EOS-M / Re: Need help.. LCD turns on but black!?!
« on: July 21, 2014, 01:44:54 PM »
^^ Interesting issue indeed. And the fact that you have had the camera for some time and know how it should operate is good information.

Have you tried a battery and lens pull (meaning removing them and letting it sit)?

Have you tried cycling through the 'INFO' button?

Reviews / Re: Please help me love ef 35mm f2 IS vs 40mm pancake
« on: July 20, 2014, 10:09:07 PM »
Interested to hear the outcome of this - I have the 40 pancake and am considering adding the 35 F2 IS to the collection.

If you aren't using FoCal or the like, you could try the Dot-Tune method to validate your AFMA numbers.

EOS-M / Re: Next official EF-M Lens

One slight frustration with the EOS-M system is the currently three different filter sizes across four lenses - is that really necessary ?
Agreed - this is certainly a pain. Even if you buy a CPL for the biggest lens you still would need a step-down ring for the others which adds bulk. I would imagine they made the lenses as small as possible to keep weight down hence the three sizes.

Admittedly I have not looked into Speedboosters but I wonder how they increase stops of lights passing through them? Changing perspective such as what an extender does I get but extenders degrade the amount of light rather than boost it.
A teleconverter enlarges the image projected by the lens. This is much like moving a projecter further away from a projector screen - much of the image is missing from the screen, and even though the quantity of light coming out of the projector is no different, what is on the screen is bigger and dimmer.

Do it the other way only works if you're using a lens designed for a larger format. It telecompresses the light into a smaller imaging circle, producing a brighter, smaller image. Same concept as a projector throwing out too big an image for a screen, so you move it closer.

Obviously using a larger projector screen (read: sensor) in the first place would have captured the same quantity of light, even through the intensity per unit area on the screen (sensor) is lower.

Or a different way of looking at it is the focal length has changed due to a teleconverter or telecompressor, but the physical aperture still has the same diameter. Therefore the aperture ratio (f stop) has to change.

A telecompressor is just a way of using a smaller sensor to do most of what a larger sensor would do with that lens natively. Even though numbers all get shifted around (focal length, aperture ratio, ISO, but not physical aperture or shutter speed), the end result should be the same (presuming the telecompresor ratio is that same as the crop factor, and you tweak all the settings to create equivalence).
Much clearer now - thanks for this!

I have had good luck and fast speeds with the Transcend USB 3.0 RDF8 for $14.95.

Not bad.  A few months back I picked up a San disk 32 160mb/s for 119 and I though I got a good deal... then the price kept falling and I kept price matching... my final price was $92ish... that was a good day.

Stark contrast to my 32GB (90MB) Extreme Pro I picked up shortly after getting my 5D3 two plus years ago - I paid $159 if memory serves me correctly. FWIW, the card is still a rock solid performer.

EOS-M / Re: How Much Would You Pay...
« on: July 15, 2014, 01:08:10 PM »
I would pay $799 for a revised body with EVF and way better performance such as shot-to-shot and AF speed and shutter lag. This would be in line with the Fuji XE-2, although the Fuji glass is still way better IMO.

With the latest telephoto, I would guess that Canon is done with M lenses.

Do you think they are going to kill off the M line?

I read in another thread elsewhere that the Kirk PZ130 works well too and it does not interfere with opening the battery door either.

OP: Good review, thanks for taking the time to write it. My M c/w 22 and 18-55 is my new 'goto' travel kit leaving the 5d3 and 24-105 at home. In the past I have always tended to have 15 pounds of 'just in case' gear on my shoulder or back on vacation but I have done a couple of recent trips with only the M and have been satisfied with the outcome. The lack of EVF/OVF is an issue in bright sun and I am learning techniques to work around them...

the other what a fun power management with the M is.
Do you mean the poor battery life of the M?

I don't use UV (protection) filters on my 40/2.8 pancake or on my EF-M lenses, but I do on the all the others that take them.

This is my exact scenario too.

Mikey from lightenupandshoot.com used to live in Columbia - check out his site, he is a very friendly guy and will give you tips on travelling there. Contact him through his site, I am sure he will respond. He taught me years ago in Toronto on one of his travelling road shows - solid guy.
