Thanks Ron, not sure how I missed that but yes that has done the trick !
I've used a Think Tank Digital Holster 50 V20 for the last few years: fits with either the 300 or 100-400 with or without either TC if used. I used it for a few years with my previous 7D2/400 combination & still "works" as new. Has a couple of external pockets for spare batteries/cards etc.
Ok thanks, I must have accidentally pressed it while raising the lens to shoot. Will just have to be more careful ! Sorry only got this a week ago so this trip is a bit of a crash course ! Fortunately nothing too rare on the IoW, just red squirrels, dartford warblers and wall lizards !
Yes that's exactly the option I'm looking for in the OM1. Under the AF menu there is an option to "reset lens" which is currently "off" but can be switched to "on". Guess I need to select "on" and then find out how to reassign the function of that button elsewhere in the menus (I've not tried to change the function of any camera buttons yet as still finding out how the flippin' thing works in default mode
.
only had it when i put the camouflage lens coat. it also made the focus with the fn button a bit slow. guess i have to take it out.
First thing would be to query if you see the same thing using the bare 300mm with the same settings. If not it sounds like it could be a limitation of the reduced light (just my thoughts...).
Thanks Chris. Yes I'm using C-AF and small square. I don't have the issue with just the 300mm so it must be the light. I'm surprised I don't see the camera attempt focussing, passing the target as it attempts to focus too near to too far and back without picking the target up - rather it just seems to "give up" and not change focal length. It seems to help if I move the lens around over the area I'm trying to photo rather than just holding still, as an alternative to focussing on something half way. I guess I will just have to take the 2x off in better light conditions that I was anticipating. Trial and error, still early days.
My OM1 + 300mm + 2x is the same: at least in poorish light it won't autofocus from close to distant in one jump without a nudge (ie by quickly helping it to the right ball park with manual focus or focussing on an intermediate distance first). Once in the right ball park - close or far - it does autofocus quickly though. I haven't yet tried the 1.4x instead, but I still like the 2x and haven't yet found it to be a major problem in use.
I’m using the 100—400 with 1.4x converter in good light and have a similar thing with bird detect on, it isn’t as bad without the converter but does struggle if the bird is quite hidden or in bushes. I have set the top front button to object detection so can quickly press it to switch to single point focus, the lens then looks for focus on anything, a quick press again switches it back to object detection and it will then find the bird.
Final question I promise
. So i've set up C1 for perched bird and C2 for BIF. Front cogwheel changes exposure, back cogwheel changes aperture (rare I will use that). I think the only thing missing is the quick single button press to switch to single focus point/S-AF quickly for part hidden subjects. Presume you programme the "Home-AF" or "AF-On" buttons for this and once programmed you just press to switch and then press again to switch back to standard C1 or C2 ? Thanks.Well, I've found I get more or less the same without either converter, ie with the bare 300mm and the OM1 set to C-AF, 4m-infinity, smallest focusing square and bird recognition on or off, it won't autofocus from close to far in one go and it's reluctant to focus from far to close in one go, so marginally better than with the 2x converter added, but not by much.
