Lenses / Teleconverter crop factor conundrum
« on: August 09, 2014, 01:27:09 PM »
I'm considering buying a 1.4tc to go on my 400mm 5.6. I've often wondered, which is better in terms of IQ:

Using 400mm (no tc) on 60d?
Using 400mm on 5d3 and cropping?
Using 400mm on 5d3 with a 1.4tc?

These options all yield a similar focal length, but which would give a better overall result?

Cheers

Lenses / Tamron 150 600 woes
« on: August 02, 2014, 01:04:01 PM »
Bought a tamron 150 600 for my 5d3 and 60d. It has AFMA problems (-6 tele, +5 wide)

Sent it back for calibration. Came back worse (-15 tele, -5 wide).

Gave up and I'm sending it back for refund.

Anyone else had problems with this lens?

Software & Accessories / Think tank logistics manger 30
« on: July 05, 2014, 06:51:56 PM »
I have a 5d3, 60d and about 10 lenses including tamron 150-600 & canon 70200 2.8 ii

Does anyone use the think tank logistics manager 30 for storing DSLR gear at home?

I'm thinking this could be a 1 bag fits all solution to store all my lenses and gear but I'm struggling to find many example pictures on the net of what this could fit in.

Anyone got one?

THanks

Lenses / AFMA Oddity
« on: June 29, 2014, 06:46:29 PM »
I have a question about afma.

I have 2 bodies (60d and 5d3). They are both calibrated to be the same and All my lenses need no afma adjustments   


However I just bought a tamron 150 600. On my 5d3 it appears to near +6 on the tele end and -5 on the wide end. However my 60d seems to be fine with it.

Is this possible? Or must my tests be wrong.

Lenses / Need a 600mm. Don't want to pay for one
« on: June 03, 2014, 04:39:46 PM »
I want a 600mm focal length for zoos on my 5d3 but I can't afford the big canon glass.

The options I'm considering are:

Tamron 150-600 @ £950

or

Sigma 120-300 Sport @ £2500 + a 2x TC

I can afford either of these options but not both. My question is, which will be better at 600mm? considering, IQ and AF speed.

I have the canon 70-200 2.8ii so the sigma for its 120-200 range doesn't excite me (neither does the cost or weight). but 300mm f2.8 excites me, so does 400mm f4 but I not sure about 600mm via a 2x TC.

Have anyone come across a direct comparison of these two routes to 600mm?

All opinions greatly welcomed.
thanks in advance.

Software & Accessories / Chuck a 5dmk iii in a rucksack
« on: April 18, 2014, 01:31:12 PM »
I'm looking for something to protect my 5d mk iii (with 24-70 2.8 ii on) so I can carry it in a normal rucksack and be confident that it won't get scratched.

Mild splash protection would be ideal but not a necessity.

I'm thinking something like a neoprene style wrap (which I've seen lurking around, but nothing 5d3 friendly).

Anyone got any good recommendations?

Thanks

Lenses / what lenses have you sold in the past and why?
« on: February 25, 2014, 08:22:13 AM »
I see lots of posts re: "what should I buy" but I've never seen any on what people have got rid of, and more importantly why.

Here is what I've sold in the past and why (in order).

Canon 18-135 - was never really impressed with the IQ. Always left me wanting more.

sigma 24-70 2.8 (v2) - AF wildly inconsistent. Bokeh very unattractive (I would call it 'crunchy'). I never really trusted this lens, or liked the photos it took. Sold it for canon 17-40 on a whim, as I needed a gen zoom quickly for a holiday.

canon 17-40 - The IQ, flare control, contrast and AF were all great, however I was never excited by the zoom range on crop, so sold it for 17-55. However I regretted selling it once I bought my 5d3.

canon 2x TC ii - I bought it when it was mis-priced in a local camera shop. However, the IQ was crap so I never used it.

Canon 7d - was a great camera, but after 3 years of (heavy) shooting it started to show signs of wear so I decided to go full frame and replaced it with a 5d3.

Canon 85 1.8 - sold for 85 1.2 ii. However wish I kep the 1.8 aswell as sometimes the f1.2 is just to big/heavy/slow AF to use out and about (althought when it nails it the results are glorious).

canon 50 1.4 - sold for 50L 1.2. Best decision I ever made. Wish I did it 3 years ago. It now lives on my camera.

canon 100mm macro - a lovely lens. However I took it to a humid butterfly farm which killed the aperture blades (they got stuck). I got it fixed by an authorised canon repair centre but it was never the same lens after I got it back. It still worked fine, but the AF was so slow after. So sold it, on the cheap :(, and replaced it with the 100L

canon 17-55 - just sold it as I upgraded to full frame and no longer really use my 60d (I keep my 60d for backup purposes and when I go to the zoo). Plus to be honest, I've never really been impressed by wide open IQ or contrast. Given my shooting style (run and gun) I don't really have the need for IS and I prefer shooting at wider apertures than f2.8.

sigma 10-20 - A wonderful lens. Never had any complaints, however I no longer use it because I upgraded to full frame. so gonna purchase a FF equivelent like the sigma 12-24 or canon 16-35.

Lenses / General purpose zoom for honeymoon
« on: February 25, 2014, 07:55:02 AM »
I'm heading on my honeymoon in April to Mauritius for 2 weeks.

At home, I shoot 5d mk iii and generally with primes (24L, 35, 50L, 85L, 100L macro and soon to have 135L).

I'm thinking of not taking any of those and just buying a general purpose zoom so that:

a) Im carrying less stuff (so my new wife doesn't kill me for taking so much stuff), and
b) I can focus on enjoying my honeymoon and taking snaps rather than worrying about having the right lens on (so my new wife doesn't kill me for taking so much stuff).

I could just take the 24, 50 and 135 + an extension ring and that would cover most scenarios. However on a general walk about I'd still be carrying 3 lenses.

I'm sure this has been covered before (somewhere) but I think my options are:

The canon 24-70 ii feels too expensive to justify.
The canon 24-70 f4 doesn't feel exciting enough (70mm @ f4) to warrant £1000.
The canon 24-105 f4 could be a reliable choice but its dated and I worry about sharpness and sample variation.
I like the look / idea of the tamron, but the stories I hear about AF inconcistency (not MFA) worry me.

So I'm kind of leaning towards the sigma 24-105 f4. But I've owned the old sigma 24-70 f2.8 in the past and found the AF to be unreliable and the bokeh to be unattractive. But I could save a bit of cash and buy a used canon 24-105 f4.

But does anyone have any good opinion (or bad opinions) of the sigma 24-105? and/or any decent and definative review sites? and/or does anyone have an opinion on whether the canon 24-105 would be a better bet?

And/or any other suggestions that I haven't considered?

Your time is always appreciated.
Thanks all
Alex

Software & Accessories / Short term gear insurance UK
« on: February 02, 2014, 05:30:35 PM »
Wasn't sure where to post this so apologies if there was a more appropriate place to post this.

I'm going on holiday for 2 weeks in may. I was wondering if anyone knew of an insurance company that did short term insurance UK?

I'm wanting to cover 5d3 + many lenses and my holiday insurance won't cover that value

« on: January 27, 2014, 05:22:47 PM »
Does anyone know of any reviews of the Vanguard 53F or 53D hard case? Any opinions? Sample pictures illustrating how many lenses it can store would be useful. thanks

Software & Accessories / Wrist strap / handgrip recommendation?
« on: January 22, 2014, 08:12:45 AM »
I shoot a lot on the street with 5d3 and either 35l, 50l or 85l. I don't like to use my neck strap (or black rapid) because it attracts to much attention. I'm after a wrist or hand strap that is secure.

Any recommendations?

Lenses / sigma 15-30
« on: January 15, 2014, 08:12:18 AM »
Has anyone tested this lens on full frame? (specifically 5d3)

I really want a super wide (something 16mm or wider) but I don't really want to spend to much as generally I only use superwide to exagerate perspective / fun creative shots rather than serious landscape or architecture.

I've seen a preowed copy of the 15-30 for £140 and wonder is it cheap because its rubbish?

Any opinions or sample shots would be really appreciated.

Software & Accessories / Lens storage for checked in luggage
« on: September 09, 2013, 03:29:01 PM »
I'm going on holiday next week. I'll be carrying a bunch of lenses in my suitcase which will obviously be checked into the cargo of the plane.

I really like the look of the betashell cases but I'm not convinced their available in the UK.


Can anyone recommend some good sturdy lens cases suitable for 70_200 2.8 is ii, sigma 35mm 1.4, canon 24mm 1.4, canon 100mm macro L?

Must be uk available stock.

THanks in advanced.

Software & Accessories / Transcend memory card problems
« on: September 08, 2013, 12:50:59 PM »
historically I have always used sandisk extreme cards (both SD and CF) as I've never had any problems.

Recently I won a competition and got a 32gb TRanscend UHS SD card for free. I put it in my rx100 and so far it has failed on me 3 times either:

not being recognised
deleting all images on the card; or
refusing to be formatted.

I wont be using it again for anything I care about so I might just stick it in a digital photo frame.

Does anyone have any similar experiences with Transcend cards?
