comp is paltry compared to Europe, the 'minimum wage' is largely negated by calling people 'managers' or the massive exclusions to the laws, it might seem unfair, but I am sure they sell stuff for what they can. Look at the price of keenly priced competitive items like Rebel kits etc to see if there is gouging, the price of those is also parity, yet if they could sell them for less they would, they are the proverbial 'stack 'em high, sell 'em cheap' item.

Of course, but the 35 L II is waaay beyond the normal price difference, I think that's what upsets people.

Funny thing is, with the exception of the woman crying before her husband's grave, this is the first time I've seen these photographs.

Canon is still looking for situations where there might be a market. I think the whole photography industry is in the same mode, looking for something where they can use their expertise and will sell.

I'm wondering about the flight simulator market. 4K LCD panels have reached commodity status, and are likely 50 times less expensive. Would the extra brightness make a difference? Would a projector take less space?

Mt Spokane Photography · Sep 1, 2015

I'm not trying to be rude, but ... The first question that came to mind was "why would this actually matter to anyone?" I generally do not read the nomenclature on the lens, since it seems to have no effect on the photos.

Does that mean the end of Eneloop? That was part of the Panasonic takeover of Sanyo.

No, Eneloop is not Li-ON, they made in a different factory, and used for a lot more than cameras.

This factory made Li-On batteries, and they are likely everywhere sold under 100 different brand names.

Sanyo was a leader in battery technology when Panasonic bought them, but like everything Panasonic, they seem to have lost sales. They blame it on Korean manufacturers, but where does the blame really lie? I don't pretend to know. I have a Panasonic Led LCD TV which has a IPS Panel and is great, but they likely lost a ton of $$ on it. They invested and continued to invest in Plasma wile the rest of the world went to LCD. This put them on the brink of going out of business. It comes from not believing the customer or understanding the market. It can happen to anyone, Canon included.

I see the two listings you mentioned. The ABR Trading listing says that the box is sealed by Canon, whereas Baez said it was sealed and they opened it. Of the two, I would personally take the sealed box. If these resellers are legitimate, they probably just bought them directly from Canon's refurbished website during a good sale, and then they are reselling them on Amazon at a markup. I don't know if Canon's warranty would transfer to you as a result of it being resold - my guess is it would not, but that is a guess. I bought my 6D as a Canon refurb sold by B&H. I'm assuming the warranty is valid because B&H is an authorized reseller. These guys are almost certainly not.

Personally, I'd buy a new one for $1,399 directly from Amazon, or B&H, or Adorama. The $100 you would save isn't worth the risk to me. If that $100 makes or breaks the purchase for you, then you can't afford the camera regardless.

Canon Rumors said:

We’re told Canon is actively developing EOS M and EF-M products and 2016 will be the year they “get serious about the platform”. Multiple zoom and prime lenses are in the late state of development and announcements should begin in the first part of 2016.
We’re also told that an EOS M4 will be a global product and a departure from what we’ve seen through the first 3 iterations. There was no information on sensor size, but I suspect APS-C will remain part of the system.
It would be a great if Canon put real resources into developing the EOS M system.

Click to expand...

A few years ago they said they were "getting serious" about video, and look what happened there.

I strongly suggest no one holds their breath. This is marketing stop-loss drivel.

got a quote on that? and i'm talking about an actual quotation from canon, not a rumor from here or CW,etc.

Hi,

along with the recent anncouncement of this high ISO monster cam I would just like to ask the experts here in the forum,
what you think could trickle down into an overnext 1Dx, 5Dx body...Might we see a crippled 1 Mio ISO 1DxIII version along with a 5DV?
If so, they surely are in the concept phase of such a beast, while preparing the roll outs of the 1DxII and a later 5DiV/X whatever...maybe the rumored 5DC could get its share of some of these new specs.

Or will this tech remain within the 30K USD realm?

Click to expand...

as pointed out, big pixels are the key.

However if a foveon (layered RGB) arrangement of pixels is ever employed then it becomes relatively trivial to bin pixels together before readout as all pixels will be adjacent to same colour pixels. This is exactly what I do with my astro CCD camera when I'm searching for a target.. I have ~60% quantum efficiecy mono camera with 8x8 binning giving me ~45um pixels, it means I can clearly see and identify an object in a 1 second image that my eyes cannot see at all.

The reason binning works is that all the signal from multiple pixels can be added together pretty much noislessly.. it's only reading the signal out that adds noise.

Alternative routes to reduce noise also exist.

Look up EEV (UK sensor manufacturer). They do L3 sensors amongst other things, the idea is to add a photomultiplier prior to the readout amp. This reduces the effect of readout noise. Also look up ANDOR.. they joint forces with some other companies and created sCMOS.

The idea of sCMOS was to take a slow semiconductor process and optimise it for sensors, then produce an ultra low noise high readout speed sensor.. which they've done.

The sensor uses an ADC per row of pixels. As there are so many ADCs they can afford to run very slowly and still get a very high frame rate. Slow running means low analogue bandwidth, noise is proportional to bandwidth, so that means low noise.

http://www.andor.com/scientific-cameras/neo-and-zyla-scmos-cameras

Awsome doesn't come close... the cameras are out of this world.. if measured in ISO I'm sure they be into the millions.

I did get a quote for one for astronomy, but it was about £8k and I couldn't justify it.. but if I were a professional I might well.

DSLR Sensors have a VERY long way to go.. even the Sony ones..

Click to expand...

All though I do not understand much of the technical terms, I can see that there are innovative concepts out there. As you state according to your knowledge, it would be more than awesome tool to have such a sensor. My conclusion on this: To make it feasable for DSLRs I guess it takes another 25 years of development, maybe a bit less. By then I'll be in my early 70s...So this will be great for a new generation by then! Thanks everyone for their kind input on this. But anyway, a 12 MP lowlight cam at relatively clean 1 Mio ISO might be manufactured by then...who knows.

Click to expand...

25 years is not a bad guess for "I've just managed to record an image on a hunk of siliscon in a lab, at 10x10 pixel resolution and it blew up after 3 seconds of use".. to fully working DSLR at affordable prices.. the first Astro CCD image I came across was made in the late 1980s... and that sensor took time to design and make, which means the clock probably started ticking in the early 1980s.

The jump from what's at the bleeding edge of science cams to DSLRs ought to be 10 years or less away, the key is scalabilty; L3 (or EMCCD) cams are less suited as they really stress the silicon with very high voltages, but sCMOS is potentially very scalable...

As I mentioned it's approx a £10k camera now, in less than 10 years or maybe less than 5 we should see this sort of tech come our way.... If I were in Sony or Canons shoes I'd have been wining and dining the sCMOS people with a view to adding their tech to DSLRs since they came out about 3 years ago.... and they probably have been.

Note: sCMOS is a 33000:1 DR, that's over 15 bits.. Native!.. if Canon are borrowing this tech for their 5DIV/1DXII it's a Sony(Nikon) beater.

rfdesigner: thank you so much. this is great information...we will see. Hope they have been dining with the sCMOS folks... 8)

I hope we are not getting to the point where the floor for "L" lenses starts at $2,000. Honestly, I find nothing wrong with some of the older lenses I own: the 24-105, the 17-40 and the 100-400 for example. I'm worried that Canon is focusing to much on specialty lenses and not enough on general purpose lenses.

Click to expand...

Have to disagree. The 24-70 f/4L IS is a clear IQ improvement over the 24-105 and its included macro mode is phenomenal, the the 16-35 F/4L IS categorically runs circles around the 17-40 f/4L. And neither of those lenses are anywhere near $2k.

Click to expand...

Yes, the newer lenses offer significant improvements, I'm not arguing that. I'm just saying that the lenses they replaced were not bad lenses at all.

The 24-70 f4 "L" is superior optically, but you also lose 35mm in focal length.

Everyone has to make their own judgement call and prioritize their needs and resources. I'm just saying that I hope Canon doesn't go too far in their quest for perfect lenses and forget those of us who need versatility over perfect IQ.

Click to expand...

For them there are choices, don't get hung up on the 'L', the 35mm f2.0 IS is a superb lens; the 16-35 f4 IS is quantum leaps above the 17-40 and a comparable real world price, the 100L Macro is a decent upgrade from the non L version and not expensive either. The 8-15 f4 fisheye zoom was a bitter pill to swallow, the price was three times the predecessor for no gain in functionality for my personal use, so I didn't swallow it, guess what? The 15mm f2.8 fisheye still takes fantastic images just as it did before.

It doesn't matter what your personal need is, it is fairly certain you can find it within Canon's lens catalog either new or used, but people who are using the new sensors want and need lenses to match those capabilities and the cost of those lenses is going to be high.

I really like my 15 fisheye and it is better for me than the 8-15, I loved my 16-35 f4 IS but knew it would have to go after getting the 11-24, I am very glad Canon didn't stop at the 16-35 f4 IS, they could have done, but I shoot a lot of wide angle and have a need for 11-16 that I am prepared to pay $3,000 for, I appreciate most people aren't, but I say keep going Canon, just buy the best optics you can for what you need and if that means all your lenses aren't 'L's' then so what? Mine aren't and I don't care.

Just to tack on to the end of that - The way I see it is you have two or three levels of L lens in a way. The lower priced, older stuff which gets the job done such as the 17-40 and 24-105L, gateway L lenses for hobbyists with 6Ds and then you have the mid range L for the advanced 5D3 user and finally high end L for the working pros with the very latest cameras. More options is always a good thing and gives me something to attain to - like being worthy of even owning an 11-24mm! (Still working on level 2 - 16-35L!)

Anyone have a Sigma 24mm art 1.4 prime and a Sigma 35mm 1.4 prime? I'm trying to decide which to get for low light and some star photography too but I'm struggling to decide so if any of you have some experience with both which do you prefer and recommend for me?

Some info: Lightroom says 80% of my pictures are at 24mm and I'm looking for a good wide angle prime to go with my 50mm 1.2 and my 24-70 f2.8 but 35mm seems like a nice focal length to me as well as most of my photography is without a tripod and more run and gun Instagram style.

Also I'll be using the prime with a 5D III if that helps.

You may want to read this before deciding. The sigma 24mm has coma issues until f/2.8 for star photography. If you are using f2.8' might be better served by the Tamron 15-30.

The only 'negative' of the f2 IS is the strong vignetting on FF cameras wide open (which I actually kind of like and is easy to remove in post when I don't want it and is nearly as bad on the Sigma anyway), on crop cameras the effect is much more mitigated.

For me the choice was simple, reliable and consistent AF, universal perpetual EOS compatibility, and IS, over bigger heavier but one stop faster Sigma.

If you need the speed you need the speed, for some shooting situations the f1.4 is a necessity, only you can decide how critical that one stop is for your shooting situations, but don't think the f2 IS is a slouch, or that the f2 IS lacks character because it doesn't, just look at Dustin Abbott's review to illustrate that!

http://dustinabbott.net/2014/03/canon-ef-35mm-f2-is-usm-review/

Personally I find the IS more useful than the extra aperture.
