Is this the ver I or ver II? I had ver I and altough I liked it, it had a large soft spot in the centre of the frame even at small apertures and softness on the left hand side. I found the lens too wide for landscapes but great for travel and tight spaces as you describe which is the best use for this lens.Size and weight balnce great on the 5D MKII. For landscape the 17-40 would be better since it takes filters easier but this lens is the king of tight spaces.

Maybe its been mentioned already but another disgracfull design flaw that Canon dont admit to is the focus motor/focus color slippage problem on the 70-200 F4 IS. Canon seem to be happy to rip off their customers who are buying into their system and with that comes a certain amount of loyalty to the products. This doesnt seem to hold any water with Canon. >:( Its crazy to think that a customer should pay big bucks to repair a design issue.

Looks like 2014 really will be the Year of the Lens....FOR SIGMA

Really, really important!!! I was regularly texting or emailing photos to my extended family back in Canada each day. They became part of the experience in a good way. It was seamless and instantaneous with the camera/phone integration.

You are absolutely right, there is a massive market for this. Just look at the Nokia Lumia and Samsung models. I have no idea how the three compare to an IQ perspective, but there is going to be a lot more cameras with phones attached than not in the future.

Yeah, consider the size of a 3G/4G dongle, they can be made pretty tiny. They could be integrated into a DSLR with a SIM card slot. Altough you would need to pay for the data.

Lenses / Re: a 50mm dilemma.

Zv is right get the lens that suits you best. Sure the 501.4 A is going to be incredibly sharp but that wont actually help you to take better pictures. However it is heavy and bulky(think 24-70 2.8 size and weight) which may become a factor when you are deciding which lens to take along. I am assuming you are not doing paid work with this 50mm so incredible sharpness should be lowish on the priority list. If you are doing regular paid work with a 50mm then I would consider the Sigma for sure, once it prooves to be a reliable lens AF wise.
The 50L is more compact, still a bit heavy. It is likely to render more nicely than the 50 1.4 A, but that remains to be seen. The 50L is a proven performer and its limitations are already well known so you know them going in.

Lenses / Re: Review: Sigma 150mm f/2.8 EX DG OS HSM Macro

I have had this lens for almost two years and it is a great lens. It has practically replaced my 70-200 F4 IS for alot of purposes. Regarding the lens noise mentioned in the review, the IS on the 70-200 F4 IS makes twice the amount of noise when engaging/disengaging than this lens. Honestly the noises from this Sigma lens are barely audible. This should not be an issue for anyone considering this lens. Also the image floating during IS is much worse on the 70-200 F4 IS. Sharpness wise they are easily equal from F4 onwards but the bokeh on the Canon more contrasty and "special" looking. AF is fast and reliable and I have even used mine for BIF.

I rang Canon at Lake Success and asked them "When the 1D W would be available".
The girl on the phone said she had never heard of it.
Then I said "Ha ha, April fools"
I cant believe they fell for it.

And the difference between, say the 35/1.4 and the older 35/2 is considerable.

I've got one of those 'old' 35/2's, and I love it for its tinyness. That, and the 50mm 1.8 mkI are great little primes that can always find a corner in my bag if I think I might need a prime but don't want the bulk, for instance when I travel :)

True, I currently have the old 35 f2 and am very happy with it and if I bought an upgraded 35 I would definitely keep it as it is a great little lens for size/performance ratio. Likewise if I got an upgraded 50 I would probably keep my Canon 50 1.4 for its size/performance ratio. These lenses have their flaws but the flaws certainly do not get in the way of the photography. I think large lenses sometimes do get in the way of the photography depending on the shooting situation.

Sounds good, I wasn't really expecting this one so soon. With the redesign I hope that they retain the wonderful out of focus rendering that the current Sigma 50 1.4 has because the 35 Art does not have that magic. I also hope they fix the hideous onion bokeh problem. The size is a bit of a concern though as I think alot of people like myself like their primes to be a bit more discreet for everyday/family use. As a professionals choice for a 50 I think it will be good.

I'm a bit puzzled as to why your 70-200mmL f/4 IS has issues at 200mm.  It is much sharper than the 400mm.  Get it fixed, its one of the best lenses for the price.

It s pretty well known the 70-200 f4 IS perfoms poorly when at 200mm and at or close to MFD. I have it and this problem is noticable. Mine also suffers from the dredded slipping focus problem. Buyers beware to check for this issue if buying new or second hand. Sorry for going off topic. Otherwise its a very sharp lens.

I'm with Mt Spokane on this one, and "well-known" to whom?  I owned the 70-200 f4 IS and it was as sharp at 200mm as any other focal length and even with the 1.4x at 280mm, it's sharper than most other lenses.  I think you definitely need to have your lens calibrated/repaired.  Here are some results at 200mm from DxO, LensTip, and Photozone, all showing the lens to be extremely sharp.  Now back to the 400mm 5.6...

The weakness of this very good lens as I stated earlier is at MFD. "Well known to whom"? Google is your friend.

The price difference between a 100-400 II and a Sigma 300 2.8 OS could be as little as $500. I know what I would go for. Of course again neither exist so...

Third Party Manufacturers / Re: Off Brand: Nikon Announces the Df
« on: November 06, 2013, 10:45:39 AM »
I would buy a Canon retro style or mirrorless only if it was smaller, lighter and took EF lenses without an adapter(adapters just add bulk).

Taking EF lenses without an adapter means maintaining a 44mm flange focal distance - so you can kiss one dimension of 'smaller' goodbye, which is why I doub't we'll see such a camera.   

OTOH, you've just descirbed the SL1, except it's neither mirrorless nor retro.  ;)

Thanks I knew there some constraint like that. Actually I think the RX1/r still still the best size.weight/image quality solution as a second "go anywhere" camera. But who is going to spend 3300Eur on a second camera? Such a pity about the price but it might drop when the A7 is available.

If Canon were ever going to release a retro, now would be a great time and undercut the Df by few hundred. No one can deny that there is a market for these retro style cameras. I'm sure the Canon accountants are hearing ching ching sounds looking at all the hype that has been generated recently with smaller/lighter/retro offerings. This camera has made all the headlines in the last week or two. And Fuji are doing great with their line of retro cams. I see them more as a second camera, a smaller lighter option when you dont want to carry around the big black DSLR. Stick one lens on it and you are out for the day. This is were the Df fails miserably. Its as big as any full frame DSLR and as expensive so why bother? It doesnt provide enough differenciation from a modern DSLR. I would buy a Canon retro style or mirrorless only if it was smaller, lighter and took EF lenses without an adapter(adapters just add bulk).

As always with a new lens (especially from a third party manufacturer), people state that that they will be happy to consider it as long as it is:

  • "Very sharp" -often stated as "sharper than (some optically flawed lens)", "as sharp as (inset name of Canon 'L' class lens)"
  • Fast aperture
  • Lightweight
  • Cheap -often stated in similar terms to the "sharp" criterion

What a shame that no manufacturer has yet managed to rise to the challenge of meeting these conflicting objectives.

Whilst I'm at it, I'm looking for a car that's small, economical to run, can do 0-60mph in under seven seconds, can carry six adults with luggage and costs no more than a family hatchback. Come on Ford, surely it can't be that difficult?

I think Sigma is rising to that challenge of those conflicting objectives. 35 1.4, 120-300 etc.
The telephoto community is holding its breath for alot of lenses at the moment i.e. Canon 100-400II, 400 5.6 IS, Sigam tele primes 300 2.8 or 400 f4. And thats why alot of people will not give this lens a second thought even if it is a decent performer.
