Lenses / Re: Sigma 50mm Art 1.4 Focusing problems

But it's annoying to buy a fairly expensive AF lens which you're expected to fiddle around with on a docking station and even then seems best used, in the case of many copies at any rate, in MF mode.
...

Why do you think AFMA exists on Canon cameras? To address the same problem that the docking station is for.

The problem isn't QC it is engineering tolerances and the fact that neither camera nor lens are all made the same. There is copy variation between each camera and lens. This means that whilst AFMA might be +5 for a given lens on your camera, that same lens might be -5 on my camera and that same lens might be +0 on someone else's camera.

I don't disagree with any of that (to the extent you're talking about AFMA adjustments rather than inconsistency).  My comment wasn't specifically about Sigma, though it seems more of their lenses need adjusting than others and more of them focus inconsistently within any given AFMA tweak.  But after using a variety of mirrorless cameras over the past 18 months, where AFMA simply isn't an issue, I'm getting less tolerant of/patient with this aspect of dslr technology.  As for inconsistency within any given AFMA adjustment, presumably mirrorless isn't helpful, but manual focusing avoids that and mirrorless cameras make manual focusing easy (I recently bought an EF-mount version of the excellent Sigma 70mm macro and have been using it on my A7r rather than my 5DIII - so no focusing problems at all aside from incompetence at my end...).

Third Party Manufacturers / Re: Anyone own both Canon and Nikon

Sure, most pp software provides lens correction, but not on off-brand combinations.. so you will not get the proper corrections on something like the 14-24mm when used on the Sony body as you would on a Nikon body, and the same goes for the 17mm or 24mm TS on the Sony body, but the Canon's would need less correction to begin with.


I don't think you're right about off-brand combinations.  In LR, I can use a profile for any lens I attach to my Sony A7r & a6000 (provided they have one for that lens in the first place, of course); with my Canon lenses, the corrections seem to work exactly the same way regardless of whether they're on my Sony or Canon bodies.  The only difference is that with off-brand lenses you have to take an additional step and manually select the lens - you can't just check a box and have the corrections applied automatically.

As for Nikon, do their dslr in-camera corrections apply to RAW files as well to jpegs?  That seems to be the case with m43 cameras (at least when using LR), but is it true of Nikon dslrs too?

Lenses / Re: Year of the lens....a joke....?

The 16-35L IS and the 10-18mm IS alone make this year great for Canon users. If they add the 100-400LII, it would be the year of the lens.

Exactly - those two excellent wide zooms aren't bad for half a year.

Just got my RMA from B&H.  Simply don't want to deal with the dock.  Also, just read on the lensrental site that they have had "multiple" problems with the lens locking up during adjustment on the dock.

And I don't play the "good copy" game.

Lovely bokeh, all around IQ, but I'm too spoiled by AF to give it up for MF!   :-X

I expect that if I ever decide I want this lens I'll buy an EF mount but use it on my Sony A7r, where MF is easy. But it's annoying to buy a fairly expensive AF lens which you're expected to fiddle around with on a docking station and even then seems best used, in the case of many copies at any rate, in MF mode.  (Speaking of MF, I've recently been greatly enjoying a 50mm 1.4 Pentax/Takumar; excellent image quality, small, fairly light and, to these eyes, more attractive... and it just works.  All for c. $100.)

Thanks for doing so!

EOS-M / Re: How Much Would You Pay...
« on: July 15, 2014, 03:04:04 PM »
For $1.5K you can buy a Sony A7, which will give you much the same high ISO performance you're asking for (you're not going to get it via current technology on APS-C).  For <$600 you can buy a Sony a6000, which may be as good as the 70D in terms of your AF requirements (I don't know first hand as I don't shoot fast moving subjects and have never used a 70D, but reviewers seem impressed by the a6000's AF) and has better image quality than an M (good though that is).  As far as APS-C and FF mirrorless bodies are concerned, those (and the other two A7 bodies) are what Canon would need to match or surpass (IBIS would be nice) as far as I'm concerned.  If Canon did such a thing - I guess it's not impossible - I would pay at least those prices; but I wouldn't pay a penny if it/they didn't/don't have a built-in EVF.

Two questions:

What can Canon put into a T6i to make it interesting?

What can another brand put into theirs to make Canon envious?

At the moment I can't think of anything to answer either of those questions.  Anyone?

Jim

Making it interesting to those who read this forum and making it something that consumers are going to want to buy are probably rather different things.  I have no clue about the latter.  To interest me it would have to be something like the Sony a6000 but with IBIS added, and that surely won't happen.  As for Canon being envious, they may be noticing the slight uptick in mirrorless sales in recent months, but otherwise they seem to be doing rather well as it is (even if some might think they don't deserve to).

As you say, old MF lenses provide a cheap, engaging adventure, often with superb results too.

I like the way you put it, and it's so true. I picked up a Sigma FDn 70-210mm 3.5-4.5 APO the other day that gives stunning results on my NEX, both with a Metabones Speed Booster and without. It's strange to say, and unexpected for a Sigma, but optically that lens is in 'L' territory. Maybe that's why it (deservedly) carries a red stripe.

Thanks for the tip!  So far my dabbling in old MF lenses has been limited to primes, so that might be fun to try.

Tourists are on holiday, not a photography shoot. Let them enjoy their holidays and their snapshots. Life is complicated enough as it is.


Yes, of course; to that extent you and acutancephotography are right - A-mode is just fine (but then if snapshots are the criterion, one has to wonder why they're using a dslr of any sort in the first place...).  What amuses/interests me is the implicit assumption that tourist photography is just about replicating postcards and providing photos of husbands/wives posing awkwardly in front of monuments - or is that simply what the term has come to mean (just as "soccer mom" has somehow come, rather insultingly, in the US to be the archetype of a certain sort of clueless/lazy/uninterested photographer)?  Maybe that's Dylan777's point.

Regardless of that, is it really still the case that in A mode you can't select focus points? That would drive me nuts.  (The only camera I have with me is a Sony a6000, but as the lens attached to it is an elderly Pentax-M I can't use the camera in either of its two "intelligent auto" modes to find out first-hand.)

I know I want 4.0 for the weight savings, and non-IS version is not an option. Is the 2.8 really that much better if I don't need 2.8 aperture?


As everyone else has been saying, no, not much better (probably not better at all unless you do side-by-side comparisons at 100%), unless you need the extra speed.  For that matter, one could say much the same thing of the 70-300L (where the extra focal length makes up for differences in aperture with regard to depth of focus - plus, it has very smooth bokeh).

Personally, I would love a vastly improved/full frame version of the M but not sure if Canon will have something substantial out before the competition.


I would love that too, but it's beyond any doubt that the competition, such as it is, is already way ahead of them (esp Sony A7/a7r/A7s & A6000, or, if you don't mind the smaller sensors, the better M43 cameras)!

I like my GAS - it pushes creativity too; especially when it comes to old MF lenses that I adapt to my NEX body. In fact that part of my GAS is quite easy to afford.... and thankfully it keeps me from buying more L lenses.

I quite agree.  I'm lucky enough not to be a professional photographer and thus to the extent I have "needs" and "essentials" they're merely want-driven and thus arguably not really needs at all.  As you say, old MF lenses provide a cheap, engaging adventure, often with superb results too.

If I hadn't started using mirrorless cameras 18 months ago, it would have been rather easy:

6D or 5DIII w 16-35mm f4 + 70-300L + 100mm L + a fast 50mm (Sigma Art, I guess).

That said, if stayed with dslrs and really had to cut back, I could do quite well with merely:

SL1 + Canon 10-18 + the latest Sigma 18-250 macro - a surprisingly good combination that together costs less than just about any L lens by itself

But the more I use mirrorless bodies the more dslrs feel obsolete to me (I was using my 5DIII outside for the first time in ages yesterday and, aside from being far less useful, it felt like so much pointless ballast).  But I'll keep one, if only so I can easily use my 70-300L.

Otherwise, until Canon comes up with a decent mirrorless camera I would pick:

Sony A7r w Sony/Zeiss 55 1.8 (much of the time I could probably stop right there) + a wide zoom (the impending Sony perhaps, or the Canon 16-35 f4, so I can use the lens on the 6D/5DIII) + Canon 100L + a few favorite cheap vintage fast primes (which oddly seem far less obsolete to me than dslrs)

or even, if I wanted to minimize weight/bulk

Olympus OM-D w a few Olympus & MF fast primes + Panasonic 100-300

Consider that across the Internet, criticism of DxO typically only comes from people that own Canon products. That piece of data speaks volumes about how DxO results are absorbed, don't you think?

I'm not sure what "typically only" means (do you mean "usually" or "most of the criticism I've seen" or "most of the criticism I've noticed"?) but I often see criticism of DxO on forums (esp. m43), including at DxO itself.  Perhaps that "piece of data" speaks volumes too.

I think we have a winner. This should be considered as the "BEST" reply on CR in 2014.....LOL ;D

Yes, no contest. 

I wonder if Jglaser writes similar things when he changes brands of laundry detergent.

In what ways do you think it's not as good as the 10-22, aside from the obvious differences in focal length and max. aperture?  (I'm impressed by the 10-18 but have never used the 10-22.)
