Lenses / Re: Tamron 150-600mm AF servo issues?
« on: March 27, 2014, 08:32:44 PM »
There has been a major delay in getting the lens here in Australia, in that an order I made in early February has been delayed to April.  Everything Ive read indicates there was an issue, and some level of correction has been carried out, which has caused the supply delays.  As stated, they seem to be only with some bodies, but the 7D would be a pretty popular camera for this lens, so it will be important to fix it.

Latest update is that it might be here next week, so will be able to check for myself, have a 6D and 7D.

And you have hit the nail on the head.... You can take any current DSLR...Nikon, Sony, Canon, whatever.... And take wonderful pictures... The differences are minimal to the average user.

This gets brought up in these discussions regularly, but it's not really saying anything at all, is it?

Every camera  technological debate thread can end with "all cameras take nice pictures".   

But a site such as this operates within a tech-context, and tech thrives on incremental improvement. So saying "the difference is minimal" over an over in every thread along with other platitudes dilutes the discussion.

The particular tech matters though, particularly when advising on buying options to  comparatively uninformed people - HiFi is dead to most people as an important thing to argue over, while CPU or videocards can be shown to have quite large differences for instance.

For most people, digital camera advances are getting smaller and smaller over time, particularly with more automated editting and the main display format being screens rather than print.  Making it clear that the practical difference means you cant lose can be rather helpful for people anxious about whether they have to worry too much.

Underwater macro often uses AF too, for fairly obvious reasons.  Supermacro, tripods etc and/or rock back and forth start getting used more.

You keep working backwards though - if the yield for FF is high enough, the increased rate of failure becomes more and more irrelevant.

You quoted 90% or APS-C, but I dont see where that came from vs FF max rates possible - what is the max rate likely, and is 99, or 99.9 or whatever possible at some point or anything? The usefulness of your figures rest mostly on how often FF have to be failed, and to me thats the rate that we need to know about most.

Edit: So we seem to agree that the differences get smaller and smaller where the sensor price becomes comparatively irrelevant ie we talk 7 vs 30+ times.  The 6D price alone shows either dumping is occurring, or the price of sensors are getting very low as part of the total cost - any improvement is going to have to be pretty amazing to overcome the introduction cost of something new with 10% rates etc etc.

The actual die yield rate matters quite a bit though doesnt it?

As in if you get 1 failed sensor out of 1000 for a full frame, its not going to really matter all that much that its even only 1 in a million for the APS-C sensors.  Its going to be much closer to just the actual 1.6 square, ie about 3 times as much.

So depending on the numbers, we could be talking a $10 sensor vs a ~$30 one, or 10 vs 340.

The gap in price between the 6D and and a 60D or the like does seem surprisingly close though.

Summer in Oz!  But our problem will be more wanting to go outside because the streets are melting rather than the snow.

Also because of various changes in exchange rates and $1000 custom limits, its gone to something that might be 50% more in price Oz dollarwise compared to a year or so ago.


As a non-USian early adopter, getting a weeks late letter saying Ive been hacked, getting nada othe than a compulsory PW change, then seeing this deal only apply to new customers in the US, I cant say Im overly impressed.

It was still cheaper than buying the old version in Australia, but talk about the lustre being gone.

Its less pixel peeping and more cropping for me.

With both the tamron biglens update and the 7d2 appearing, it will either be very exciting or time to accept I have to accept the limitations of what I can achieve without relying on technology to help it further.

If they could make sure it fits my 7d underwater housing too that would be great . yes I know I'm dreaming.

I end to agree the main reason is most people have bought a DSLR already and cant see the point of gettng another.   The people I know with one mostly use it only for special occasions like birthdays or holidays, and for everything else its camera phones.

As in theres my friends and I who do bird, art or underwater etc, but your average mom or pop, they're done.

I have tried on android and ipad, find its not really very workable unless its for like one image for some quick sprucing up, not much different to what you'd do to a jpeg.

The apps are just too clunky for anything else but hopefully someone else has worked or found something out that Ive missed.


EOS Bodies / Re: What do you think will be the Shelf life of the EOS 6D ?
« on: October 19, 2013, 06:31:23 AM »
I broke the rear 6D LCD screen with my Ipad which I also broke.  Its a cover rather than the actual screen so it still worked fine, just looked ugly.

It was about $100 to fix, for people who worry about doing that often a protector might be worthwhile, for me it was a relief to know if I somehow manage to repeat that level of bad luck/silliness, the cost is relatively minor anyway.

That photo above makes the point IMO - a 70-200mm sure.  A 50mm 1.8 or other consumer grade lenses?  Not so much unless you have storage space galore.  Also unless you can show the lens is in very good condition, it probably wont be much help either.

So  it depends on what it is, I still have my 40D box, but I doubt its going to get me much extra given its had a pretty hard life as well as getting on a bit.

Autoboot was solved on the 7D a couple of weeks ago and is now very simple.

I guess we have pretty different ideas about what 'very simple' means.  That post is from yesterday, a more detailed and helpful one is here:  http://www.magiclantern.fm/forum/index.php?topic=7464.0

Its prefaced by "this is a guide only for if you want the VERY EXPERIMENTAL and POTENTIALLY DANGEROUS autoboot version of the beta 2".  Partly bum covering of course, but not complete hyperbole.

Things are progressing quickly and theres some very promising stuff happening, but also it means levels of testing in the wild are going to be much lower.

Thats true for most cameras where its a single DIGIC chip, but the 7D is pretty different with its dual DIGIC 4 setup, and a real alpha in my view. 

The problem with ml on the 7d was to get it to start at all, and now they managed to find a way, but afaik just like on single digic cameras ml is only using/running on one cpu, so it's not like the whole thing needs to get rewritten.

If ml used to brick cameras it was mostly because invalid values were written to the Canon fw, the result was that the cameras refuses to respond until you de-brick it with a special mini-firmware. But nowadays ml reverse engineering has a very good idea what valid values are and they check them before setting them, so the main risk is contained no matter how many cpus are on the pcb.

Alpha doesn't have to = bricking risk, but there probably is a greater risk of bricking with the 7d compared to the other cameras, if not massive.   The main limitations is that some functions aren't single digic only, so it needs extra work to get some things going, but isn't a particularly high priority camera to merit the extra effort, hence its ongoing alpha status compared to 5d cameras.

Also the firmware doesn't boot in the same way, and to get auto boot going is a much more laborious and in my view higher risk process.   So any new features go on top of those again.

All sounds great, but given the 7D ML is still at alpha stage and has been for some time, this is more a theoretical achievement than actual.

"Alpha" is more a label to scare people who don't know what they're doing, since the ml framework is very stable by now a port to a new camera is also expected to be stable. So the "alpha" label more relates to the fact that you shouldn't *rely* on it for production and it might not be feature-complete then that it's likely to brick your camera.

Btw raw on the 5d3 will still be better than 7d because I'd expect the 1080p data rate to be too high and 720p has moire.

Thats true for most cameras where its a single DIGIC chip, but the 7D is pretty different with its dual DIGIC 4 setup, and a real alpha in my view.
