EOS-M / Re: EOS M Lens survey - your favorites, and your most wanted?
« on: March 25, 2014, 02:14:35 PM »
I was going to ask for a good/fast UWA prime, but now we have the Samyang 12mm f/2, which I'm considering depending on IQ/reviews - could make for an awesome camera/lens combo for landscapes/nightscapes while backpacking (I'm crossing my fingers for good coma correction @ f/2-2.8).  My only EF-M lens at the moment is the 22mm f/2, which is a great lens regardless of price/size - it's IQ puts pretty much all the EF-S lenses to shame.  Other than that, a cheap, compact, fast 50mm equivalent would be nice.

What does "30 AF points" mean in the context of a mirrorless camera?

With an SLR, it's how many linear arrays are on the AF sensor (and their corresponding optics, of course), but if it's contrast-detect, you can define the area of detection anywhere, and if it's dual-pixel on-sensor PDAF, you've got millions of "AF points" which can be aggregated in a myriad of different ways.

So I'm back to what does "30 AF points" mean?

I assume it means that there are a small number of on-sensor phase detect points, similar to what we saw in the EOS M/SL1/T5i sensors.

NFC? Why? I guess so I can "bump" my phone/tablet up to the camera to transfer an image? Seems like something that could be covered by WiFi. Feature creep?

NFC would be for faster/easier pairing between phone and camera, the data connection itself would still be wifi-based.

Scored another 600EX-RT for $342; you can never have enough of those things.

EOS Bodies - For Stills / Re: when are the best Sales on 5d Mark iii?

Just after Christmas last year was when I bought mine, the 5D3 kit w/ 24-105mm f/4 was selling for $3300 and came with a 6% reward from Amazon - I don't think the kit has been cheaper than that yet.  I've seen the body sell for around $2500 new at ebay (at around the same time as when I bought my 5D3 kit), not sure if that was with a US warranty or not, and those sold out very quickly.

So, I have a Canon 600EX-RT and a Canon ST-E3-RT.  I have to say these are great and have had a lot of fun getting into off camera flash.  But,…I would like to expand to 2 or 3 more flashes.  Does the ST-E3-RT work with any Yongnuo flashes or does anyone think this may come around in the near future,..or am I going to have to get more 600s (ouch,..$$$!)

I don't know much about the prospects of compatibility w/ future yougnuo flashes, but as far as buying more 600-EXRTs goes - if you are patient/internet savvy, the cheapest option would be to buy them refurbished from the Canon direct online store when they put refurbs on sale.  I bought all of my 600's for a little less than $400 each ($373 before tax w/ free shipping) using a page monitor plug-in for chrome browser to monitor in-stock/out-of-stock status during sales (the app checks for changes in the web page every couple of minutes and I get a notification if a change is detected - so I pretty much know immediately if an item I am interested in comes back in stock or goes on sale).  I'll probably regret giving away my secret, but... screw it, I have pretty much all the gear already.

EOS Bodies / Re: 7D vs 5DIII default sharpness
« on: September 15, 2013, 10:29:22 PM »
7D has a rather strong AA filter - all the other bodies I've owned (T1i, 5D III, EOS M) have been sharper at the pixel level (edit - I only shoot raw, btw).

Lenses / Re: Filter for 24-105mm
« on: August 18, 2013, 12:23:46 PM »
I you are going to do a filter, I second the B+W MRC F-pro 010M (the $72 model you listed).  Multi-coated filters eat less light than single-coated and in my experience the B+W's MRC are easier to clean than the Hoya HMC's (I have one of the Hoya HMC's on my 100L - I don't like it much because it is a pain to clean compared to the B+W F-pro's I use on all my other lenses).  No need to get the slim filter because vignetting shouldn't be an issue on the 24-105mm (also, the lens caps on the slim filters can be a pain to take on/off and generally aren't as secure as regular lens cap, either).

Well, I'm disappointed with all the rumors coming out that this is just a derivative of the 70D sensor... was really hoping for a new, smaller fab process with next-gen IQ, starting with this camera. I really have no interest in the dual pixel AF, to be honest, and I can't imagine the sports/wildlife portion of the 7D's target market really does. Maybe I'm wrong, it's probably been discussed elsewhere... oh well.

10FPS sounds good, 12FPS sounds like it'd be shut down by the marketing team... New Phase AF sounds good, too, as long as it's a step up from the 7D and not a step backwards. Although by the time this camera is actually available I'll probably have the money for a 1Dx and it'll be irrelevant anyway.  ;)

I find it pretty likely that the 70D sensor already is using a smaller fab process - at least it definitely makes some noticeable strides in low ISO shadow noise - there is no more banding, judging from the RAW's I've reviewed, and definitely some increased headroom in when it comes to pulling shadows from low ISO RAWs.  Give me that plus pro-grade AF and 10-12FPS in package smaller/more affordable than the 1D series, and I think you'd find quite a few buyers right there.

EOS-M / Re: Returning M today...
« on: August 06, 2013, 02:45:33 AM »
I had a somewhat different experience with the RX100 - the rather poor corners at wide angle eventually got to me, and the low ISO performance of the RX100 Mk 1 is definitely not up to the same standard as the APS-C sensor of the EOS M - the Sony RAWs are noisier at base ISO.  The bokeh from the RX100 lens wasn't great either, occasionally hazy is probably a good way to describe it.  So for the types of shots I like to take - low ISO/optimal aperture - the EOS M delivers better output when I have the time to set up the shot.  I find the 22mm f/2 to be a very decent lens, other than the CA in the corners (super easy to fix in photoshop), and the extreme corners aren't perfect (but they are pretty good and notably better than my RX100).

The RX100 definitely has the edge in size, AF speed - compared to DSLRs, the AF in the EOS M just feels brutal in certain situations, comparatively, the Sony can't track focus very well, but the one shot AF mode is speedier and more consistent compared to the M.  It's about even on ergonomics, the EOS M controls feel a bit more initiative to me (probably because I'm already very familiar with Canon DSLR control schemes), but the RX100 is is much easier to operate with one hand (after you've installed a Richard Franiec grip, that is - Richard's grip is fantastic).

I'd be willing to give the RX100 series another go once Sony updates the lens, but probably not before then.  I still like the camera, too - it's likely the best pocketable compact on the market and a great option for many (did I mention it does great 1080P60 video?) - just after an extended audition, I discovered that I'd rather have a better lens than what the Sony offers.

As for the M - it does some things well, but it's a few tweaks (needs a better location for AF-on mapping, better grip, and a second control dial would be nice - maybe something like the G12/G15 implementation) and a great AF system away from being a truly great camera.  The IQ is great, and although the native EF-M lens selection is limited, the options that we do have are very good.  When I'm using the M I can't help but think how much better it could be with what the dual-pixel AF tech promises to deliver - seriously, give me better AF and I'd be willing to pay big money for a body this small.

Something else to consider - the 60D/7D sensors have stronger AA filters than the newer 18MP sensors (beginning with the T4i), so the 60D output looks softer at the pixel level compared to the T4i/T5i/SL1/EOS M.  The output from the newer APS-C bodies does not look all that different from the FF cameras as far as pixel level detail in ISO 100 test shots is concerned, have a look:

EOS-M / Re: 2.0.2 firmware and Magic Lantern
« on: July 19, 2013, 12:09:11 PM »
Does ML give the option of putting functionality into the "record" button when not in video mode?

that drives me nuts... i'd love to place back button AF, DOF preview, or something useful there

Same here - it'd be a great location for back button AF.  And a great location for image zoom while chimping - I don't always have two hands available to use the touch screen for zooming around in playback mode, would be great if a button on the camera could swap me through 1x/5x/10x magnification instead of being forced to use the touchscreen.

EOS-M / Re: My EF M 11-22 has arrived

And here some boring test shoots at 3 focals and two apertures:

Developed in DPP, neutral style, noise and sharpening=0, no vignetting or geometrical corrections, DLO data not available anyway by now. 3 focal setting at two apertures, the naming explains it anyway.

I believe the actual feature here is that the lens becomes nearly 2cm more compact when in closed position...

Even extended, it still makes for a significantly smaller package than the EF-S 10-22mm.

So... is it sharp?  In the corners?  At 11mm?  At optimal aperture?

I'd love to know, as I just got my M in the mail today, and a compact UWA for taking landscapes while backpacking would be pretty sweet.

Mini-rant on the M itself: after taking the time to read the right parts of the manual, wow, this thing is actually pretty fun.  Really well built, size so tiny, IQ great for such a tiny camera, and it comes with a nice strap, too.  The 22mm is fairly sharp at f/2, decent bokeh.  AF isn't fast by any means (then again, my other camera is a 5DIII), but once I decoupled AF from the shutter half press (it moves to the "*" button on the back), disabled pre-focus, and enabled the AF+MF mode, it feels right for my walkabout shooting style (shutter release is also quite a bit faster this way).  Would actually make a great camera for street shooting in this setup, assuming you don't mind tweaking focus manually as you go.  For the purposes I intend to use it, I like the M better that the RX100 - mostly because better ISO performance and IQ of the lens the 22mm is way better in the corners than my RX100 was at wide angle.
