Whenever these threads come up which is pretty often, I just have to wave the Peak Design flag.

Often when that flag is waved, I ask how the Peak Design system attaches to an Arca-style lens plate (a real one, not Peak's little square plate that may not allow balancing the load in a tripod clamp).

Also, just to point out:


I know everyone highly regards Lee filters, but what about Cokin?

Cokin filters often have an undesirable color cast.  But...their Z-Pro holder is a good alternative to the Lee holder.

I'd skip the Canon bracket.  Not only is it ungainly, it places the flash very close to the lens axis...and that means a high chance of steel eye (the avian equivalent of red eye).

There are good options from RRS, Wimberley, etc.

Sounds like we should be praying for a 300mm f/4 IS DO like Nikon just delivered!

You can pray for a lens with last-generation, outdated DO technology and a 'black box' warning about flare if you like.  I'd prefer something better.

I will keep the 200-400 next to the 100-400II, as the last one gives me a possibility to travel light and compact.

For travel, I ended up preferring the more compact 70-300L, and eventually sold my (original) 100-400L.

I'd buy the 100-400 II, because I already have the 600 II. 

I am looking to get me a BlackRapid strap or something in that line which I can use with my 5D3. In most scenarios I use my the 5D3 on my tripod for landscape shots, but at times I like to detach it from the tripod and shoot handheld. When handheld, I like the camera to have some form of secured strap which I can use to wrap around my wrist or leave it hanging on the side of my shoulder.

I am looking for something that is reliable, secured, and I can attach/detach the strap with ease depending on my shooting scenarios. The heaviest load it will need to withstand is 5D3 + 70-200 IS II. Any advice or recommendations? Oh also anyone used a wrist strap, any recommendations on that? Thanks.

I use a Blackrapid strap with a Kirk 1" clamp attached to the lug – comfortable to carry, easy to move clamp from the Arca plates on body to lens, or remove for tripod/monopod use.

Damn you, Canon – you keep coming up with clever ways to deplete my gear fund before it accumulates sufficiently for the 300/2.8L IS II.

Does IBIS stabilize instantly?  Or, is it 'always on' (and how does that affect battery life)?   How effective is IBIS with 300mm and longer lenses?

Its always on. Must cost some draw on battery. Since most pocket cameras has it I not sure its significant even if DSLR sensor is somewhat larger = somewhat more energy needed.

On DSLR effectiveness to my knowledge there is no agreed way of calculating this. Tests seem to vary widely.

The main advantage of course is that with IBIS all lenses are stabilised.

Recently IBIS also combines with in-lens stabilisation being on (have no info how this boosts the overall IS effect). After it has been shown you can have both I really hope Canon implements this.

Thanks for the info!

The reason is that it takes just an instant for the IS to "settle" when on (one of the disadvantages of in-lens IS that is seldom mentioned on Canon-forums were there seems to be a taboo against claiming any advantages of in-body IS

If I were to do this simply, I would try something rather funny:

1. I would choose the smallest possible shoulder bag that would carry the photo equipment.
2. I would choose a general purpose bag in the dimensions you mentioned.
3. I would put the small shoulder bag inside the bigger one.
4. I would fill the rest of the bag with all necessary items.

It's not funny at all!  For overnight trips, I often pack my photo gear into a Lowepro Flipside 300 (which it is essentially a perfect fit for the gear the OP lists), then put that backpack, it change of clothes and a sundries kit into a Storm im2500 carry-on hard case.  That way, the gear is protected in the event that it must be checked (hasn't happened domestically with priority boarding, but it might, and standard sized cases don't fit in the regional jet overheads).  It also gives me a way to lock up the gear in a hotel room.  The case rolls conveniently through the airport, and I have a dedicated photo backpack for outings at my destination.

For longer trips, there's not enough room to store a wardrobe in the carry-on so I'm checking a bag anyway.  But I still do the above, so I have at least one change of clothes if the checked bag gets lost.

Both of them have a fixed size. I'm not sure how much that matters in daily life, maybe one gets used to a 45L backpack ;)

I know there are carryon photo gear packs that will hold all your gear and clothes, etc.  What I'm suggesting is an expandable backpack like the Kipling Hiker and a photo gear insert like the Gura Gear Chobe.  You zip open the expansion section of the pack for your clothes, then at your destination you unpack the clothes and collapse the pack to hold just the photo gear.

Note that I suggest the above as concept examples, I haven't checked to see if they're the right sizes.

I understand your concept.  I'm not aware of such a dedicated photo gear bag/backpack, but if one exists I'd be very interested in buying it!

An alternative to consider might be an expandable general purpose backpack with a photo gear insert, as both of those do exist.  It would then be a matter of finding a pack where the collapsed size just fits the gear insert.

Unlike the others I very rarely use the IS on my Canon 800 F5.6 L IS. Whilst I will use it if needed I haven't actually taken a shot in anger (with this lens) using IS since Jan 2014.
Since using the 800mm lens without IS I am getting a higher hit rate (especially on moving subjects like BIF) and faster AF. The differences are only slight but they are there. The above also applies to my 300 F2.8 L IS etc.
As you can see from the other posts most prefer to use IS - I do not, even when hand holding, though it is handy to have in reserve if the light is really bad!

You also don't have the MkII version(s) of the lenses.

They don't make it yet! I did try a 500 F4 Mk2 in mode 1 and it seemed the same as mine though I didn't try it for long enough to make any conclusions.

You mentioned the 300/2.8, of which there's a MkII.  I've done some formal testing of IS on vs. off, there's no effect on sharpness IF the IS system is fully active.  If you just mash down the shutter, IS is in the process of 'spinning up' when the exposure happens, and that can decrease sharpness (can be worse than handholding).
