Craig, totally bummed out to hear about your business loss. I hope the Police nail whoever is responsible for the thefts.

A 50/1.2 would be roughly equivalent to 85mm, f1.8/2.0 on FF - couple that with the compact size of the an M-mount and that would be a sweet/compact combo in low light or for portraits.

I do agree on longer focal lenghts, and bigger lenses, but there is still something to do, and as you mentioned, it lags especially at primes. I want f/1.8 M primes! Small 12mm, 32mm and 50mm primes. (35,50 and 80mm FLs).
Agreed. Something like a Fuji 56/1.2 equivalent would round this out as a nice compact portrait kit. The kit lens has you at 5.6 when at 55mm - making the next town in focus ;)

PowerShot Cameras / Re: S120 Successor?

The time between new models seems to be increasing.  There is typically little difference other than a few features. 

Canon has said that their high end point and shoot models are doing very well, particularly the super zooms.  I expect to see more in the $500-$800 range.

Are you referring to the G1X line or the SX line?

Typically a new S series comes out every September/October.

I don't recall anything being announced to succeed the S120, have any of you heard anything of a looming release?

Thanks in advance

Perhaps Photokina then... Don't know if I would pick one up or not - really liking the EOS-M for most casual situations but it would be interesting to see how they evolve the line.

Nailed it at 1.4! Great shot!

Thanks Jamsey! It was the only shot I took also. 50 Art is such a killer lens.
I tested the 50 Art over a weekend but not with a moving subject moving toward or away from me at 1.4 - again you totally nailed the focus!

Here's a shot from earlier today, I have rediscovered hard light, and I love it!

Two Canon 600 RT bare bulb to the back left at 1/1 power, zoomed to 50mm. Triggered by the Canon ST-E3. Sigma 50 Art at f1.4, iso 100, 1/8000s.

Nailed it at 1.4! Great shot!

I have bought and sold tons of stuff on CL with no issues. There is also a local meetup group that has a buy and sell with similar good results. Finally, I have bought three or four times from Fred Miranda and the community over there is excellent - they have very high standards and a grading system for used gear. Like eBay, you get to rate both the buyer and seller.

Lighting / Re: large softboxes for speedlights - what are you using

Can you define what you mean by limited budget? Where are you located? Phottix make some inexpensive modifiers but I don't think they are available in USA due to patent issues with Westcott.

I have never heard of this issue but mine I did a shutter button fix by pouring alcohol through from the battery compartment - it has worked perfectly ever since. The shutter button essentially needed way more pressure than it otherwise would to trigger the shutter.

^^ 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.

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!
