Third Party Manufacturers / Upcoming Sigma "trifocal" lens?
« on: March 03, 2015, 10:00:46 PM »
Sigma is hinting at upcoming "unique" lens, risky and odd like their 18-35 f/1.8. 

Sigma Rumors is thinking it may be a trifocal lens. http://sigma-rumors.com/2015/03/sigma-upcoming-very-unique-lens-thoughts/

I guess the idea is it could be optically simpler and would not have to be good at every FL, just the 3 of them?

Lenses / Re: APS-C 60mm or 100mm macro lens?

A macro lens is one I would seriously consider buying pre-owned because so many seem to get very little use before they are unloaded.  It seems like every one I see on Craigslist is a case of "I really thought I would use this thing, but I shot it 4 times then put it away for 3 years....".

EOS Bodies / Re: EOS 6D II - what's inside?

How about a flash sync speed above 1/180th?  A simple standard 1/250th would be nice, but if Canon could find a way to get faster without HSS it would be a nice selling point on all Canon cameras.

Other peoples photos of Holi festivals are great but I would not take my gear anywhere near one. Among others, Roger at Lens Rentals has written of the toll that colorful powder takes on cameras and lenses. It gets absolutely everywhere.  Roger imposed a NO HOLI SHOOTING policy with his rental equipment.

EOS Bodies / Any way 5d3 goes UP when 5d4 announced?
« on: February 27, 2015, 07:33:06 AM »
Looking at the great prices on 5d3 right now ($1950.00) and tempted but not knowing what the 5d4 specs will be I hate to pull the trigger. 

I have seen claims that old lenses occasionally go up when a Mk 2 comes out, though I have not actually seen it happen myself.  Any chance of that with a body?

Do you think these grey market deals will continue after 5d3? 

Do you think they will continue selling 5d3 for a while alongside 5d4 (and 5ds and 5dr) or will they discontinue it almost immediately?

Customs problems?

No. Docks and all the stuff being held hostage.

The zoom is clearly a lens for a compact camera or such, the 50mm f1.3 could well be the fabled 50mm f1.4 and labeled as such

Maybe but I think if it was f/1.3 they would call it that and not rob themselves of the credit or the bragging/marketing value of being brighter than the competition. ;)

Either way I agree they should have led with that rumor as the subject!

Third Party Manufacturers / Re: Sigma 85mm f/1.4 Art Lens Next? [CR2]
« on: February 17, 2015, 01:50:36 PM »
Sigma already makes a very good 85 f/1.4 lens. The sales volume of a 85 f/1.4 Art lens might be greater than for a 135 f/1.8 or f/2 lens, but is that difference more than the difference between sales of a 85mm Art lens and the current 85mm lens? Or are potential buyers for the current 85mm lens deciding instead to wait for the 85mm Art lens?

Well, it matters to me.  I have zero interest in the old Sigma 85, and I would very seriously consider getting an 85mm ART, having enjoyed my 35mm ART so much.

Maybe it is unjustified but "old" Sigma has a Stigma (pun intended) for AF issues, reliability.  The ART line has been winning awards for sharpness and they look and feel great, and are at very least psychologically a break from the past.

EOS Bodies - For Stills / Re: Monopod - advice what to purchase
« on: February 07, 2015, 01:11:39 AM »
You don't need a ball head on a monopod like you need one on a tripod.  You can tilt the whole thing as you like.  They have arca Swiss compatible clips you can put on the monopod and you keep he arca plate on the camera.

EOS Bodies / Re: Bingo! New Canon 5Ds has 50.6 MP new rumored specs
« on: February 04, 2015, 08:26:17 PM »
So I found this to make things interesting.  James Miller is a cinema/video guy in the UK who now works some with Philip Bloom.  Apparently Miller tore down his 5D3 a couple years back and ditched the AA filter.  Here's what he got:

http://www.eoshd.com/2012/03/james-miller-removes-optical-low-pass-filter-from-5d-mark-iii-for-resolution-increase/

Obviously more detail without AA, but I can damn sure see the aliasing particularly in fine edges of pavement stripes and in the parked cars.  Does the added detail (false, noise, real, otherwise) outweigh the use of the AA.  Miller seems to think Canon "used too strong an AA" to begin with.

That said... This is a 22MP sensor.  Now with an almost 250% increase in density... is aliasing really going to even be a factor?  Using his own pictures and video in Brighton Beach, how much of that effect can we assume 50MP would mitigate on its own without the filter?

If medium format 50MP cameras are without an AA, could this body (the R) not also stand up the same way (granted there's an obvious sensor and pixel size difference)

Toss out your thoughts please!  This would be a lot more interesting than pop-up flashes.... geez... come on guys!!   ::)

I agree this is more interesting than pop up flash, .......so........... I BUMP THEE.

Lenses / Re: A New Nifty Fifty Coming [CR1]
« on: February 04, 2015, 08:20:22 PM »
I gave up waiting on a good 50mm and bought a 35mm on full frame.  Glad I did, as I find the 35mm to be a great length.  Now, however, I would be hard pressed to justify purchasing an expensive 50mm because it is so close to the 35mm length.

I WOULD however buy a new 50mm f/1.8 to play with if it were only about $200, if it had improved IQ at f/1.8 and a more solid body, better focusing than the old nifty fifty. 

And if IQ  wide open was better than the f/1.4, I could easily give up the tiny tiny, less than 1/3 of a stop loss in aperture of 1.8 vs. 1.4.

But posters above are probably right and this will be an M lens.

Nice shots.

The 18-35 f/1.8 is so cool it is hard to get excited about the 17-50 2.8 lens. 

You have a 50mm prime for when you need 50 mm.

I would do the 18-35 1.8.  With a crop sensor you cant use ISO's as high as on full frame with as good an image quality.  The wider 1.8 aperture buys you an entire stop of light you can use to get decent shutter speed wih tout having to use the higher ISO and the IQ penalties that come with it. 

And at wide focal lengths like 18-35 you keep a pretty thick depth of field, so it is much more practical to work with than a more razor-thin DOF you'd get on a 50 or 85mm lens wide open at f/1.8.
