Canon 50Mp 5Ds R digital SLR Camera

I have recently purchase a 5Ds R I have a trusty 24Mp 5D MkIII and I was interested to see how the 50Mp full frame sensor would behave under various conditions

Squeezing that many pixels into a a full frame sensor was asking a lot and because of that the noise levels at moderate ISO's say1600 are quite high compared with the 5D which will go to very high levels with ease due to its  larger pixel size.

So I have been experimenting with a base ISO of 100 to get the best results that means in low light a tripod, in good light Canon's 4 stop IS lenses suffice.

The level of detail available with this sensor is amazing providing the best Canon lenses are used, I use a 16-35mm f4 IS L lens, a 24-70mm 2.8 mkii L and a 100-400mm IS Mkii L lens which covers most of my needs.

File size in RAW at maximum is about 65Mp a huge file size which means a large capacity fast memory card and a very large capacity hard drive.

I am using a Apple iMac and uploading some images to iCloud to save on hard disc space.

Below are two pictures where I cropped the road sign from the centre of the large image file size in RAW was 65mb to gauge enlargement potential.

These images have been exported in small jpeg size for showing here. I chose the "fine detail" setting in the menu and no post edit sharpening was applied

Brodie F1 Brussels sprout

We tried these for the first time as they were recommended to us for their sweet taste.They have been picked whilst small to improve the flavour and reduce cooking time.
We have eaten the small amount of Brussel tops but sadly the snails on the allotment plot had most of them.
The effort to net them was worthwhile to keep the large white butterflies off, so all in all a successful but small crop with beneficial health properties.

Goldfinch

We use to get lots of finches in our garden, sadly that is no longer the case. The general bird numbers visiting our garden in Eastbourne East Sussex are down in significant numbers, even starlings, herring gulls however are ever present in large numbers driven inland by the plentiful amount of food waste giving them lots of free offerings.
It was therefore a surprise to have a goldfinch visit albeit fleetingly today.
My friend Sue at glallotments here  recommends sunflower hearts here for all birds especially goldfinches, I intend to try those in addition to small bird seed mix and fat balls.

A very surprising 50p purchase and its not the goat

I've had a Nikon D200 digital camera for some years but haven't used it for a long while since changing over to Canon cameras and lenses.
I happened upon, in a junk shop, a very early first model Nikon 18-55mm plastic bodied lens with fungus inside and a scratched front element for 50p not expecting much I popped it on the camera and got this frankly surprising sharp and well defined picture of a goat and fishing lake at our local farm shop.
A closer look revealed the fungus and lens scratches were towards the edges of the glass, so at f7.1 (the aperture of these pictures) wouldn't appear but wide open at f3.5 they probably would, so the lens will likely be of limited use for indoor work........still, I now have a usable lens/camera combination.

Shingle replacement and school children on Holywell beach



Contractors have been doing the annual task of shingle replacement due to longshore drift 

Children on the beach doing geography lesson on the shingle losses due to longshore drift

Longshore drift, the erosion of shingle due to wind and tides (see above)

Wind surfing on Holywell beach

                                                         

I gather its harder than it looks

This looked to be the hardest part

I cant see what all the fuss is about
