Addendum: Choosing your first camera lens

My last blog "Choosing your first camera lens" contained one quite shocking error.  It is mildly embarrassing because I actually wrote an article about a lens I don't own and have never even set my hands on!  It's a long and tedius story* but I actually thought I'd bought this lens: the Sony DT 35mm f/1.8 SAM lens, but in fact I'd bought this one: the Sony DT 50mm f/1.8 SAM lens.  They are both "portrait lenses" and they are both prime lenses but they obviously have slightly different focal lengths.  The rest of the blog entry stands but I thought I would make some small changes to try and claw back some credibility and accuracy.  (Don't worry, I am intending to enter this post as the most boring blog article ever written).


Alteration 1: Subtitle: "Experimenting with my new Sony DT 35mm 50mm f/1.8 SAM lens"

Alteration 2: Paragraph 2: "On a full frame sensor camera this would be a 50mm lens but on a cropped sensor, such as on my Sony A200, this would be a 35mm lens but what I ended up buying, in fact, was a 50mm lens which on a APS-C, or cropped sensor, is equivalent to a 70mm lens(Confused?  This blog has undergone some changes since it was first written and these are explained in the addendum post)."

Alteration 3: Paragraph 2: "This type of 50mm equivalent prime lens was sold to me as a great portrait and landscape camera."

Alteration 4: Paragraph 2: "So I now have the Sony DT 35mm 50mm f/1.8 SAM lens. I've started to do my own tests my early results can be seen by clicking on the test photos above or by clicking on this Flickr set."

Alteration 5: Paragraph 4: "Kurt Munger, a devotee of Sony cameras and lenses, has reviewed the Sony DT 35mm 50mm f/1.8 SAM lens and his great technical report can be found here: http://kurtmunger.com/sony_dt_35mm_f_1_8_reviewid235.html http://www.kurtmunger.com/sony_dt_50mm_f_1_8_samid147.html."

Phew! Kurt is the man to read on Sony cameras and lenses.  I have a lot to learn!

The photographer's brain is missing

*How did this happen?  Is it a sign of the early onset of dementia?  I hope not and I don't think so.  I went into Jessops intending to buy the 35mm lens, saw what I thought was one on the shelves, bought it and walked out of the shop with a lens in a box that said 50mm.  

I even took a picture with my iPhone (left) when I left the shop because I was so chuffed with my purchase.  The 50mm lens box didn't raise any alarm bells in my head because I thought I'd asked for the 35mm lens.  The very helpful shop assistant (god this is boring!) said they had only one lens of this kind left and it was the one I'd seen on display.  I said as long as it worked, and I had the same guarantee, then I was happy to buy that one.  She went into the back of the store to find it's box and sold it to me.  Tonight, Tuesday 8th February 2011, I actually used my eyes and looked at the lens and my world came tumbling down...
