PowerShot Cameras / Re: G15 or G1X for my mom???
« on: October 31, 2012, 02:33:10 PM »
I
*  The new camera will be used mostly to take photos at birthdays, holidays, family vacations, and the kids/family dogs running around.
*  The new camera needs to have good ISO performance and/or flash performance for different lighting conditions.

Based on these criteria, I've narrowed it down to the G15 and G1X, and I'm leaning toward the G15, because the reviews I've read state the G1X has slow autofocus, which could cause problems when she tries to take photos of the dogs and kids running around. 

What do you guys think would be the best camera for my mom?

Thanks

I had both the G12 and G1X. Was not happy with either. Gave the G12 to my 62 year old mother for purposes similar to what you mention above. She never uses it unfortunately. Just was not intuitive to her I guess and she has a PhD so it is not a matter of intelligence. Even the G12 is slow to focus and not ideal for catching kids or animals. A lot of shots will be missed...

I got rid of the G1X as well. I loved its image quality and shots of adults or scenery were very good as long as I had a couple of seconds to compose the shot...Its autofocus was slow and time between shots was terrible. Enough to frustrate me and eventually dump it for 60% of what I paid for it...

Not sure if the Canon SX50 (Amazon link below) would be any better or not but you might want to look at it as well. Take your mom to a store and see which one she seems "comfortable" with. If she is comfortable then she will pick it up and use it. If not it will just grow dust like the one I gave to my mom...Good luck.

The SX50 is a larger and more bulky camera than the G15 or G1X and has a tiny sensor.  The extreme zoom sounds nice, but even with IS, you can't easly hold it still, so fast shutter speeds are needed.  As soon as you get indoors, its too dark to use it, and the tiny flash is inadequate, so a external flash is needed.  I'd only recommend the SX50 as a general use camera to someone who knows its limitations and understands how to work around them.
As a vacation camera to use in bright sunlight, it might be pretty good, or a camera to capture still wildlife also under ideal liighting I think thats its strong point.

Pricewatch Deals / Re: Deal: Canon EOS 5D Mark III $2799 from eBay
« on: October 31, 2012, 02:06:17 PM »
no, i'm pretty sure we've seen $2750 from adorama selling through ebay

http://www.canonwatch.com/deal-today-only-eos-5d-mark-iii-for-a-crazy-2750/
Yes, I bought mine for $2750 with free shipping and $56 ebay bucks which I used to buy a 2nd battery from Adorama as well.
Its been $2699 from a non authorized seller.

Software & Accessories / Re: LR noise reduction in comparison to DPP
« on: October 31, 2012, 02:03:51 PM »
One of the advantages that Lightroom has over DPP is that you can create a layer using the brush and apply NR selectively to that layer.  This allows you to add more NR only to the areas that need more.  Photoshop does this is a more sophisticated way, but its easy to do in LR 4.
 
 Some of the other NR software attempts to apply NR only in the areas where its needed most, and works in some cases but not others.
 
You can get free downloads of most of the common NR software and try it to see how it works for you.  Each has its own following.

EOS Bodies - For Stills / Re: 5D Mark III sensor cleaning noise (squeaks)
« on: October 31, 2012, 01:57:40 PM »
People can generally not hear ultrasonic tones, but they can dectect pulse trains at much higher than ultrasonic frequencies.  They sound like a chirp.
 
http://grouper.ieee.org/groups/scc28/sc4/Human%20Perception%20FINAL.pdf

This is a fascinating study, but it is not about detecting ultrasonic tones and doesn't really apply to the subject of ultrasonic hearing.  The study is about human sensitivity to and detection of pulsed radio frequency energy, an energy which consists of oscillating electric and magnetic fields that travel in free (empty) space without air.  This is the energy that, for example  lives in the Amateur radio bands, well above the FM broadcast band for example,  and well into the microwave region.  This is the type of energy that eminates from Television brodcast antennas, cell phone towers, cordless phones, your laptop's WiFi system, and microwave repeaters.  The study is not about ultrasonic "tones" and it is not about acoustic energy.


what is clear to me , based on the above, is that  (1) there is  a very wide variation from camera to camera structural resonances, and owner to owner hearing abilities,  with respect to what is actually heard during the cleaning routine, and (2) human hearing cannot possibly be used to measure the presence of or effectiveness of the cleaning routine because the cleaning routine itself cannot be heard!. If you hear something, then your ears are sensitive to whatever frequencies your camera's internal structures are vibrating at.  Thats about it :D .  Moreover, when you compare your audible results with someone else, then you are not comparing your respective cleaning systems, you are comparing your own hearing sensitivies and the natural structural resonances present in your respective camera bodies :D
No argument here, I was just pointing out that there is still lots of  things that we do not understand about hearing.  We do not even understand how bone conduction allows some people to hear ultrasonics, just conflicting theories that may or may not be correct.  I tend to believe the theory about bypassing the eardrum and directly stimulating the cochlea makes sense, since many animals actively hear and use ultrasonic sounds.  Others believe that directly stimulating the brain is making it happen, and of course, it could be harmonics being generated in the bone structure that vary from person to person.
Its almost certainly the pizzoelectric ultrasonic driver that excites the sensor generates many harmonics that some can hear.

Third Party Manufacturers / Re: Layer-based sensor patent by Sony
« on: October 31, 2012, 01:39:25 PM »
Canon has a similar patent as well, a couple of years old.  The issue is making one that is competitive.  With all the camera manufacturers hurting for sales, it would be a big risk to come out with something completely new, because people have stopped buying luxury items.
Most of the high end sales are in europe and the USA, and the storm on the east coast will be tieing up the money of many people potentially for years.  So, R&D keeps going, but production is going to be very cautious.

EOS Bodies / Re: Where the heck is the 70D or 7D mkII?
« on: October 31, 2012, 01:34:26 PM »
Its pretty obvious that there would be no 7D MK II soon, if ever after they came out with the new firmware.
I think that Canon has been working to perfect their new backlit sensor technology and will likely announnce something in early 2013.
This is just my guess, but it takes into account recent patents and news about additional sensor processing capabilities being added.
I'd much rather see the new technology than a warmed over 18mp sensor with Digic V

PowerShot / Re: G1x Vs. G15
« on: October 31, 2012, 12:35:48 PM »
I guess that the Adorama sale on the G1X is over.  On Sunday, I bought the $799 bundle deal they had which included printer, and software along with a $400 rebate. (Its back up to $1288 now)
This came out to $399 net, and I can sell the printer for $250 and the software for $30, so after thhat I paid about $120 for it.  If I like it, I'll sell the G11 I now have for about $300, and end up with $150 or more back from the deal.
Unless you are desperate, keep an eye out for more deals like that as the holidays approach.
I hope my camera did not get destroyed by the storm. Adorama shows it as pending, and shipping is likely to be delayed for a few days.  I'm in no hurry though.

PowerShot / Re: Hands-On Review of SX50 & Wish I'd Had it for Sandy!!!
« on: October 31, 2012, 12:23:01 PM »
Tes, please post your images.  In many of the news images, I noticed dozens of people holding up their cell phones or point and shoot bodies, and saw oen G10/G11/G12 like body.   
 
I'd expect that the SX50 would have difficulty in the low light, particularly if used with the lens zoomed out. You would need a fairly fast shutter speed if you needed to stop the action.   A camera like the SX50 works best in bright daylight.  Of course, the 7D also struggles a bit in low light when compared to FF, but would be many times better than the tiny sensor in a SX50.

In stock here. Norman Camera is one of the good dealers, and not impacted by the storm either.

Lenses / Re: focusing accuracy/repeatability on 50mm
« on: October 30, 2012, 08:37:46 PM »
The body is much more responsible for repeatability than the lens.  The 5D MK III and the 1DX are much better than older models.  Generally, the more expensive lenses are better, but there are exceptions.

EOS Bodies - For Stills / Re: 5D for a 1DS mk2 ??
« on: October 30, 2012, 04:13:26 PM »
I'd swap a 5D Classic for the 1DS MK II in a moment.  Its certainly not a even trade, 16mp rather than 12, much better AF, longer battery life, the list of plusses is long.
I'd have a hard time understanding why anyone would not swap.  If it were the 1D rather than a 1DS, then they would be equal.

Unless you know what you are doing and have the right tools (JIS Screwdrivers for one), you will likely cause more issues than you cure by disassembling a lens.
Dust is almost never a issue, but Canon will clean it for you.

EOS Bodies / Re: Cards for a 5D III?
« on: October 30, 2012, 02:12:13 PM »
You might get more images in a long high speed burst, and, if you have a fast USB3 reader, images will download faster.
I only upgrade in the event that I go for a larger card.  I just upgraded from three 60mb/sec 16mb cards to a 64gb 1000X card but its mainly because downloading of a large number of files will be faster.
Since I have dual cards now, I have a built-in backup so large cards are not a concern.

Lenses / Re: HELP - Which lens is best for blown-out white background
« on: October 30, 2012, 02:03:42 PM »
Wider aperture lenses are more prone to flare.  This usually happens because the lens accepts light from the sides.  I'd expect the 70-200 f/2.8 MK II to be the best.  The older versions do not have the best anti-reflective coatings. 
 
Since you did not specify the version for the lenses, I assume they are all the oldest version lenses without anti-reflective coatings designed for digital use, so try them all and see.
 

In any event, lighting is going to be the determining factor.  As long as you use soft lighting and the background does not reflect light at weird angles, it should be OK. I use flat black paint on surrounding surfaces to make sure that reflections from the sides are not a issue.

I use white velvet cloth as a background.  It is very good and is not reflective.
