DOF is not a deciding factor in IQ or choosing a lens as a smaller aperture number simple means u can have a shallower DOF. 2.8 is CAPABLE of having a shallow DOF, but it is not always shot Wide Open neither. 3.5 wouldnt be able to blur out the background as much as this.
Bro,
Not sure if you seen this.. Chk out the review from Kai..
I am not sure if i am going to make the right assumption here.
Comparing F2.8 Non IS and F4 IS:
F2.8 - F4 is around 1 stop diff
F4L IS has an IS of up to 4 stop.
F2.8's weight is almost twice of F4
If i compare purely on weight and IS, F4L should be a better value for money.
Then again, it's my own thought as weight is a critical consideration via my end.
F2.8L IS of cos has a better bokeh, but there is a price to pay, 2 to be exact here, Price and Weight.
If you do not mind the weight and price and wants assurance of the sharp tack photo, get F2.8L IS Mark 2.
If not, i believe a F4L IS Mark 2 should do you the trick.
For better bokeh, Canon 85f1.8, 100mm f2 or 135mm f2L should do the trick
I will go for f4L IS Mark 2 and 85f1.8 or 135L in this case. I believe it is better and value for money.
Further more, f4L IS is weather sealed
Afterall, it's up to TS to choose
Cheers
sealover said:I just got a 70-200mm f4 IS lens and I love it! It's fast and has a nice bokeh.. Because of it's lighter weight, I can carry it to shoot sports pics without feeling tired that quickly...
Initially, I was struggling between these 2 lenses as well.... However, I decided to get the f4 due to the extra weight of the f2.8 and I'm unsure whether I will be able to take a clear/sharp photo without a tripod if it doesn't have the IS.... If I were to get the f2.8 lens, I would definitely get the IS Mark II! But I'll need to save up more for it! =)
Some recent wildlife photos taken with the light-weight 70-200 f/4L IS:
Oh, did I mention the lens is relatively light-weight?![]()
