Canon General / Re: What is your Least Used Piece of Gear?
« on: Today at 03:33:12 AM »
The least used item in my bag is my Vivitar 19-35mm. It has been largely replaced by my 24 IS, which is far better, as good optically as my OM Zuiko 24 but with the benefit of IS. I keep the Vivitar only for when 24 isn't wide enough, which is rare.

I also have a Vivitar 70-300, completely redundant since buying my 70-300L. In common with others, I have an old light meter, but find that my iPhone does the job.

Hi folks.
There is a water and object ingress standard at least in Europe, IP XX, where the first number stands for objects and the second for water, I  think it was something like IP 00 means you can get an industry standard finger in there, and water that runs in runs out and IP 67 means that dust has to be below so many microns and you can pressure wash the item and water won't get in.. This is just from memory so feel free to correct me!
Anyway back to the point if it doesn't say IP XX on the label it isn't weather or water resistant!

Cheers Graham.

Agree. That is the standard most commonly used in America as well as internationally. Most of my flashlights are IPX7 ;D  Camera manufacturers simply choose to not use them.

 IPX Standard Code Meanings

 IPX-0     No special protection
 IPX-1     Protected against falling water Equivalent to 3-5mm rainfall per minute for a duration of 10 minutes.
 IPX-2     Protected against falling water when tilted up to 15 degrees – Same as IPX-1 but unit is tested in 4      fixed positions – tilted 15 degrees in each direction from normal operating position.
 IPX-3     Protected against spraying water – Water spraying up to 60 degrees from vertical at 10 liters/min at a pressure of 80-100kN/m2 for 5 min.
 IPX-4     Protected against splashing water – Same as IPX-3 but water is sprayed at all angles.
 IPX-5     Protected against water jets – Water projected at all angles through a 6.3mm nozzle flow rate of 12.5 liters/min at a pressure of 30kN/m2 for 3 minutes from a distance of 3 meters.
 IPX-6     Protected against heavy seas – Water projected at all angles through a 12.5mm nozzle at a flow rate of 100 liters/min at a 100kN/m2pressure for 3 minutes from a distance of 3 meters.
 IPX-7     Protected against water immersion – Immersion for 30 minutes at a depth of 1 meter.
 IPX-8     Protected against water submersion – Equipment suitable for continual submersion in water under conditions as specified by manufacturer.

I would much rather see IP and 2 numerals, not IPX and 1 numeral. The X signifies lack of a rating for dust ingress, and we need that too in some environments. IP 65 and upwards are the standards that camera and lens manufacturers should strive for.

When on an already expensive holiday to the other side of the world, I hired a 70-300L. With Aus prices one third below the UK price, and a refund of the hire fee, I couldn't fail to buy it.

Warranty is with Canon Australia, so should there be a problem I can at least send it to my sister to take care of it there.

I have considered the Pentax K-3 someday for more reliable weather sealed protection.

There is a lot that I like about the Pentax K3.  Their actual weather sealing is impressive. Some of the YouTube vidoes showing people abusing their K5/3s and they survive nicely are impressive.

If Pentax were to come out with a FF camera, IBIS, actual weather sealing and a few good FF lenses.......I would be really pissed as I already purchased my new FF system.   ;D

I still wonder if a K3 would not have been a better choice.  That is a sweet camera.


If I had not decided to go full frame, Pentax would have been my choice (K-5 IIs at time of purchase). I'm liking my father's K-30, and Pentax have a wide range of APS-C primes unmatched by Canon. Their weather sealed lenses also start at a much lower price, similar to Canon's price for non-weathersealed STM lenses. As the underdog in a world where Canikon is the default answer, they try harder.

I think that you are safe on Pentax not offering a FF camera - the 645Z is their bigger and better answer to that. I chose Canon full frame because it was the right balance between optics and usability/portability for me.

That would be daft, just a 'me too' alongside Pentax, Leica, Hasselblad, etc.

If starting a new lens system, the smart move would be to launch a mirrorless MF without the bulk caused by the enormous flipping mirror.

EOS Bodies - For Stills / Re: Manual Focus using 700D - Wow!
« on: August 01, 2014, 02:05:24 AM »
After reading this I'm very tempted to by the 100D that I've long promised myself as an every day camera. I too prefer primes, and the option of switching primes between crop and full frame bodies for different field of view makes a lot if sense to me.

Meanwhile, I've just spent all my funds on a new Mac, so will have to wait a while....

If any piece of electronics gets wet, don't seal it in a bag because that will keep the moisture in and worsen the problem. It's much better to find some shelter and let the camera dry out in circulating air. The only exception is if you have some desiccant with you (eg uncooked rice) and put it in the bag with that.

My 6D with non weather sealed lens dried out fine on a car seat after a few minutes thorough soaking in the rain.

I'm just waiting for the first mirror medium format. If full frame mirror less can be two thirds the weight of a full frame, then the result could be excellent IQ from a body weighing only 1kg

I'd like 2-3 more C# settings.

me too!

How would you remember what they are ? I have trouble remembering 3 !

How about named custom settings accessible via a rear touchscreen, instead of numbered on a dial. Memory problem solved.

Canon has been updating the budget lenses with IS STM versions, so I think there will be 3 new normal focal length lenses:
1. An inexpensive EF 50mm f/1.8 IS STM lens (to replace the plastic fantastic)
2. A mid-tier EF 50mm f/1.4 IS USM (to replace the EF 50mm f/1.4)
3. A pro-level EF 55mm f/1.4 USM (To replace the 50mm f/1.2)

I suspect that Canon have already filled that budget niche with the 40 STM. It shares the absence of a focus scale with the old 50/1.8, at moderate extra cost.

Lenses / Re: New Canon L Primes, but Not Until 2015 [CR2)

I'd love it if they updated the 28–135 to be a 24–135, to be the full-frame equivalent for the 15–85.
Thing is, they'd have to sunset the 24-105 lens at that point...which is something they seem hesitant to do. I certainly can't see them even imagining starting a new, cheap kit lens product line when they have a successful one already, and backlogs on lenses that need updates.

Likewise for anything like the 28-200/28-300. Just too hard to get it down to a reasonable price that people will buy it, knowing it inherently has IQ and performance trade-offs

A replacement for the 28-135 will become important as full frame reaches the Rebel price range. This won't happen soon, but probably in 5 years, certainly before 10. I'm predicting an STM version, but not for a few years yet.

I forgot to ask, are you using a full frame 6D/5D/1DX, or a crop sensor camera from the rest of Canon's range?


Lenses / Re: Lenses in the 20mm range

+1 on the TS-E 17.  It was made for interior shots.  The 16-35 f/4 IS may have more uses, but nothing does interior shots better than the TSEs.

That all depends on whether planning to use a tripod whenever light levels are low. IS would be a winner if needing to take shots hand held where a tripod would be a problem, or program does not allow.

I'm happy with my 24/2.8 IS for interiors, and like the focal length for it's fairly realistic view of the space, whilst still including a good part of the interior. Where a wider field of view is more important, then I have been looking at the Canon 20/2.8, whose curvature of field may help for interior shots, and the Zeiss 18/3.5 as mentioned by others. Both of these have a depth of field scale, ideal for capturing interiors.

Alternatively, the Sigma 12-24 has a depth of field scale, but lacks IS. If relying on autofocus, or making your own judgements then I concur with those who have suggested the 16-35 IS. The slow shutter speeds possible with IS will allow stopping down to keep the whole room in focus, whist keeping ISO down to a reasonable level.

Shutter speeds of half to one second can sometimes achieve the blur of people or other moving objects sometimes seen in architectural shots. However, where there is opportunity to use a tripod, longer exposures can do this more reliably.

Let me know how you get on, I'm looking at these options for myself. I'm hoping that Canon continue their roll out their IS primes at Photokina in September. Meanwhile the new 16-35 IS seems the obvious answer for full frame, assuming that a tripod cannot always be used.

Lenses / Re: Help me to decide: 35 vs 50mm
« on: July 27, 2014, 11:46:52 AM »
If I was to only carry the one lens - the one on the camera - it would be a 35mm for full frame.

My current travelling light set up is different to that - I have a 50 on the camera, and a wide (24) in a bag or pocket somewhere. 50 is great for forcing a tight field of view, but there are times when wider is needed.

Canon General / Re: Can anyone suggest the adapter for my lens?
« on: July 23, 2014, 07:45:26 AM »
I am happy with my Fotodiox pro adapter for OM lenses. If outside of the US, Fotodiox have Amazon stores and will mail direct if ordered from there.

It does depend what lens you want to adapt, as previous response.
