EOS Bodies - For Stills / Re: Removal of IR Highpass filter
« on: October 16, 2013, 09:41:56 AM »
I'm looking into getting the IR filter removed....

...but am also considering removing the AA filter too (a 450DE one might say). However this would remove the dust-removal feature....  anyone done this? was sensor dust then a problem?

From the diagrams I've seen, it appears that the IR cut filter and the horizontal part of the AA filter (along with the 1/4-wave plate) are all stacked together in the assembly that is piezoelectrically vibrated for 'sensor cleaning'.

I thought that in the 450D the AA + dust removal where a singular, separate, unit to the high-pass (it is a high-pass right?), though your wisdom being what it is i will definitely re-check. Does that mean that even removing the IR-cut would abolish the dust removal system (DRS), or only once the AA filter is removed will the DRS be abolished?

EOS Bodies - For Stills / Removal of IR Highpass filter
« on: October 16, 2013, 09:12:54 AM »
Hi all,

How many of you guys have removed the IR highpass filter in your DSLR.  I have an old, abused, well loved but unused 450D sitting around and i would love dearly to breath some new life into it. I have tried to sell it but to be honest the street value of it (lensless) is not worth me selling....  this was my first camera, and well, i love the little fella! :) As such, I'm looking into getting the IR filter removed....

How many of you guys have done this? any advice? I don't think i will replace it with another filter (e.g. Baader BCF), but am also considering removing the AA filter too (a 450DE one might say). However this would remove the dust-removal feature....  anyone done this? was sensor dust then a problem? :)

Thanks for any advice/experience in this area!

John

I'd vote for the 15-85. It is a great lens.

Heard good things about it too, and with great versatility...  My main question would be, are you planning on moving to FF soon? That might be the only reason for the 17-40....

EOS Bodies - For Stills / Re: "Downgrading" for a very specific reason

All of these are very good points and interesting arguments....

I think if i were to start photography again, i would not go down the same path i did, but would buy an older second hand camera and a good lens. This thread is an argument for doing just that! To all the "what should i buy" guys out there...  pick up a used 5D I, and a 50mm instead of the newest XXXD kit...

Beautiful things happen every day, all the time, but mostly unnoticed by the masses, let alone captured. Great shot and well done. Sadly, I too have no similar shot, but many of my favourite shots are complete chance encounters. The lesson all over us need to remember is that luck favours the prepared!

Firstly, i would highly recommend taking a lens! :P

Although i have not been to Hanoi, In your situation i would slap on the 35 and go nuts! Get nice and close and dive into the action. Sure take the 135 is you want some length, but i would certainly have the 35 on for >90% of the time (I usually just leave my 24mm on when going to cities...  but i like wide and don't mind cropping if needed).

Either way, have fun! :)

Street & City / Re: 5D3 and ISO 51200: Firefighters rehearsing Emergency

Nice shot...  I think grain/noise actually adds to this shot! :) In low light, i often like noise in the shot (certainly a lot more than the 'plasticy' look of overused noise reduction). Often when the light is too low for 'normal' iso ranges, the noise of the image mimics the poor visibility our own eyes suffer in these situations, adding to the mood of the photograph. Use noise/grain, don't fight it! Anyway, i digress...  great shot. :)

Lenses / Re: Longer and faster, better?

I guess i will start saving....  by the time i have enough tucked away for the version II, i might have managed to persuade my wife it is necessary! :)

Good decision.

I too am saving up for the 300 f/2.8 II. The purchase will be funded in part by the sale of the 100-400. Not too sure though that I'll try to persuade my wife though ... I risk getting whacked over the head with one of the white lenses if I'm not careful ... this is one hell of a hobby!

I bought my wife (and me by extension) the 100D + 40mm STM....  Now she is asking to borrow my 24-105 for more length...  I'm hoping she will see the need herself and realise if i'm using the 300, she can use the 70-200! Well, thats the plan at the moment! ;)

Lenses / Longer and faster, better?
« on: October 11, 2013, 01:59:11 AM »
Hey,

I am doing more and more wildlife photography (bit difficult not to living in India), and am thinking about getting a longer faster lens.

Most of my shooting is early in the morning, in the jungle/woods. every time i hope to come across tigers/leopards/bears, but these sightings are rare, so i amuse myself birding.

Currently i use a 5D MKIII and my 70-200 + 2x tcIII. The f/2.8 gives me the speed in the wee hours, and i pop on the TC when i need length and the light is better, but it is always a trade-off, and often i find myself in the situation where 200 is too short, but with the tc on the ISO/shutter speed is no longer ideal (there is an obvious point where i think adding the TC vs more extreme-cropping yields comparable results).

I am thinking about a 300mm 2.8, but the new version II is a little out of my budget. So either a second hand version I or maybe a Sigma EX 300mm f/2.8 APO DG HSM.

Any other suggestions? Has anyone any experience with the Sigma? How well does it take TCs? unfortunately TDP does not have the sigma in their comparison charts.

I guess this is more of a feasibility study for me. I'm trying to find the right/best price point.

Renting is an obvious solution for longer lenses, but it is not so easy here...  the few places that have these lenses are so overwhelmed, you need to reserve your lens weeks, if not months in advance. I am just not that well organised! :)

Thanks

Lenses / Gateway lens
« on: October 09, 2013, 08:08:00 AM »
Photography is like a drug habit.... You get your first hit, and your hooked...  you start off small (usually) then build up to the heavier stuff, and the heavier the stuff the more you want to use! So what was your 'gateway lens'? When and what was the lens or other bit of kit that broke your barrier and led to the reduced coffers most of us face due to this pricey hobby.

For me it was the EF-S 17-55. Before that I had a 450D and kit lens + 50 1.8 for years and could not imagine or ever conceive a situation where i would spend more than a couple of 100$ on a lens.  Then i borrowed and subsequently bought the 17-55, and in doing so released the kraken. I had waited 2 years before buying it, but after that i added a 10-22, 55-250, tripod, 580ex II etc to the kit within a year...  then came the L lenses.... 

So, for a bit of fun, what was your gateway lens/piece of kit?

Never knew this lens...  would you mind doing a comparison (if possible) of the 400 f/5.6 + 2xTC vs 800 f/8 on the same body (5D).  It would be more informative as a comparison...  or even 400 cropped vs 800 on the 5D. :) but comparing two different lenses on two different bodies is difficult! :)

ps - I like obscure lenses!

Pick up a used Nikon and you will have yourself a bargin, but awesome, wildlife set-up! :)

things that might be enough to shift systems, and as far as i am concerned, I would not question that decision (assuming you use it enough).

Nice bargain, enjoy!

Thanks, great idea...  but i can imagine the places you can't use Tripods won't like you bringing in a length of chain...  since it is a pretty deadly weapon! I think a retractable cord might be more appropriate!

Does anyone use this site to register your equipment. Does anyone know of any success stories etc?

Thinking of signing up, but wanted to know if it is real/good/a scam.

Thanks
