30 second exposure, Tokina 11-16 at 11mm and F2.8.... sometimes you need all the light you can get...

and yes, I have the 10-20.......at home.... in a box....


if you are interested in "portraits/landscapes/street ", the 11-16 might be a bit wide for you..... Personally, I prefer the 17-55F2.8 for that......

10-20? you mean the 10-22mm from canon? but isn't the 10-18mm having the better reviews from the two?

Oh and by the way, i'm only shooting in Crop( 70D ) so the range is actually a bit fine. Right?? sorry still a newbie.
OOPS! I meant 10-22.... good catch!

I've never used the 10-18 so I can't say anything about it.....

BTW, have you ever played around with stitching images together to get a wider field of view? I do that all the time when my lens isn't wide enough....

Canon EOS M3 Review by Dustin Abbott

In fact, the output from the M3 is better than from my 70D and close to my 6D bodies.

That surprises me. I though the 20.2 MP DPAF chip would be better in 'IQ' than the newer 24 MP rebel one.

There's a 1.5-2 year gap between the 70d and M3 release which could explain the improvements.

+1 The images are noticeably cleaner from M3 vs the 70D, and I noticed the same of the M1 vs the 60D.

ok this is actually not that hard

Yea, only takes like 15 pages to explain ;D

Yes, but 11 pages were about noise not increasing at all at higher ISO's.

This thread was derailed on page 3. Were at the part where the authorities come out and try and figure what went wrong and clean up the wreck.

The wreck has already been cleaned away, but there's still a lot of rubbernecking going on

The one thing Apple understands is photography

Thank you for your reply.
I still don't really understand why it is more convenient - how can it be easier than taking a CD off the shelf and loading it into the CD player? To me this is the biggest advantage of CDs - they are physical items that you can see and touch, not a file buried in some complicated computer file store.
The point about having a backup is interesting, but as second hand CDs are so inexpensive now I usually just replace any that are damaged or lost.

I generally buy CDs...and rip them to flac immediately and put the CD on the shelf for storage.

I keep the higher fidelity FLAC files on my media computer in the living room, for the "good" stereo...tube amps, Klipsch K-Horn speakers...etc. I like to play from my media computer, makes making playlists easy, etc.

Also with the files coming from a computer, you can avoid some wow/flutter type problems you might have with a cheaper cd player...and with my computer set up, I can set up my own high end DAC before it hits the amps. (That's actually a project I'm working on)...

I also make lower quality mp3's for my portable players...for the gym or car which are some of the worst listening environments on the earth, even if using pretty high end headphones.

and as for selling and "having to erase" for copyright. I guess I'm old school. I don't buy anything that I'd ever sell again. I guess I'm more of an old school guy in that to me, music isn't disposable.....that might be the reason I don't find much modern music to be worth buying, but that's another thread entirely.

:D

cayenne, someday you and I are going to have to meet.... (very similar interests, etc... old school for sure!). Seriously.

EVF idea for DSLRs - Hot-shoe ad-don EVF compatibility

One thing it would do is give canon an idea for the real world demand.

Personally I don't want one. I like the zero latency and zero power consumption of an OVF. I do like a fine ground screen, so an electronically switchable screen would be nice (I think there was a patent for this recently)

Where I CAN see an advantage is in having an EVF for when the mirror is up, so when you're shooting at 25fps in your 1DxII (one can hope) it then switches to EVF and shows you the last photo just taken allowing you to see properly and meaning you can keep the mirror up between shots, so potentially increasing the fps, if the ADCs and readout circuitry is up to it. (maybe 25fps isn't so outlandish then)

Point is a bolt on EVF probably wouldn't help in this regard.

7D II vs SL1/100D?

I think that you should keep the SL1 for discrete shooting and sneaky concerts, and pickup whatever body your budget will allow. A second hand 7D goes for fairly cheap - even better if you have friends, borrow one and see if you are happy with the image quality of the older gen model.

In other news, the thought of a 100D paired with a 100-400L is making me giggle.

7D user - advice on my best option for a 'go to' lens?

jimc8p said:
Hi

I'd like some advice on which lens to get for my 7D.

Canon EF 24-105mm f/4.0 L IS USM

Canon EF-S 17-55mm f/2.8 IS USM

I'm torn between these two because I don't know which one will suit my style more. I have been used to a 17-85mm f/4.0 kit lens and a 50mm f/1.8, both of which I'm selling. I'm concerned that the 24-105 is slower and will limit me with depth of field and low light shooting. And the 17-55 has less reach and may be less of a future investment as an EF-S. Here are a few details about my photography...

I think I'm quite lazy about the technical side of things, and like to keep gear as simple as possible. I don't mind small losses in quality or control for the sake of convenience (eg. staying with my 17-85mm lens for years before getting the 50mm). I like being zoomed in rather than zoomed out. Being wider than my 17mm shots has never seemed necessary to me. I like shooting in low light, and I like shooting with shallow depth of field. I think I will be sticking with my 7D for a while, and I will be getting the Canon EF 50mm - f/1.4 USM. Below are a couple of links to my stuff for reference.

Any advice greatly appreciated!


----Sorry, moved this from the Rumors forum

I picked up a tamron 16-300 the other day mainly for video use but it seems to have pretty good iq considering its range. I would not hesitate to use this where iq is not of highest priority, nor where you are shooting in poor light. However for an all around lens thats weather sealed its a pretty decent value. You might also want to consider a fast prime to go with it for those not so ideal conditions.

its all about the 5DS, who is using the 5DR

Your assertion that "no chance of any external manipulation or hidden settings such as what got me on my first go around with in camera settings" is invalid, the WB settings difference proves that.

The only way you can view native RAW files is in something like dcraw, short of that you have to know, definitively, which tags any individual viewer will honor.

Well i agree on the viewer part. However the WB setting was internal, not external and was my fault for not checking that. Still i dont think it has much affect on the noise reduction....but who knows what the digic is doing.

WB is not "internal" to a RAW file, it is a tag attached in the embedded sidecar file, if a viewer is honouring WB information it is reading that sidecar file, who knows if it is honoring NR tags and or reading the embedded jpeg?

In truth the only relevant comparison is a fully and optimally post processed file vs another optimally processed RAW file both to your personal specific end uses, and coming from different cameras would imply different processing for each to achieve optimal. To be sure 'RAW' is pretty meaningless, it is only the end result we can achieve with that data that is relevant.

Ok so i can buy the concept that what i may be seeing is an embedded jpg image. So in that case the comparisons here are still reasonable, just not pure raw. Only the one pair had NR applied, the rest had it disabled. The original comparison was that the 5dsr would have less noise because it is a full frame sensor and the attempt was to show that the same subject at the same distance on the 7d2 would have similar noise levels as the 5dsr. Both sensors share the same pixel size. From what i have been seeing, the noise is not less on the 5dsr. The pattern is different and perhaps easier to reduce algorythmically.

If you were to change your distance such that the subject filled the frame on the 5dsr, yes the noise would be smaller and less visible. I actually wish instillhad my 5diii to compare as well. It shoud fair a stop or two better due to its larger pixel size.

Anyway, in end as you say, its the finished product that matters the most, no matter how you get there.

Sony to Acquire Toshiba’s Image Sensor Business

SPKoko said:
After:

Sony sensors are now their own business


now we learn that:

Sony to Acquire Toshiba’s Image Sensor Business for $165M, Report Says

How do you think that this will affect Canon and us as consumers? Should Canon give up and start buying sensors from the now almost-sensor-monopoly as it will be impossible to compete with them? Should Canon raise their bet and invest tons of $ in R&D to be the only real alternative/competition to Sony?

You are thinking that Sony's sensor market is all about DSLR's?

Its about phones, 7 or more sensors in a car, sensors for appliances, homes, everything imaginable. That's why Sony split it off into a new business, they see the sensor business to be far larger than the relatively few DSLR's being sold.

Canon is not in the sensor business, except as making them for their DSLR's and a few High End P&S cameras. They have mostly sourced many tens or hundreds of millions of small P&S sensors from Sony since the beginning. Those LCD screens are from Sony as well. The camera business in Japan is very intermingled, with manufacturers selling parts to each other. P&S lenses are also a commodity, and often the same lens assembly is used in multiple makes of camera. Only the high end P&S have a Canon made lens. Nikon is said to farm out production of their P&S cameras. It is a complex tangled web.

24-105 lens error - Canada Repair?

My 24-105 has started to consistently show an error code (can't remember which one). All my other lenses work fine so I'm assuming it's a problem with the lens.

I took a look online at Canon CPS for Canada services which shows different levels of service. It's $100 a year which gets 20% off repairs and free shipping. The quote for one lens repair is about $260.

The single lens repair still seems to be the better deal since 20% off of $260 PLUS free shipping is less the annual $100 annual fee.

I'm just wondering if I'm missing something and if someone can speak to their experience with Canada repair services. I live in Vancouver.

Damaged 70-200 2.8 II, suggestions

I just had to repair mine after another photographer friend borrowed the lense while we were photographing a pro soccer match and he dropped the lens and camera off his monopod. Tiny scratch on the front lens was the only visible damage. I sent it to CPS and they replaced the front element unit and determined the IS unit was broken as well. The cost was $1168 with a CPS Platinum discount. The lens is less than a year old, with no other potential damage, so I'm certain the is was damaged in that fall.

Best to send it to Canon CPS toget a thorough checkout. Be prepared for a hefty bill. Suck it up. It's a great lens. Sorry for your problem, though.

I'm glad my buddy paid the repair bill due to his negligence in dropping the lens. That would get expensive in a hurry.

Cant seem to find if this was posted earlier so I'm going to put it out again. Canon has not widely advertised this. No fancy fliers in the boxes, no pop up ads when you register your new purchases online.

Starting October 11, 2015 through January 9th, 2016, Canon is offering a 13 month CarePak for free for select lens and body purchases from authorized dealers. This covers things like water damage, accidental damage, priority service, lemon replacements, etc.

I wouldnt have known about it until I saw it on another blog site.

The activation code is simply the items serial number.

5Ds (R) in crop mode vs 7D II

The 5DS R is a Frankenstein mix of the 7D II and 5D III with a larger sensor. The pixel pitch is the same as the 7D II, so in crop mode it's essentially the same. I rarely shoot in "machine gun mode", so the fps doesn't matter. I do like the ability to do more than one creative crop from a single frame and still have plenty of pixels to work with.

The other nice thing is panoramas. Normally I'd shoot 4-5 frames with overlap in the vertical. The 5DS R will provide nice results in one horizontal shot. When you figure the overlap and how many pixels your actually using from each frame, it's about a dead heat.

Toshiba To Sell Sensor Business to Sony

HTML:
From Reuters:</p>
<p>Toshiba Corp is set to sell its image sensor business to Sony Corp for around 20 billion yen ($164.68 million) as part of a restructuring plan laid out earlier this year, sources with knowledge of the deal said on Saturday.</p>
<p>Toshiba, whose businesses range from laptops to nuclear power, is undergoing a restructuring after revelations this year that it overstated earnings by $1.3 billion going back to fiscal 2008/09.</p>
<p>Image sensors, which are used in digital cameras and smartphones, are part of Toshiba’s system LSI semiconductor business. Toshiba plans to sell its image sensor manufacturing plant in Oita, southern Japan, and pull out of the sensor business altogether, said the sources, who declined to be identified.</p>
