    Canon RF 200-800mm IS USM

    And a couple of others. The dragonfly was 1/664, f9.3 ISO 1600 at 800mm, The Linnets 1/790, f8 ISO 3200 at 481mm. Again crop and export from DPP without any adjustments.

    Canon RF 200-800mm IS USM

    I purchased one from Cotswold Cameras and including ordering and delivery days it took 12 days covering 2 weekends and a bank holiday. As someone else said, the weight is mostly in the body so extending doesn't cause a balance issue. Though I can hand hold I wouldn't want to do this for long so...

    Canon RF 200-800mm IS USM

    Here in the UK I called in the store of an on line dealer the other week and they said 'think we sent out a couple the other week' and they 'hoped' to get hold of one for an in store event this month. Only one on line official retailer puts a date up and that's limited stock in June. It seems if...

    Many thanks for that

    Small Bird Newhaven UK

    My wife would be grateful if anyone could ID this bird for her. Taken near the sea close to Newhaven UK today 18th March 2024. It was very small, the photo shows it sitting on a bramble. Not a great photo as it was some distance away, have included a very blurry in flight in case that helps...

    I've got a Canon R7 and need to update my lenses

    As someone who's also pondering the choice I put my R7 with the 100-400 on the scales which came in at 1280gms. I nearly always have the 1.4 teleconverter on which takes it up to 1505. The 100-500 would make it 2160 but while the quality would be better the reach would be less so if I add the...

    Great Northern Diver

    Some at RSPB Dungeness at the moment and we were told they're quite rare there too. Much better picture than mine.

    Mirrorless camera help?

    I have a similar setup to you but with the 65mm ATX, yours will gather more light and be much better than mine. While I've been delighted looking through it I've always been underwhelmed by the quality of the photos using a Canon M50 on the TLS-APO, at times the guy next to me holding an ancient...

    Canon RF 200-800mm IS USM

    I've wondered about the 100-500 too as I know I'd find it more manageable the older I get but I also know I'd likely have a 1.4 extender on it most of the time at which point because of the design it's almost the same size as the 200-800 and not much less in weight. As I currently have a...

    Beginner

    Just before Christmas I bought a R7 and the RF100-400 from John Lewis in their 20% off sale which along with Canon Cashback came to what I thought a very reasonable £1526. Also picked up the 1.4 teleconverter from Canon which with cashback was £370. Coming from bridge cameras and an M50 with an...

    Canon RF 200-800mm IS USM

    The official UK Canon store has removed the 1st April date and now just says out of stock. You do wonder if all the initial production has gone to You Tubers which is a fair marketing strategy but announcing a product you can't supply seems bizarre. If they really didn't expect the demand then...

    Swarovski ATS 80 25-50 W vs 20-60 vs ATX 85

    The T42 to EOS-M adaptor arrived yesterday and at £11 incl p&p the cheapest part of the kit. While the TLS APO cost a fortune even buying it at a much reduced price it is very easy to use just slipping on and off. Weather preventing much of a play but have already noticed the depth of field...

    Swarovski ATS 80 25-50 W vs 20-60 vs ATX 85

    From October 3 you'll have a further choice of the ATC/STC 17-40x56 which is a lot smaller and lighter than both and I think will be £1820 (subject to change) https://www.swarovskioptik.com/gb/en/birding/products/spotting-scopes/atc-stc

    Swarovski ATS 80 25-50 W vs 20-60 vs ATX 85

    I've had a reply from Swarovski who have confirmed their adaptor is an EF mount. Think the confusion arises as my Canon is a EOS M50 model and the mount is a lot smaller than the EF, just taken my EF and EF-M lenses out and the difference is substantial hence I have an adaptor to fit the EF...

    Swarovski ATS 80 25-50 W vs 20-60 vs ATX 85

    On the digiscoping and camera adaptor, I've had a reply from Swarovski who I also think don't understand that mounts for a Canon EOS camera and a Canon full frame camera are different as they think the same adaptor will fit both.
