Arrived home today to find the new body had arrived. I'm not going to attempt a full review because there are loads of comprehensive ones about.
First impression out of the box was that it felt really good in my hand - and well balanced once I attached lenses. Certainly much better than the E-300 it replaced. I had been toying with the idea of a power grip but have now decided that I am going to stick with the spare battery in my bag option. Annoyingly I let my almost new spare go with the 300 body because I had been planning to replace it with a 620. Oh I have largish hands in case you're wondering.
I was especially keen to test two things: How good is the IS and how bad is the noise. It was pretty gloomy outside so I allowed a 10 minute battery charge before rushing out. Nothing too scientific. I attached the Oly 70 - 300, extended it to 300, stepped out of the back door and pointed it at a tree trunk at the end of the garden and left the factory settings. No reference to the manual so I guess that means its pretty intuitive to use. Part way through testing I realised that IS wasn't turned on by default as I had assumed. One annoying thing about the defaults was that the camera decides when I want to use the flash - that has now been changed.
First the image stabilisation. I assume the old adage of "shoot faster than your focal length" remains true (and focal length means effective focal length). Sorry guys, the last time I regarded myself as a serious photographer was in the 80s when I made my living with my manual focus 35mm SLR . So on that basis I should be able to hand hold at 1/1000. I stuck to "standard" shutter speeds and ISOs because I had no idea how long the battery was good for - and of course because I'm not the most patient. Olympus claim 5EV and I was expecting 2 so on that basis my first shots were at 1/15th (well that's only 6) and worked my way up.
I was seriously impressed to discover that the shots at 1/15th were actually usable and looked good if all you wanted to do was put them onto a web album without cropping - no go at actual pixel size though. Only marginally better at 1/30th. Of the two shots I took at 1/60th one was perfect at any resolution and the other was pretty soft at full size. I'd give it a go in an emergency - or holiday snaps. At 1/125th I was satisfied with both my attempts. So if my original assumption was correct that's 3EV and I'm happy with that.
Now on to low light performance. It was really gloomy by now so I used auto and started at ISO 400 which was the most I would accept on the old E-300. At 1600 the results were pretty comparable to 400 on the E-300 - that is reasonably ok where there was plenty of light and quite grainy at full resolution in the underexposed areas. For the shots I took I would probably not try to reduce this and regard it as usable - so that's another 2EV and suddenly my "slow" 70 - 300 is looking quite usable. Naturally I did go all the way to 3200. The result was pretty good for a web album but I wouldn't use it for anything else.
I ran the 1600 version through Noise Ninja using the default settings in Aperture and would be happy to print the result. For my test I just ran it on the whole pic within Aperture - personally if I had a decent shot that required that I would do it in Photoshop so that I could use layers to have better control over where I compromise on sharpness. Ideally I would stick to ISO 800 or less but nice to know that I do have the option.
All this low light, long lens stuff has confirmed that the AF is really impressive.
Not sure if this is a niggle but at ISO 1600, f5.6, 1/250 I had 4 visible hotspots - is this something I should take up with the dealer? Its a lot less than my old camera but that was almost 6 years old.
Finally it's worth mentioning the data transfer. I used a 16Gb Sandisk Extreme III card and took a total of 22 shots. Connected the camera to my Macbook, hit import on Aperture and got up to make a cup of coffee only to discover the transfer was done by the time I left my chair. Oops - strike that :mad2: - in my haste to get going I never set the format and the default jpgs are about 1/5th the size of the raws I am used to. Still much faster but I'll give an official verdict later. Hope to get out and about with it on the weekend and post some pics.
