Decided at last moment I should have a Christmas treat. Got myself a 500mm tele-lens for Carols Canon 40D. Came today and first impression -I luv it.Posted a hand held shot of the moon -today early evening. Cannot post here -as the forum pic posting does not work-have it on Flicker. Glad I tried the mirror lens for the fun-but cannot be compared with the real thing. This lens I have no doubt is a corker.December 22, 2015 at 11:58 am #11011
Ken, you said, “Cannot post here -as the forum pic posting does not work”

Ken >>> Great! Glad it’s OK now!December 22, 2015 at 12:58 pm #11014
You can see all the craters and relief on the moon. Looking good.December 27, 2015 at 11:38 pm #11020
The plan was to upload here the two comparison images taken from the same spot-with a 50mm lens and the one seen here the 500mm lens. The 50mm photo will not transfer over exactly as Ian kindly explored with me just a few days ago. However both are on Flicker to compare. Probably about 150 metres from taking point to subject–the sign. My point being I have long since been drawn to long tele lenses and in that time had some rubbish.The 500mm Mirror lens cost about £200 –in a word—oh John said keep it polite–so in a word –rubbish–class piece of gear but rubbish results. So for Christmas bought myself honest to goodness 500mm tele-lens with no frills. The all metal with excellent quality look and feel and functions all smooth does give excellent results. Now to scare off most this is a manual lens—no auto exposure or focus. But we were brought up on these long before auto stuff–so for me it is bread and butter. I get 500mm lens giving excellent sharp images. I have to manually set the focus and exposure .To focus–look through eye piece -turn focus ring till all sharp- set on manual-set ISO and shutter speed till exposure correct–all very simple.Press shutter button. Have a look on page 46 Photography News at the Nikon very high class 200–500mm lens at an eye watering price of £1177. Knock off £1100–and you have the price I paid for my gem including postage. Made in China–I luv it.-Bit of quality loss here with small image and best seen in Flicker.December 28, 2015 at 11:39 am #11023
This thro double glazing about 30 metres. Strange from Canon picture uploads–the problem seem to be with pics from Samsung not uploading.

“…the problem seem to be with pics from Samsung not uploading.”
Ken >>> Are the files from the Samsung JPGs? (You can only use JPG, JPEG, PNG and GIF on the CPS site.)December 28, 2015 at 2:20 pm #11025
Yes Ian-all JPG and re-checked all ok. A mystery as I have now resized again the original in another photo suite-saved-upload into gallery all ok–but no title-and will not enlarge for drop down list.Will do some experiments with camera as the problem seems to emanate from there.ken—————–Maybe the penny dropped Ian—I think it is the SD card -will check it out. Has some images on -my friend used on his camera which I cannot erase -I expect to find its the SD card and will check it out.December 29, 2015 at 9:21 am #11027
Mmm… the problem can only be due to a couple of things: file size too large; JPG being saved in a slightly non-standard format; hardware failure (e.g. a faulty SD card) corrupting the file during writes/saves.
Try a different SD card?
If the card is OK, another test might be to import the camera JPG file into Photoshop or Elements, downsize it to’640 pixels on longest side’ there, and SAVE AS a jpg file from Photoshop or Elements (which use a standards-compliant JPG format).December 29, 2015 at 9:47 am #11028
I’ve seen your comparison photographs on Flickr and the difference between the 50 and 500mm lenses is incredible. On the 50mm shot I can only just make out the sign post. I’d forgotten just how powerful a 500mm lens is. It’s a specialist lens though of course and is limited in its coverage.
Is it the 50mm picture you can’t load on our forum? If so the file must be OK if it uploaded to Flickr. Can you email me the file so I can check it out? Do you get any error messages when you try to process it? I have come across problems in the past with a filename preventing the file being processed. I changed the name and it was OK.December 29, 2015 at 10:45 am #11030
I think Peter is likely to be right about the file names causing the problem. Just rename them as something really simple. I have known odd things cause problems, such as underscores.December 29, 2015 at 11:01 am #11031
Ah, yes. I’d overlooked this: in filenames, avoid spaces, accents and any unusual characters (apart from hyphens – ie minus signs – which seem OK to use in place of spaces). Spaces are used as end-markers in some systems, so filenames with spaces are not read properly.
That’s why I routinely use the ‘Wiki’ form of naming to include more than one word. For example: ThisIsMyLatestImage.jpg
And if you want to include version numbers or dates: ThisIsMyLatestImage-ver2-151229
(Writing the dates as yyyymmdd or yymmdd makes sure they with always sort in the correct date order.)
But, as John says, if you want to be sure, the best way is to keep it simple: photo12.jpgDecember 29, 2015 at 11:46 am #11032
Thanks gentlemen-great and helpful input. Have followed same procedures since Ian explained to me with no problems.I am pretty sure is is the SD card.————————WELL the mystery deepens. It appears the problem emanates from the TWO Samsung cameras. The Canon and is ok–using the same SD cards in the Leica and that uploads with the titles ok. With both Samsung cameras-the 650 images uploads into my gallery-but no titles.Strange as been using both for a while and previously ok.December 29, 2015 at 1:51 pm #11034
HEY PRESTO–Same SD cards in the Leica and no problem.So some thing to do mwith the Samsungs??-Going back –taken at 50mm setting from the same spot where the above “SIGN”image was taken on the 500mm tele. Phew!!!
