Haven't people been whinging out Canon not making dedicated prime lenses for APS-c ? Now one has been produced they are claiming it should have been FF ?  ::)
I am one of those who lived whining by the lack of primes EF-S. ;)

One detail prevented me from popping champagne joy... ??? The F2.8 aperture at 24mm, could already be covered by a zoom. :-\

Maybe I'll buy an EF-S 24mm, but I'd be singing praises for Canon, had it been an EF-S with maximum aperture F2, F1.8 or even the size, weight and price were doubled. ::)

My understanding of the pancake design is that they are pretty much an unmodified planar, and therefore (relatively) slow. But on the subject of 2.8 being accessible with a zoom, I do find that what makes even a relatively large dslr like the 5D 'big' and 'heavy' is the unsatisfactory balance that larger zoom lenses give the body when carrying around. So for me these 2.8 prime lenses do have a use. Maybe not this new 24/2.8 because I shoot FF. Pitty it wasn't in an EF  mount  ;)

If I was a crop shooter I'd be very pleased with this offering. 38 -40 mm FF equivalent is a great all purpose focal length.

Anybody else noticed on the 1Dx Gallery you can no longer post images ??, make comment etc ?? Or is this issue particular to me ??

1Dx & Otus 55f/1.4 @ f/4 1/60th ISO 100

Naoshima Island Japan

What an unusual picture !

And just shouts quality. I've always been a fan of 50 mil on 35 mm format, looks like the Otus and Sigma will rekindle interest in that focal length, a good thing.

The lens looks very good across the frame, but quite honestly I found the smoothness and tonal graduation from the 7DII really impressive !

The digital picture ISO crop comparisons between asp and ff are one sure way of putting someone off buying a crop camera.

Ugh? Why would I want to do a thing like that? I'm an outspoken fan of crop cameras for macro and general low iso shooting and like my snappy 60d over my 6d. But there are some lenses that gain by being put on crop (cutting off blurry corners), and some loose (lack of sharpness wide open), and some have both effects at the same time.

Here's a link to 60D with Zeiss Otus and 1D with Canon 50 f1.4

Fair enough, so let me re-phrase it: The tdp comparison of the 70-300L happens to show - for whatever reason - about what I see from my copy of the lens on my 60d and my 6d. Which brings us to the all-popular "wrong afma, broken lens, bad handling" theme, but I don't think so in this case.

This was about a different point anyway: If the op is fine with the 70-300L on his crop, I don't think there is a need to look at the very best and most expensive lenses for him.

Using Photozone as a reference it looks to me as if the 70-300L cannot quite fully resolve 15 mp on APS-c when wide open at 70 mm, let alone 18, but the OP never said he was using this lens wide open. I disagree with your last sentence because the 'very best' in resolution terms doesn't have to be 'the most expensive'. These high mp asp-c cameras need really good lenses, and Canon now provide ones that are up to the job without being expensive; look at the 40/2.8 and the new EF-s 24/2.8.

Those Digital Picture A/B Comparisons always leave me lusting after a 6D. But when I download the RAW examples over at DPReview, I don't see quite as drastic a difference.

I have the 15-85 on my 60D - and stopped down to F8 for landscapes it's hard to find anything better at the wide end of it's range. To get any real improvement from there, I'd think the sensor would be the upgrade path.

I missed the sarcasm tag off my previous post. I think TDP crops between asp and FF are misleading, and probably shouldn't be compared against each other, in the same way as imatest results shouldn't be compared across formats.

That might be true in your case, but it doesn't mean it is universally true. Nailing every one of those 18 mp on your 60D with a 70-300 takes some doing. With really sound technique the only difference will be the amount of post shot magnification required.

I shot about 100k frames with my 70-300L on my 60d, so I guess some of them were in focus and without shake or motion blur, even if only by pure chance. And at least with my copy there's a distinct difference between f4 on crop vs. ff - that's why I mostly stepped down to f5.6 on the 60d. Here's exactly what I see:

If it is true that production of this lens has been put on indefinite hold then it fits well with the comments that many of us here on CR made when the rumour of its imminent existence was first reported.

If they thought the time was right for them to meet the major dslr manufacturers 'run of the mill zoom lenses' head on with a more expensive but similarly performing product they were wrong.

ajfotofilmagem - 'Wow' as in image quality/sharpness. That's what I particularly noticed in using the 70-300L and the 50mm over the 18-135.

In that case, your personal "wow" is cheap to come by: The 70-300L is certainly a good lens and very sturdy, but on crop wide open it's noticeably less sharp than on full frame. So any half-decent midrange lenses should satisfy your needs.

seems like a new kind of spam

?

I linked this fellows work on 500 px a few months ago when we were having vitriolic arguments about Exmor's ability to produce quality pictures whilst Canon can't. (Sarcasm alert !)

(They are actually composites, but great images, so who cares).

Canon General / Re: Does Canon really deserve this?

A Fujifilm XT-1 if I remember. A really neat little camera that has so much going for it - except it's not a FF 6D, with a crisp OVF.

Do I detect a hint of jealousy there?

 ;D  No. I have always liked Fuji, right from my days as a teenager using an old Fujica ST701, and I think the XT-1 system is quite appealing. But; I don't feel that the slimmer body is worth trading the OVF for, or losing the full frame. And, as has been pointed out here on CR many times, to achieve the equivalent in lens speed on these crop systems is actually very expensive, more so than FF. Add these factors to the reduced versatility and no, the system isn't for me.

Dearest friend, have you personally ever tried EVF?

Yes, of course, the XT-1 which I understand is probably the best out there at the moment. I thought in my previous post I had made it clear that I have considered the Fuji system.

What can I say ? Call be 'old fashioned' but I like to be able to optically see through the lens in real time, at least on a decent system. I don't think I am alone in this.  I can see that EVFs like the one on the Fuji have great appeal to many; indeed most people are going to find it better than a dim, small pentamirror with slow 'kit' lens on a Rebel, but even then people keep buying cheap dslrs, probably because as it is a mature, simple system it is also cheap to produce and buy.

I perceived a lag, maybe that is just my imagination. The very large size doesn't do it for me, but the ability to reduce the viewfinder size is neat. Then there is the power useage; I want a battery to last as long as possible. In fact I have recently ditched by iphone and got a simple Nokia with a keypad because I am sick of having to charge the iphone every day. Just been to Poland for four days; never had to charge the phone or the camera !

I think we are going to see a FF dslr from Canon which will have interchangeable finders, like in the old days of top end slrs, except now one will be a normal pentaprism, and will be used in the conventional way, and another will be an EVF. You then lock the mirror up and away you go, using the Dual Pixel AF system direct off the sensor for focus. Use it for stills or video, it's up to you. By having the head as a sliding fit from the rear it could incorporate physical plug connections, which would probably needed to do this.

Then those that say Canon isn't innovative will have to find some other area to whinge about.

Thanks so much for replying. I personally find the advantages of EVF overpowering the disadvantages in such a carry around camera. But want my optical on the 1dx.

I tend to agree with you. If manufacturers can bring EVF of the XT-1 down to the prices of a simple, pentamirror system few are going to buy the latter, whereas a high quality, large pentaprism OVF still offers a great deal on larger, more general purpose cameras. However OVF manufacturers could retaliate by giving the lower end cameras a decent pentaprism system and good magnification like the 7DII. I could see someone like Pentax and Canon doing this.

Personally I do not like two systems; I want one 'do it all' system that is light enough for casual travel and good enough for professional work.

This is possibly to do with the fact that skinflint Sporgon likes to spend his hard earned cash on fast horses and fast women, not necessarily in that order, and not photographic gear  ;)

The trouble with focal lengths of 10 mm etc is that they are only passing a tiny amount of light for a given exposure. One of the reasons you have a 'wow' factor on your 70-300L lens is that apart from it being a very good optic you have huge magnification and light compared with a much shorter focal length.

So if you want the same 'wow' factor from a much shorter optic on APS, my advice is don't go too short, put funds into a better computer / software system if necessary and stitch. The 24 mm on APS is an ideal focal length when shooting the picture in portrait orientated sections. The 24 mm in portrait is giving you the vertical field of view of a 16 mm lens in landscape orientation, but you are using twice the volume of light to make each section of your image than you would if using a 16 mm focal length.

The new EFs 24 mm f2.8 pancake. If you want to go wider for landscape, stitch.
