One of the many falls on the Aurlandsdalen hike. Canon 5DIII, 24-70 f2.8L II
Wow, interesting water.  It looks like a slow shutter for the falls, but fast shutter in front.  How did you get this effect?

I find the barn owl one of the more enigmatic birds. I've never caught an image of one that dose them justice but I'm fairly please with this one.


I like your image processing on this one. Nicely done Sir.
+1.  Lovely.

Great review!

Your reviews have always been good, but this is the best one yet! Congratulations on a job well done!
Yes, agree.  Thanks Dustin!

Lenses / Re: TAMRON SP 150-600mm F/5-6.3 Di VC USD Hitting Market

Why is there so much fuss about the quality of a $1000 lens that comes with a 5-year guarantee?

Cuz it's too damn cold and crappy outside to do anything else  :D

I'm thinking (hoping?) this lens will pleasantly surprise.

It will
Are you testing one?

EOS Bodies / Re: Change from T3i to 70d, or invest in a new lens?
« on: December 24, 2013, 09:07:51 AM »
Hi all!
I am new in this forum, I have just registered because I would like to hear your suggestions.

Last year I bought a T3i, together with a EFS 18-55/3,5-5,6  IS II and a EFS 55-250/4-5,6  IS II.
I really like it, and I used it a lot. I use it mainly when I travel, what I do very often due to my work.

I always liked to take photos, but I am not a Pro. Fortunately, this year I could save money to invest in my equipment. I thought I could buy a new camera - first I thought in changing to a full frame, but my budget is not enough. Then I thought I could buy the new 70d, as I could buy the body only and use my EFS lens. My idea is that after some time, I could start buying EF lens (70d supports both EF and EFS) and later on, I could change to a full frame (if I see I will really take advantage of the difference).
I would like to take better quality pictures, and honesty I don't care very much of new features as the built in Wi-Fi. Do you think I will get any difference with a 70D?

But I also thought that I could invest in a new lens instead of a new camera. I read good comments about the EF-S 15-85/3,5-5,6 IS USM. I would have a longer focal length lens, and wider.

I would like to hear from you what would you do - jump to a 70D or invest in this (or other) lens?

thanks!

Leo
I had a similar path - started with a T1i and the two lenses you mention.  I decided to spend on glass first - picked up a copy of the EF 24-105L (which is available much cheaper now).  It was a huge upgrade to the 18-55, although not quite as wide.  My next buy was a Sigma 10-20 f/4-5.6.  Then I bought the Canon EF 70-300mm f/4-5.6L, followed later by a Canon EF 100mm f/2.8L Macro. 

About the time I bought the 70-300, I sold the T1i and bought a 7D.  About a year ago I picked up a 6D and sold my Sigma lens because I now had the wide angle via 24mm full frame.  The Sigma lens was probably the biggest mistake I made in this progression.  I just didn't use ultra wide angle that much.

I now have the above Canon lenses and a 6D and 7D.

My intention was to spend on glass that would work on full frame, because I knew at some point that the price point of full frame would get to the point I'd jump.

I'm and amateur enthusiast, don't shoot every day, and love my current gear.

.... but, I've been told repeatedly that when someone KNOWS what they're doing with flash, you can't really tell they used it.  I've yet to see an example of that myself, but I've had my eyes open for it.  Until then, I prefer natural lighting.



So, window light, studio light, off camera Speedlite or on camera Speedlite?
I'll bite....on camera Speedlite bounced off a wall?

Why wouldn't we also expect ISO performance equivalent to the 6D (which is 3 stops or more better than my current 7D)?  With fast shutter speeds needed for BIF, I'd love to be able to crank up the ISO, rather than close down the depth of field.

Why not expect the sensor to have 2.56x more surface area?  That would give you the big ISO improvement you're asking about...  A 180nm process might get you part of the way there with a Canon APS-C sensor.  Until then, the great AF / fast fps / high ISO choice is the 1D X.
OK, thanks.  I'm not a physicist, so I really don't know the ins and outs of sensor manufacturing.  If I read this correctly, it's the sensor size that's causing the ISO performance of the 6D?  The current 7D has about 63% of the sensor size of the 6D, doesn't it?  Why 2.56x to get comparable?

Just trying to learn here.

A FF sensor is 1.6 times as high and 1.6 times as wide as an APSC sensor... the area is 1.6X1.6 times larger, or 2.56... the area of an APS-C sensor is 39% of the area of a FF sensor, not 63%.
Thanks!  Sloppy math on my part.  So the pixels on APS-C are a lot smaller than on full frame - that's why the noise is higher?

To  be technically accurate, the noise is higher on APS-C because the gain is higher (must be in order to produce the same ADU values after ADC). Think of an APS-C pixel like a FF pixel used at a higher ISO. On average, ISO 100 on APS-C is about the same as ISO 250-400 on FF from a noise standpoint. This is because the smaller pixel area means the photodiode area is smaller, and charge capacity in a photodiode is primarily based on area.
Thanks to jrista and Don Haines.  Explanations like this are why I keep coming to this site!

Thankfully, hopefully labeled 7DmII, I love my 7D

lets see a super high ISO which is workable, 15 frames a sec,  lots of good stuff..

canon blow the industry away by giving us a new world class sensor tech which will blow all full frame away.  Tuen up that tech in the ff and blow us away again...

hey a guy can wish can't he....

Sure. A guy can wish for all the stars in the heavens...and be disappointed. Just to be frank, and quite honest...if people didn't wind their hopes up so much for the absolutely unattainable, they might not be so disappointed when Canon releases something more, down to earth.

It really isn't that hard:

 1. 22-24mp APS-C
 2. 10fps
 3. Better AF system (repurpose 5D III's maybe?)

One might even get particularly hopeful, and wish for something not quite as likely, but still nevertheless more attainable than starstuff:

 4. 180nm Cu Lightpipe sensor design (we know Canon has it, they already manufacture with it for smaller sensors)

Now, I might be a little dismayed when I don't get #4, but I'll still be entirely satisfied with 1-3. Might try a little realism sometime...and end up happy and satisfied, rather than devastated when your lofty hopes are all dashed to bits.
Agree regarding wishes 1-3 above.  Why wouldn't we also expect ISO performance equivalent to the 6D (which is 3 stops or more better than my current 7D)?  With fast shutter speeds needed for BIF, I'd love to be able to crank up the ISO, rather than close down the depth of field.

I like the name 7D. It's so cheerful and full of vigor.  ::) ::) ::)

I feel the same way. Names are deeply meaningful, and just changing them for stupid corporate reasons cheapens them.
Yes!  Look at Infiniti cars now - what a disaster from a company that's trying to build brands against companies that feature the 3 series, E Class, etc.
