Underwater / Re: Australias Leafy Sea Dragon
« on: September 20, 2014, 06:41:37 AM »
sorry mate but if the locations of theses were known on the internet or any body in the hands of aquarium hunters they would be decimated in weeks, it took me over 4years to locate them and I had been at this location many times, the only way I found them was by them accepting me and this little dragon was hanging around for over 3 hours in very still waters, I was very lucky but I watched this one for over an 3 hours and I had only a mask and flippers on at the time I believe they shy away from the full diving equipment and noise.......

Should explain Im an underwater photographer based in Melbourne - amateur, but done hundreds of dives here and pretty well connected to that community here.

Several locations of these creatures are already well known on the internet, but if it really is close to Melbourne the location probably is a bit more risky as poaching does happen I agree.    There has been the very rare odd juvenile that is found at Flinders pier, but they never seem to last long and the general guess is they've been blown in by a storm.   I have never heard of anyone finding an easily accessible ongoing population in the Melbourne area, let alone over 4 years in recent times, there were reports of them being more common in the 80's.

Ive photographed them several times at Rapid Bay in SA which is one of the well known locations for them.  They can be found down to 50m, although I have seen them there in 5m, so thats some pretty impressive snorkelling photography for 70 years old.   They're  actually very easy to photograph as they're very slow moving, the main issue generally is finding them as they have good camouflage in their habitat and doing it from an interesting angle and background as well. 

Similar to others, some exif data and the full picture would be interesting to see.

We do have the fairly famous Melbourne Aquarium with quite a few in them, so it isnt hard to see them in an aquarium setting here.

As someone who dives here in Melbourne, this must have been a very lucky find, as by far the majority of seadragons found here are weedy, not leafy, which are generally found far more easily in South Australia. 

If you could give a bit more info on the general diving location, it would be very helpful as an actual colony in the area would be a great find.

The 7D II is similar to the 7D in that it has 2 Digic processors, which delayed magic lantern work on it for some time, and has caused ongoing problems with its development.

I wouldnt put too much hope on that being the answer at this stage, particularly given most work tends to be focussed on the 5D series anyway.

I think thats about right for electronic repairs, the problem is you read about USA Canon policies so its quite a shock when you find out how different it is in Oz, and apparently Germany as well.  I had similar for the 50 1.4, and didnt even bother to get a real quote when my 7D finally went, the rough estimate at least saved me the $50 quote.


Software & Accessories / Re: Gimbal head or not for Tamron 150-600
« on: June 16, 2014, 07:36:20 AM »
I have the Tamron 150-600mm and recently got a NEXT carbon fibre gimbal and Sirui tripod, complete overkill given the lens weight but I have noticed a fair difference. 

Now for me, Im not great at getting very low shutter speeds even with VR, so thats the subjective factor I guess, and I dont do much better with a monopod.  The downside is carrying it about so its not useful for every scenario, but I do much prefer it over the ball and pistol tripod options I have instead.   I dont find the zoom impact on balance to be a major issue as Im generally going for 600mm if Im using it anyhow, so its dialled in for that.

« 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.


EOS Bodies - For Stills / Re: 7D vs. 70D: Which has better image quality?
« on: February 09, 2014, 11:41:37 PM »
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.

Lenses / Re: Canon EF 100 f/2.8L IS Macro autofocus?

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.

« on: October 27, 2013, 08:26:42 PM »
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. 


Software & Accessories / Re: Raw processing on iPad/tablet
« on: October 25, 2013, 07:06:50 AM »
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.
