Software & Accessories / Re: Gimbal head or not for Tamron 150-600
« on: June 16, 2014, 07:11:19 AM »


Bear in mind that the Tamron is not the sharpest lens on the block, but is sharp enough and provides more fun per $ or ounce than most telephotos. One of its greatest advantages is its light weight and zoom. You nullify these by adding massive expensive gear that might get the best of a supersharp heavyweight that outresolves the sensor but might not increase the sharpness of a less refined lens.

I think we will have to agree to disagree on this point.
Whilst I don't think a 5 series Gitzo is necessary a good Feisol 2/3 series (or similar) with a decent Gimbal would net the best results without spending silly money.
Whatever the price or weight of the lens, it is the focal length that matters. You state that the Tamron is not the very sharpest lens going, surely this makes getting the very best out of it even more important?
If light levels are good then no support is necessary, but that isn't always the case.

Just my 2p!
I am having to disagree with some here - sorry!
If you are going to use the Tamron, at 600mm, then you must treat it as a 600mm lens to get the most out of it. The fact that it is very light is, if anything, a disadvantage when shooting as the Canon/Nikon 600mm behemoths damp down  a great deal of vibration by sheer weight!
You will need top quality support (tripod) and a top quality head. I would not go for a Ball Head as you will VERY quickly find it VERY frustrating. With a ball head positioning/framing will be difficult and moving subjects will be out of the question. A Gimbal (such as the Jobu Jr recommended above) is probably the best compromise. Unfortunately, if you change focal lengths, then the balance will alter - but it is still the best solution.
Make sure you have a good, very rigid, tripod (forget the weight ratings) that will support your lens and not shake all over the place with these sort of focal lengths - sorry but that means an expensive tripod!
Be prepared to spend more on your tripod and head than you did on the lens if you want to get the most out of it.

We will all just have to wait and see!
Canon are not going to produce what I want ( a 10/12mp high ISO, fast apsc camera) as too many people out there are convinced that the current 18mp+ apsc sensors gives more "Reach" - I have tried them - they don't really, well just a little but with a whole host of compromises, in the real world larger sensors win hands down.
Let's hope the high MP fans don't win and that they (Canon) actually produce a useful upgrade over the 7D!
Many will disagree with me - that's fine - but I have tried them all (Canon's and the better Nikons) and the larger sensor lower MP cameras produce the goods. High (12mp +) small sensors are just too much of a compromise.

Lenses / Re: What was your first L lens?
« on: June 10, 2014, 08:43:49 PM »
First was the 100-400, then 17-40. However it was just the start of a slippery slope!
I am currently running the following "L" lenses 17-40, 24-105, 70-200 F2.8 IS, 300 F2.8 IS and 800 F5.6 IS, no wonder I am skint!
The first step is admitting you have a problem, the second step is...where's my credit card? There's a new L lens coming out...I'm sorry, what were you saying?
 ;D

I don't have a problem - I am just an addict who does not want a cure! The credit card is fine, I have no debts but a 600 Mk2 - possibly a 300 F2.8 Mk2 and loose the 17-40 + 24-105 for a 16-35 F4 and 24-70 Mk2.......
well maybe I won't be out of debt for long!

1. To me 18MP is plenty - I wouldn't mind more but only if there was NO compromise in ISO performance.

2. I am not having issues with DR, more is obviously better just not a particular issue to me.

3. I am finding the usable ISO range on my 1DX great, again more would be better especially below ISO 50.

4. Mirroless cameras are of zero use to me. When they can AF fast, have a viewfinder/screen that I can use in real world lighting conditions, balance properly on large lenses and have a decent size battery - then I will be interested.

5. Switch brand? Only Nikon offers the sort of lens range that I mainly use - tried a couple (with D800e and D4) - staying with Canon for foreseeable future.

6. Don't find much use for IS on my 800mm F5.6 - on a wide angle? No thanks - it just adds another (dead) element that serves no purpose for me and IS slows down AF..

7. No idea - so long as it works I am happy!

8. DSLR's have Video?

9. Err no.

Children please stop squabbling!
If Canon don't make the high MP camera that you think you want/need the go buy from someone who does. It is pointless going on ad infinitum about what they don't make, if you really want 30+mp go buy it and stop whingeing. If there are enough of you then Canon will change their products - though when you discover (as I have) the advantages of more modest MP sensors we will welcome you back.

Yes that's right I am quoting myself!
I wish to retract this post as I feel it detracts from this thread, sorry for posting it folks.

I am having so much fun reading the complete ** here that I don't want it to stop! I am having a great laugh at it - please continue! It is a bit disappointing to read the lack of knowledge/experience of many posters (and I don't claim to be an expert) however it is quite amusing so please don't stop.

Lenses / Re: Canon EF 300mm f/4L IS USM Lens - Sharpness
« on: June 07, 2014, 06:57:33 PM »
Unfortunately I had to sell my Canon 300 F4 IS as I also have the Canon 300 F2.8 IS and couldn't afford to keep both. Whilst my 300 F2.8 is better in all respects (except weight and price) the difference is surprisingly small.
I originally bought my 300 F4 as I was looking for more reach than I had with my Canon 100-400 (yes read that again). A cropped image from the 300 was better than I could get from my 100-400 at max focal length. A friend of mine (after trying my 300 F4 and a couple of others) made exactly the same switch for the same reason - reach.
I never bothered much with extenders on my 300 as I had the 600 F4 IS, though my friend, mentioned above, has had good results with both his Canon 1.4 Mks and his 2 x Mk3 (in very good light).
What the above boils down to is that our two 300 F4 L IS lenses are very sharp by any standards and the images could stand far more cropping than we expected. For reference the cameras used were a 1D3 and two 1D4's.
It is an old design and not perfect (the IS is clunky so just turn it off!) but there is absolutely nothing wrong with the optics.

Fourteen stops. HAH! I fart in the general direction of your fourteen stops! And Laugh. MUHAHAHAHAHAAAA!

I think the message taped to an Arrow & shot into the Chest may have had more impact & been more pointed   ;D

Love those Movies.

Me too! :D

Obviously not a Troll as he didn't say " I don't want to talk to you no more, you empty-headed animal food trough wiper! I fart in your general direction! Your mother was a hamster and your father smelt of elderberries!"

P.S. a friend of mine was an extra in the battle scene at the end of the film.

Lenses / Re: Need a 600mm. Don't want to pay for one

There might be a bit of a wait for the Tamron.  Orders placed in mid March at B&H haven't been filled yet.  I'm also on the waiting list at the local camera store.  At this rate I might save enough for a big white before the Tamron ships. Been thinking the 300 f/2.8L IS II was the next step for me since already have the extenders, just thought I'd be waiting until a year or two after I got the Tamron.

Honestly if the Canon 300 F2.8 L IS Mk2 is a bit of a stretch (it ain't cheap!) then have a look at a used Mk1. IQ wise there is little between them, yes the Mk2 is better but it takes a Guru of heightened enlightenment to really see the difference.

Not entirely true. Without tc's I would agree with you, but once you add a 1.4 and especially a 2.0 tc, the difference in iq between the 300i and 300ii is significant and immediately noticeable. AF performance is also significantly improved on the mark ii over the mark I.

Interesting - I didn't really see much in it, and then only by pixel peeping, though I would definitely agree on the AF improvement on the 300 Mk2 + Mk3 extenders over the Mk1 with the same extenders.

Some very interesting comments and food for thought - thanks.
Perhaps I should have stated at the beginning that my primary interest is wildlife photography, generally with long lenses and rarely at the lowest ISO. In this type of photography I feel that DR may be a lesser consideration compared to my camera's and lens's capabilities?

EOS Bodies - For Stills / Re: Canon 1D Mark IV or 1Dx?
« on: June 04, 2014, 04:49:01 PM »
Looking at UK prices you'd be able to get a used 1D4 and a 300/2.8 I for about the same money as a new 1DX

Where? A good, used, Canon 300 F2.8 L IS Mk1 is 3K+ a decent 1D4 is 1800+. That adds up to a lot more than my 1DX cost!

The cheapest 300 f/2.8L I IS lens right now is $4500.  Cheapest 1D Mark IV I could find in decent shape was $3000.  Assuming you could buy a used 1Dx for about $5400, you would still have $2k left.

I should have said that those are UK prices. So a 300 F2.8 IS Mk1 + a used 1D4 would run around 4800 vs the 3600 that my 1DX cost new. The difference is about 1200 GBP/$2000 US so we are in the same ball park!

mackguyver - you obviously have much better technique with this setup than I do! If it works for you then that's great, but I had problems.
I found it pretty good with the 70-200/300 F4 and smaller, also it is cheap and light.

That RC2 plate can catch fingers if you put them in the way.  However,the current ones, at least,  are designed to snap closed so that you do not use fingers or even keep them near the lever, just lower the plate into the clamp front first and then press down on the rear of the lens or camera, the weight is usually enough,  and the clamp snaps closed.  Then, push on the lever to make certain that the lock is engaged, because it does not engage reliably.  No pinching of fingers when you do it that way.

The pinched fingers were caused by the lens tipping, not by the QR lever or plate.

No advice - I just misread the post and it reminded me of my, then, 3 year old grand nephew running around with my 1D4 and 24-105 at Christmas a couple of years ago. The camera was as big as his chest and he found it VERY heavy! He got some cracking shots though!

Awesome.  She doesn't like my 6D as she tries to swipe at the screen to look at the next picture and she says with a pout "it's not working."

 :D!
