Lenses / What would a 16mm or 18mm F2 FF lens look like?
« on: July 22, 2014, 02:55:21 PM »
Wider than the Canon 24 F1.4L, there are no lenses in the lineup faster than F2.8. Do others think there would be a market for a 16mm F2L or 18mm F2L prime lens? It would be a stop faster than a 16-35/2.8 which would be awesome for indoors shooting, night sky photography, photojournalism, etc. Would a lens as wide as 16 or 18mm at F2 be able to retain a 72mm or 77mm filter size?

Lenses / Will Sigma 50/1.4 Art push Canon to release a 50/1.2L II?
« on: April 21, 2014, 02:17:55 AM »
The Canon 50mm F1.2L certainly can produce a beautiful photo, and has wonderful bokeh, but there are still many complaints that users have regarding softness wide open, focus shift, and major AF shortcomings. This lens was released 8 years ago. Do folks think that Sigma's production of their 50 F1.4 art will put pressure on Canon to release a higher-performing 50 F1.2L II to outcompete it? If the Sigma ends up performing as well as anticipated, at its price I would think many 50L users might jump ship. Curious to hear folks' thoughts on this...

EOS Bodies / Dual-pixel AF and ISO performance?
« on: November 23, 2013, 05:10:40 PM »
I switched from Nikon to Canon recently, and for my crop body went from a D7100 to a 7D. The 7D seems great with the major exception of high ISO performance, which I find disappointing compared to the D7100. Yes of course the D7100 is much newer sensor technology, so it should be better at high ISO, but I have high hopes of a 7d mk II in 2014 that would trump the D7100 at high ISO because of even newer sensor tech.

But now with the 70D having dual pixel AF, which is of little use to me since I don't shoot video, I assume this will be in the 7d mk II as well. My question is: Does dual pixel AF have the downside of hindering high ISO performance? I have read this from uninformed sources and am curious if there is truth to it. As a still shooter, I would be way bummed if technology that mostly benefits video shooters was really hurting us still shooters! I want the best high ISO performance possible in a crop body for stills and would be thrilled to see a 2 stop improvement over the current 7D, but man what a bummer if we saw only minor improvement as a result of dual-pixel tech implementation. (would be WAY cool if Canon offered 2 versions, a video optimized version and a sills optimized version). And before you tell me to just go full frame if I want quality high ISO, I own a 5d mk III and love its high ISO, but will always switch to the crop when I am shooting wildlife or other reach-limited scenarios.

Thanks for any clarification on this dual-pixel AF tech question!

Lenses / 135 F1.8L IS
« on: October 28, 2013, 02:25:26 AM »
Who else would be all over this if they could keep it to around 25% larger than the current 135L and 50% more expensive ($1,700 range I'm thinking). The current 135L is really nice but lacking IS and weather sealing are bummers, and the extra 1/3 of a stop with F1.8 would be appreciated for really low light work like concerts. I know it has been patented and the current L lens is a pretty old design - would be sweet if Canon brought this patent to market in 2014. Yes yes I know it will be a good bit more expensive and also larger than the current lens but I think the upgrades would be well worth it. I'm curious how many other folks feel the same way. What a sweet pairing it would make with the 70-200 F4 IS or 70-300L to cover the normal telephoto range.

EOS Bodies / 7DmkII F8 AF for wildlife?
« on: September 30, 2013, 05:09:16 PM »
I am getting more serious about wildlife photography and recently switched camps from Nikon to Canon. Loving the Canon glass I have been shooting. One thing though for budget wildlife photography that Nikon currently has going for it is the D7100's "reach" between being able to AF with teleconverters at F8 (for example the 80-400 + 1.4TC) as well as the 24mp pixel density.

Do others think Canon will try to keep up paces and add F8 AF abilities in the 7DmkII, like implemented in the 5DmkIII, to keep up paces with the D7100? The 400mm F5.6L + 1.4TC on a 24ish megapixel crop sensor would be a budget/travel wildlife photographer's dream! At least for me. Curious if others think the demand is there for this AF implementation to make it to crop sensors in Canon land.
