EOS Bodies / Re: Another 50mp FF DSLR Mention [CR2]
« on: Today at 08:45:43 AM »
While I would have loved to have 30, 40 or 50 Canon megapixels a few years ago, I'm not sure the L lenses available in 2008-ish could adequately or comfortably resolve that much detail.

I suspect Canon is pursuing a reasonable strategy of --

1. get the lenses capable of resolving 50+ mp first,

2. then release cameras with sensors that can deliver them.
Canon has already updated most of the L-zoom range in preparation for higher megapixels. With the 100-400mm already officially on the, we now only await the ultrawide f/2.8 zoom update. Zooms are more versatile and cater to a bigger market than primes so get priority for R&D.

Anyway, there is no need to worry. There are already many lenses in the Canon Lineup that can resolve more than 30MP and not all of them are expensive. As an example , the cheapest lens in the Canon range, the 50mm f/1.8 can resolve close to 40MP when shooting at f/5.6. The 40mm Pancake is another good performer on a tight budget. Top-of-the-line lenses like the 300mm f/2.8 and the 600mm f/4 could deliver around 50MP of detail given a 54MP sensor.

This is not simply me pull numbers out my ass, it is based on a work in progress. I won't go into my methodology, but you could get an idea of which lenses are good for high res by looking at APS-C crops at TheDigitalPicture website. The 60D is an 18MP body, which when extrapolated to full frame is 46MP. Lenses with good corner performance on full frame hold up to the the APS-C crops. Lenses with bad Chromatic Aberration and soft corners on full frame are not "future proof" and will likely be replaced in the next couple of years.

That sounds like a good objective assessment of the practical issues. I'm expecting the remaining older L prime lenses (the 35 & 50) to be updated soon. It also tallies with word from a professional photographer that there is a high megapixel camera in the wild being tested, but will not be released until the full range of lenses is ready for it. I'm also hoping for replacements to the non-L 20mm and 50mm lenses amongst others. But as noted, zooms are the bigger market, and what I would choose if I had to shoot professionally under pressure.

A high 50MP sensor would give scope for a crop mode, as found on Nikon cameras. A 1.4x crop would give a 25MP image, and a 2x crop would give a 12MP image. That would be a great way to give extra reach to my 70-300L

What is bound to disappoint is the frame rate on a 50MP camera. There will be just too much data for the electronic bus to allow the 10 frames per second of the 7D2. Yet again, not everyone will be happy! Though in the next few years card and processor speeds will increase to alleviate that limitation of current electronics.

My copy was delivered by the big brown truck last night. I'm looking forward to playing around with it over the long holiday weekend.

And after that I like the idea of just leaving it on an old Rebel as a "compact, no excuses to bring with, take anywhere" camera.

Update us on your impressions when you get the chance if you don't mind. Thinking of buying one of these as a gift for a friend with an SL1. Hoping she'll stop borrowing my 24 2.8 IS  ;)

I think that he/she will borrow it less often. The colours appear as great on the STM as the IS lens, from this initial impression. However, IS is addictive for a walkaround lens.

Hey, who's side are you on here? Hopefully she'll find the smaller size more appealing than the IS. ;)

Here's hoping! Good Luck  :D
The problem with reading this site is that I keep wanting to add to my kit

Hope that helps!

Yes it does. Greatly. A new world of discovery (and spending) awaits. I think that a 320EX or 430EX may come ahead of the MR-14EX. Where the ring may excel is on a construction site where it may not always be practical to place a flash off camera.

When I returned to SLR photography, I thought no film, no processing, I just need to buy the camera and I have a free hobby ...

I like my MR-14EX and I enjoy my images I get with it.

A feature I often use is changing the flash power between the left and right tubes, which does give dimension to the lighting.

I shoot with a 100mm L macro and often in combination with extension tubes.

I'm not a flash fundi and I'm sure you may get different answers to mine but I do enjoy the results from my ringflash.

That's great to hear, it sounds like I would get full benefit only when I have both the 100 macro and ring flash. maybe I should bring that day closer by going without the red ring and IS, and putting the saving into the MR-14.

I have a 50 macro, and I'm planning to buy a 100L as soon as funds allow. Should I be tempted by this as both a macro flash, and also for use as a standard (albeit low powered) flash to save me buying another?

NO. It is no substitute for a more versatile flash, indeed I have always found it much easier to make big and powerful smaller and less powerful than the other way around.

It looks like both may be in my future....

GN = 14.  As a regular flash, a 270EX II is more powerful and can be bounced. 

What sort of macro do you shoot?  The MR-14 provides rather flat lighting.  It's great for documentary shooting, medical images, etc., not as good for creative stuff.

My typical photography is architecture, interiors, close up details (probably not quite macro, but closer than a 50/1.4 could go). I tend to not like adding light, because one of the things I am recording is the design by the architect, interior designer and lighting designer. There are however times when extra light, or more even light, would be beneficial for a close up. Full macro will come with the 100L sometime in 2015.

The second time I might find flash beneficial is at the monthly computer group where I take the event photos. This is held in a nightclub, with the expected high contrast lighting design. We also have a projector running, so the beam complicates things further. On its own, the 6D copes well providing I stick to manual settings of ISo 6400 / Aperture f/2.8 and shutter 1/30, giving the light meter no opportunity to be confused by point sources of. Typically I would only need a flash to illuminate to a distance of 5-10m/15-30ft, probably never more than 15m/45ft. This would be at ISO 6400, not 100, so I don't know if a 14m range at ISO 100 would give the range. Obviously a 270EX/430EX/420EX would be more effective, but would not cover the close up and macro.

I may ultimately end up buying both as I progressively build my kit, but it would be great if a macro flash could also cover for portrait distances. That is probably what I will buy first for the close up work, but if it can cover for both it will become a bigger spending priority over lenses and other tech.

My history with OM-10 and 6D has not involved flash so far, so I'm a total newbie to the subject (apart from the built in flashes on compact cameras and phones).

Lenses / Re: Landscape Lens for Crop To Make Me Go Wow!
« on: November 26, 2014, 03:05:44 AM »
I have a 70-300L too and know what you mean, though my 24 IS comes close. The 16-35/4L reviews well, I'm tempted as a more versatile alternative to the 24, and suspect that you would be wowed by it too.

I have a colleague with a Sigma 10-20 on his Nikon, he likes it enough to keep it on the camera.

If you are looking for landscape, the options open up considerably with full frame, and the entry price drops every year. Maybe 16-35/4L for the 650D now, and consider adding a full frame body down the line. The 70-300L is excellent on a 6D, though it wouldn't have the reach you are used to on the 650D.

If this can be done with a 1.6x crop sensor, then the next generation of full frame cameras with 2.5x the  sensor area should mute the critics, at least for a short while.

Fat chance.  ;)

Great review...
Pretty much comfirms to me this camera is far from being a dud, but a camera I believe will help me deliver the goods.
It would have been unrealistic of me to expect 1Dx performance at a greatly reduced price just because it has a couple of FPS fewer and a cropped sensor. Sure, it would have been nice to have a sensor with much higher DR and less high ISO noise but the truth is I rarely shoot action in low light situations and as suggested by Bryan, I can always use my FF 5D for those darker moments ( I can't justify a 1Dx for my work).  The sensor which seems to attract alot of criticism is just but one component (albeit important one)in a camera but for me, the AF, FPS, durability and available lens system is just as important.

I have total faith in the Canon lens system and looking at the Canon body line up, the 5D3 is too slow and the 1DX is too pricey. It looks like I only have one to choose from. The product people at Canon have certainly got me in their  buyer pool!

Yeah, I tend to agree with Bryan that the IQ is far better than the 7D's and quite a bit better than the 70D's.  Combined with a superb AF system and amazing performance, it looks like a huge winner to me.  So many reviews are talking about how well it does at high ISO, which also gels.  The constant negativity about it seems surprising...yet I guess I shouldn't BE surprised at it ultimately! LOL  :o

If this can be done with a 1.6x crop sensor, then the next generation of full frame cameras with 2.5x the  sensor area should mute the critics, at least for a short while.

You have asked this twice! I have answered the other, coincidentally I had suggested the 18-135 though you hadn't mentioned it there.
