I might be preaching to the choir here but if anyone is like me and is thinking about the 150-400mm from the 300mm f4 then this rambling post might be for you
Ive had the 300mm f4 for just over 2 years and love it to death. The sharpness has always blown me away especially in such a small package (I came from the Canon 500mmf4). I never really got upset with the locked focal length making me miss shots like when a Dragonfly would land too close etc but one thing that always niggled was when going out whether to put the tc on or not. It was always a decision to make. Yes I can add or remove in the field but if getting a bird or insect in an instant you don't have time for that.
I never considered I could get the 150-400 due to the cost but also always assumed it could never match the sharpness of the 300 since that is a prime. Even as much as all the youtubers would say its really sharp and amazing etc. Its hard nowadays to work out who is a brand ambassador or who would dare to say something different to everyone else and look potentially like an idiot.
But suddenly I noticed the lens is 4999 on Cotswolds. Selling on the 300mm would bring the lens price down to something that isnt so eye watering for me. But I am risk averse and pretty sceptical so decided to hire one from lenspimp for 7 days. I really wanted to know how is the weight when on the shoulder as i walk a ton with my lens over my shoulder. I also wanted to see the sharpness for myself, is the IS any better, is the AF any better etc?
Anyways it came today and of course the weather is dreadful but i got to use it on my lunch break in the garden. Even in dreadful light I am pretty shocked by just how sharp it is and how nice the bokeh is. I even tried some mad way off shots of a greenfinch with the inbuilt tc on just to see. Shots I would never even think of with my 300 + 1.4. The versatility has impressed me too. Going from getting a stunning sharp shot of my dog at 163mm (lens ring moved) right out to videoing a goldfinch way away in a tree handheld with the 1.25tc engaged and the inbuilt tc on as well and getting something more than usable.
So far it feels to me (compared to the 300mm bare) the bokeh is better, the AF is quicker, the IS seems similar but that is impressive since its longer and I currently feel like its sharper than the 300mm bare, the 1.25 tc on absolutely blows away the 300mm + 1.4tc imo. But it will be interesting to see what happens if I get any sun.
I will hold off my final judgement till after saturday when i can get out and walk with it but after just 40mins using it I have gone from hmmmm i probably wont as its a lot of money to the CC card is in hand.
Dog was 163mm at f4.5 iso 2000
Greenfinch was 500mm at f4.5 iso 2000 (and was way off)
Handheld video of a goldfinch. with 1.25tc engaged and halfway through i turn on the inbody tc
