The Sigma 135mm f1.4 DG Art is the world’s first 135mm autofocus lens with an f1.4 aperture, designed for full-frame mirrorless systems. Its 17-element, 13-group optical construction delivers crisp detail, while a 13-blade diaphragm produces large, natural bokeh. Dual HLA motors and a floating focus system ensure precise autofocus in a robust, dust- and splash-resistant build with an Arca-Swiss tripod socket and a declickable aperture ring for tactile adjustments.

FAQs:
How does the dual HLA system improve focusing performance in the Sigma 135mm f1.4 DG Lens?
Each of the two focus groups has its own HLA, with different actuators optimised for the movement range of each group. This pairing delivers the thrust required for a bright telephoto and the speed to lock reliably, which helps track subtle expressions and movement. It’s also quiet, supporting hybrid photo and video use.
How do I control the aperture ring on the Sigma 135mm f1.4 DG Lens?
You can de-click the aperture ring for smooth exposure adjustments or leave the clicks engaged for tactile third-stop increments. The Sigma Lens’s lock switch prevents accidental shifts when you want the body to control aperture or when stowing the lens. These controls sit alongside two assignable AFL buttons for on-lens access to key functions.
What material is the Sigma 135mm f1.4 DG Lens constructed with?
Aluminium and magnesium alloys combine with TSC, a thermally stable composite with expansion properties similar to those of aluminium. This mix provides rigidity, reduces weight compared to all-metal builds, and maintains stability across temperature changes for consistent performance.
Do the included accessories provide any particular features?
The LH1126-01 lens hood is made of CFRP - a carbon-fibre-reinforced polycarbonate - with a push-button lock for secure attachment and quick removal. The supplied TS-181 tripod socket is Arca-compatible and removable when you prefer handheld shooting; a protective cover is included for clean lines once detached.

Buy now pay later
The Buy Now Pay Later option comprises a 36 month loan following a six month deferral period.
During the six-month deferral period, it is possible to pay off the loan, either by way of a lump sum or in smaller amounts. If the loan is partially repaid within six months, the remaining interest will be adjusted to reflect the new balance. If the loan is fully repaid within the six-month deferral period, then no interest is payable, however, a £29 early settlement fee is payable in respect of repayments within these six months.
Following the six-month deferral period, Novuna Personal Finance will initiate a monthly direct debit payment for the remaining duration of the loan. Interest will be charged at a rate of 18.9% APR (representative) on outstanding balances (backdated to the first date of the loan). Novuna Personal Finance will send a reminder letter approximately one month before the six-month deferral period is due to elapse.
